I am a maintenance man. One of our employees broke a brand new 3 day old battery. I fixed the crack first. Luckily I did not return the old bad battery yet. So, dumped the acid from the old battery into a plastic bowl. I used a plastic funnel and put a coffee filter in it to strain the old nasty acid. I strained it twice. Then I added the old strained acid to the broken new battery. It has been 3 month so far and so far there is no problem at all.

Hi, for any of you guys using the CEN- TECH battery tester the switches can sometimes eventually give trouble. It's a good tester, I like it. The switches are not that difficult to replace if you're good with a soldering iron. In many cases a squirt of a good quality switch cleaner like Philips or Servisol will cure the switch problems. These type of switches give trouble on many makes of electronic equipment. Don't use WD40, as it's not designed for that. Remove the back cover. You can take out the entire PCB (tiny screws) Mask the screen with tape & cover round the PCB with toilet tissue. Spray quick, tiny bursts, carefully into the top of each switch, & click a few times as you do it.
The reason why I am asking is because the Auto Zone sells sulfuric acid to put into batteries, but you have to dump out the old acid. So I was thinking, desulphate w/ epsom salt first, then dump the old acid then add the brand new battery acid.
I believe you can get battery electrolyte (acid) at any battery dealer. They sell it in cardboard boxes with a heavy plastic bladder inside. I have three gallons in the barn that have been there for about 5 years and haven't leaked a drop. I know glass will contain it but so will a battery, and the battery case is plastic. So I believe some plastics will safely contain it and do not have to be glass.
For the record, the meter is not telling you 759 OHMS 'across the terminals' but that the INTERNAL, series resistance of the battery is 759 MILLI OHMS = 0.759 OHM
Sir tnx 4d informative video..I want to try can u tell me how much Epson to put on a 200amperes deep cycle battery for desulfatation. and should I first drain my old battery solution b4 put some Epson salt and distilled water
Just a friendly usability suggestion: Either label your videos "1 of 4", "2 of 4", etc. or, better yet, combine into one single video. You have way too many videos to easily find which is which, nor to determine which is the first in this "series".
when a fairly new battery in the hot summer is low on water are you suppose to use regular distilled water or does it also need something else to keep the acid ration correct?
MrAgnostic long lasting, if it works, 6 months to multiple years depending how bad the battery is. I have a car battery from 2003 count it is currently in my modified battery powered lawnmower. The lawn more uses a car starter Motor to turn the blade. it is now 2019, and I can still cut 1/4 acre on a single charge. I did have to add some fresh acid though, as it over last winter it did boil out a couple times when I refilled
I believe it is always better to use electrolyte (battery acid) as a replacement fluid for a battery as opposed to distilled water. Distilled water is fine for say topping off a low cell, but replacement should be, in my opinion, battery electrolyte.
Not sure I would call it "desulfate" when magnesium sulfate (Epsom Salt) is being added. Adding some sort of basic solution (such as sodium bicarbonate, or "Baking Soda"), first, could help to clean the surface of the plates. Then, after a thorough rinse with de-ionized water, add some Epsom Salt to create an ionic solution for the battery plates to use.
Problem with putting baking soda inside the battery is if you don’t get it out it will constantly neutralize the battery and it’s dead. That’s said I do agree if you know what you’re doing you can clean it thoroughly but the method here is just fine for a quick fix and I’ve seen batteries last 2-3 more years after a quick fix like this. So I wouldn’t call it wrong in so many ways.
i have an atv battery 12v 15 amph it has been sitting in the weather for 14 years its empty when i added electrolytes it jumped from 6 to 9 volts what can i use other then electrolytes the amount i should use ect
+KmanAuto need help..urgently my battery is giving 10.5 volts..i think one cell is dead.. i find it through multimeter.. i am going to clean and refill it with acid and water..can you tell how can i clean it from inside...can i use mineral water or anything better?
Will the acid on the top of the battery cause burns to your skin? I know once it dissolved my clothing and the upholstry on my car floor but if i get a little bit on my skin would i be fine, I have a similar interstate battery
acid is acid no matter where it is, inside or on top of something makes no difference. Once you get it on your hands or skin, even if it is dry crystallized salt forms of it, once it reacts with the moisture in your skin it begins reacting immediately until you wash it off.
I am wondering if anyone has ever employed a device that when attached to the battery, or the battery set into the device, creates a strong but very fine vibration throughout the battery while the epson salt solution is used. It seems to me that the vibration of the lead plates within the battery may accelerate the desulfation of those plates. Another idea I had was to add a very fine abrasive to the epsom salt mixture, like diatomaceous earth. Now imagine a battery set into a cradle that acts as a spindle allowing the battery to be tilted at any angle. On the bottom of this cradle is some form of device that puts out very high frequency vibrations but not so intense that it damages the battery. Take for example an old, variable speed, electric sander attached to the bottom of the battery cradle. Then employ the use of a very slow turning motor that literally spins (very slowly) the entire battery so that the fine abrasive material is evenly distributed. This seems sound in theore. Quite literally the internal lead plates, after a few hours, would be scoured clean right to bare metal again. The process could be repeated several times with a rinsing solution to discard any abrasive material as well as the sulfate buildup. Has anyone ever heard of this or any ideas of why it would or wouldn't work? KPE DRAUGR 4-27-2014
This actually works. I could only get about 3 seconds out of a battery I thought I could fix by flushing out with water and adding pure sulfuric acid. Never do this by the way as the battery almost went into meltdown. the battery would charge to full in about 3 minutes and discharge on an inverter in about 3 seconds. After doing this it ran for about 15 minutes on a water pump. I will keep charging and discharging and see if it gets any better.

I am using VERY expensive 6 volt (wired together to get 12 volt) batteries for my backup solar system. The whole thing crapped out on me a few weeks ago after running fine for over a year. All the fluids are above the plates (Thank God) but I am having a problem getting them to take a full charge. From what I remember they never really performed as well as I thought they should. There are eight of these big Interstate batteries (about twice the size of a normal 12 volt car battery each). When connected to the Aimes 5k Pure Sinewave inverter they never really held up as long as I expected. Just running the lights at the house and an occasional TV I am lucky to get 10 hours of use before the low power warning beeper starts going off. Is this normal and I just need more batteries or is something wrong. I have separated the batteries and charged them independently. When checked individually for six volts they register just barely in the green, but under a load fall immediately to the weak side of the (Harbour Freight) load tester. When connected 2 at a time for 12 volt they peg the 12 volt needle nearly to the red, but under a load for ten seconds they drop to about the halfway point between good and weak. Are they performing as they should and I'm just expecting too much or is there a problem?
@@KmanAuto Hmmm. For some reason I assumed that if you only add epsom salt without emptying the acid, you are creating a different compound by combining sulfuric acid, magnesium sulfate, and water. Well I'll give it a shot then. I already bought replacement battery acid due to my assumption. Thought I would need to pour it all out. I have 1 cell that has not responded to hitting it with high juice at intervals. Every other cell woke up perfectly. At the beginning, one tiny bubble every few minutes. Now the second I hit it with any charge at all, 5 cells start to vigorously boil. But 1 simply does nothing. So I guess we'll see.. Thank you for taking the time to respond. Because of that new subscriber.
@@coachtim6188 Thank you for subscribing! As for emptying out, my assumption has always been emptying everything out was to remove any particulates or contaminants in the battery. You could possibly do the flush after adding the epsom salt and letting it dissolve the sulfate. Simple break down as to why you “may” want to dump it, Deep cycle batteries for example, the plates don’t go all the way to the bottom. there is a nice sized gap before the bottom of the battery. This allows sulfate and contaminants to drop to the bottom of the battery. That prevents dead shorts. Starting batteries, have a much much smaller gap, marine deep cycles a bit of an in between gap. That’s because those batteries are generally not deeply discharged as often or at all. A charged battery does not develop sulfate as quickly or even as much. On a badly sulfates battery, that drop space below the plates may fill up, and if it touches between plates you get a dead short, and permanent capacity loss. As for your battery, the 1 cell that isn’t bubbling, may be the good cell. the ones that are bubbling, may have high resistance. it also could be the opposite. might need to take a multimeter to each cell and check voltages as well as check the gravity.
@@coachtim6188 instead of hitting with high currents with a desulfator, instead switch to low current. my main desilfator uses a 80 mfd capacitor. my slow one uses a 10 and i also have a 5. Desulfation, depending on how bad, can take a LONG time. When I do customers golf cart batteries, I put them on the slow one, and then let them sit all winter. My personal golf cart is using marine batteries, not even golf cart batteries with the thick plates. Finally switched the batteries out last summer. They were 12 years old and i could still use it all day around our motel we own. Batteries still worked, we are using 2 on the pontoon, one as a back up other as the accessory/radio battery and starting, and the third (only used 3 12v batteries, instead of 6x6v batteries) Third went in the lawnmower.
If you is interested in battery reconditioning the best results that ive ever had was by using the Magic Mender Wizard (i found it on google) without a doubt the best info that I've tried.
An off topic observation for those lured by creative marketing terminology. The battery is labeled as a deep cycle battery; for this battery this means it can be depleted of charge and recharged... nothing new for a lead acid battery. The technical term deep-cycle applies to ni-cad batteries, which requires depleting the charge entirely using a deep-cycle charging system for recharging; to prevent a memory charge....it is not a plus!
Not just a creative marketing term. A Deep Cycle lead acid battery compared to a starting lead acid battery have much different characteristics. Starting Lead Acid batteries usually have thinner plates and more of them, to allow them to provide a high amperage burst, such as what is needed when starting a car. Deep cycle batteries usually have less, but MUCH thicker plates, which allows them to be deeply discharged and then fully recharged again with little to no harm done. If you deep discharge a starting battery, you "MAY" get 10 complete discharges out of it before it's shot. Where as you should easially be able to get 300-500 discharges out of a deep cycle battery. Hybrid deep cycle batteries are a marketing term. They have more intermediate sized plates, somewhere between a starting battery and a deep cycle. These are junk.
Actually kay ger, a 'Deep Cycle' battery has a key characteristic not normally found in 'starter' batteries, and that is the MUCH heavier, thicker, often larger lead plates inside it that allow it to go to low (not full) discharge without plate damage (due to material mass loss). Do this with a thin-plate 'starter' battery and you won't have a battery after a dozen tries at 'running your trolling motor all night', where a true 'deep cycle' can be recharged a hundred, two hundred or more times - depending on depth of discharge, method of recharge, and care throughout. As for the 'technical term deep cycle referring to ni-cad', no kay ger, they were making 'deep cycle batteries' (lead plate wet cell 12v) and marketing them as such as far back as the late 1950's. Pirating a term already used only causes confusion. 'Deep Cycle' intentionally means to 'cycle deeper into discharge than is otherwise advised for comparable thinner-plate batteries'. How do I know? I am a retired mechanical engineer who spent over 30-years designing special vehicles with advanced onboard electrical systems, especially AC/DC circuits; and spent more time fighting the ills of wet-cells and their inherent problems, than most people even in the battery industry will ever have to deal with. The company I was with was actually the first to consistently apply Peukert's Curve to determining charge capacities vs customer demand on systems (other than NASA), to ensure that the battery bank could support retail expectations.
***** might want to include the reason a starting battery turns to junk, plate deformation that generates shorts, this can also happen during overcharging and letting a battery run dry while trying to charge it. Lots of reasons for early demise of a lead acid battery. kay ger the use of deep-cycle in a ni-cad battery is a requirement while deep-cycle in a lead-acid battery it is a feature.
Mikej1592 Deep cycling of a lead acid battery is not a necessity, it's a marketing labeling gimmick! Sure there are heavy batteries and light duty, etc... all kinds of them, but the technical term "deep cycle" applies to how a battery is charged. If a battery is being damage under load, then either the load is too much for the battery or the battery is is too little for the load. Starting batteries, Deep Cycle, etc are marketing terms not technical terms, Off topic: Once, I helped my nephew build a fence, he's a fresh out of college mechanical-engineer. He insisted to purchase the concrete at a certain big-box store across-town because he had a corporate discount there. After arriving there, I backed-up to a pallet ready-mix bags, priced at $2.99 each for a 90 lb.bag, then I wait for him to go inside to pay for what we'll need. After about a half-hour latter he comes-out pushing a cart of 60 lb. bags of the same brand of concrete but with different labeling proclaiming it "Fence Post Concrete". I asked him how much did a bag of that cost? He said $3.65 a bag, I said, there went your discount, he say's... Oh well, but it's made for fence posts!
Make sure you mix a half a box of Epsom salt in distilled water and then pour it and distilled water in the battery you might want to drain the battery into a bucket but wear gloves when you do it protect yourself from battery acid
I have a Mega-Tron probably around 2003/2004 year battery that I dumped the old water/acid and used the baking soda/distilled water solution to boil it out and flushed again with distilled water. Before I dumped the old acid out it showed a reading of little over 5 volts afterwards with just distilled water showed a reading of less than 2 volts. I then mixed a solution of 8 ounces alum (food grade) to 1 gallon distilled water and used a old 6 amp battery charger from late sixty's early seventy's that still works fine but when hooked up to my alum battery experiment the meter on the charger reads 0 than jumps to 8 than back to 0 then back to 8 also battery feels warm not hot to the touch but warm. So I'm assuming this battery is junk (direct short) or I'm I missing something? Not that familiar with batteries just learning I have two other deep cycles that read around 5 volts to try and re-cover.
I'm replacing a 420 CCA battery with the same one which is this one :- www.repco.com.au/en/globes-batteries-electrical/batteries/batteries-automotive/repco-extra-heavy-duty-battery-12v-420-cca-239l-x-172w-x-218h-mm-58-red/p/A9378180 The one I replaced 3 years ago,well a cell started to go bad in it & the cranking voltage got down to 8-9 volts so I bought a new one today. Note I usually check the open circuit voltage before installing the battery & it was 12.1 volts on the brand new battery & the gravity was way down in the red on the hydrometer. I'm not sure how old it is, I think it may have been sitting on the shelf for a while but I have it on charge overnight to bring the voltage back up !
Sulfuric acid stays acid, it does not go bad, it is a very strong corosive acid, you could dump the acid out get new cells and filter the acid into the cells, don't know how you'd filter it since only glass will contain it, there must be a way.
so, you show a conductance testor and you never test specific gravity for each cell? when you say the battery is "weak," how do you know unless you use a carbon pile load testor or test the gravity? Seems like we need a crash course in battery testing!
a 5 dollar voltmeter would TELL you exactly the same as that $ tester; 10.7 volts THAT is it, ONE bad cell; battery has 6 cells (2.1 volts x 6 is 12.6 ) , so 10.7 volts means ONLY FIVE cells are working;
Use a coffee filter. Of course it (the acid) will eventually eat the paper but not immediately. You will have time to strain out any trash. But to be honest, I would just purchase a new container of electrolyte (battery acid) from any battery dealer (granted that you can budget it. There is nothing wrong with reusing things to save money. Lord knows that I have had to many times). I have three gallons in the barn. It comes in a cardboard box of all things. Of course inside the cardboard box is a thick plastic bladder that actually contains the acid. from the bladder is a small rubber hose with an old fashioned pinch valve to control or stop the acid flow from the battery. Wear old clothes, rubber gloves if you have them and of course safety goggles. Battery acid in the eyes hurts a lot. I know from experience.
Umm.. Military grade batteries = insanely expensive. Jump with a resister? I think you need to do some reading up. Resistors will DRAIN power, not charge.
I found the ad in a magazine and they are dry cell and were in rv magazine and it said clearly if voltage dropped below 12 you would simply jump it with a resistor and you'd get the full voltage instantly. I do know that sounds funny, but these were unlabeled green batteries that military uses in all vehicles and they don't have time to charge a low battery, so something as quick as this is a requirement, these batteries were also said to last 10-15 years or more. I will do more looking online to find them.
+LuxorVan The winding's in an engine starter are basically resistors. So if I use one of those and my battery's dead I can just turn the key and voila? Trust me dude, too good to be true.
All I know it claimed that it had two terminals you touched a resistor to, it would renew the voltage. They were in the back of an RV magazine years ago! I was only stating their claims! Probably like 1999-2001! It obviously wouldn't work on normal batteries! But if it were available they would be a great investments!
LuxorVan The back pages of any magazine are filled with crap man. The technology may exist though and you get a plus in my book for your enthusiasm. Cannot and will not gain a charge from applying a load (resistor) to a battery. The least it could do is desulphate the lead plates in the battery, still needing charging before operational (kinda what this video is covering). Remembering stuff from '99 gains you the credit of a Human Being. Keep it up mate (mostly everyone else cares about nothing) :)

When connected to the Aimes 5k Pure Sinewave inverter they never really held up as long as I expected. Just running the lights at the house and an occasional TV I am lucky to get 10 hours of use before the low power warning beeper starts going off. Is this normal and I just need more batteries or is something wrong. I have separated the batteries and charged them independently. When checked individually for six volts they register just barely in the green, but under a load fall immediately to the weak side of the (Harbour Freight) load tester. When connected 2 at a time for 12 volt they peg the 12 volt needle nearly to the red, but under a load for ten seconds they drop to about the halfway point between good and weak. Are they performing as they should and I'm just expecting too much or is there a problem?
These batteries are probably sulfated due to deep discharges and incomplete charging.
Aren't you supposed to empty the acid out before adding epsom salt?
no need or reason to
unless it’s cloudy and contaminated, then replace it with fresh
@@KmanAuto Hmmm. For some reason I assumed that if you only add epsom salt without emptying the acid, you are creating a different compound by combining sulfuric acid, magnesium sulfate, and water. Well I'll give it a shot then. I already bought replacement battery acid due to my assumption. Thought I would need to pour it all out. I have 1 cell that has not responded to hitting it with high juice at intervals. Every other cell woke up perfectly. At the beginning, one tiny bubble every few minutes. Now the second I hit it with any charge at all, 5 cells start to vigorously boil. But 1 simply does nothing. So I guess we'll see.. Thank you for taking the time to respond. Because of that new subscriber.
@@coachtim6188 Thank you for subscribing!
As for emptying out, my assumption has always been emptying everything out was to remove any particulates or contaminants in the battery.
You could possibly do the flush after adding the epsom salt and letting it dissolve the sulfate.
Simple break down as to why you “may” want to dump it,
Deep cycle batteries for example, the plates don’t go all the way to the bottom. there is a nice sized gap before the bottom of the battery. This allows sulfate and contaminants to drop to the bottom of the battery. That prevents dead shorts.
Starting batteries, have a much much smaller gap, marine deep cycles a bit of an in between gap. That’s because those batteries are generally not deeply discharged as often or at all. A charged battery does not develop sulfate as quickly or even as much. On a badly sulfates battery, that drop space below the plates may fill up, and if it touches between plates you get a dead short, and permanent capacity loss.
As for your battery, the 1 cell that isn’t bubbling, may be the good cell. the ones that are bubbling, may have high resistance. it also could be the opposite. might need to take a multimeter to each cell and check voltages as well as check the gravity.
@@coachtim6188 instead of hitting with high currents with a desulfator, instead switch to low current. my main desilfator uses a 80 mfd capacitor. my slow one uses a 10 and i also have a 5. Desulfation, depending on how bad, can take a LONG time. When I do customers golf cart batteries, I put them on the slow one, and then let them sit all winter.
My personal golf cart is using marine batteries, not even golf cart batteries with the thick plates. Finally switched the batteries out last summer. They were 12 years old and i could still use it all day around our motel we own. Batteries still worked, we are using 2 on the pontoon, one as a back up other as the accessory/radio battery and starting, and the third (only used 3 12v batteries, instead of 6x6v batteries) Third went in the lawnmower.
Don't forget to clean those posts!!
If you is interested in battery reconditioning the best results that ive ever had was by using the Magic Mender Wizard (i found it on google) without a doubt the best info that I've tried.
An off topic observation for those lured by creative marketing terminology. The battery is labeled as a deep cycle battery; for this battery this means it can be depleted of charge and recharged... nothing new for a lead acid battery. The technical term deep-cycle applies to ni-cad batteries, which requires depleting the charge entirely using a deep-cycle charging system for recharging; to prevent a memory charge....it is not a plus!
Not just a creative marketing term. A Deep Cycle lead acid battery compared to a starting lead acid battery have much different characteristics.
Starting Lead Acid batteries usually have thinner plates and more of them, to allow them to provide a high amperage burst, such as what is needed when starting a car. Deep cycle batteries usually have less, but MUCH thicker plates, which allows them to be deeply discharged and then fully recharged again with little to no harm done. If you deep discharge a starting battery, you "MAY" get 10 complete discharges out of it before it's shot. Where as you should easially be able to get 300-500 discharges out of a deep cycle battery.
Hybrid deep cycle batteries are a marketing term. They have more intermediate sized plates, somewhere between a starting battery and a deep cycle. These are junk.
Actually kay ger, a 'Deep Cycle' battery has a key characteristic not normally found in 'starter' batteries, and that is the MUCH heavier, thicker, often larger lead plates inside it that allow it to go to low (not full) discharge without plate damage (due to material mass loss). Do this with a thin-plate 'starter' battery and you won't have a battery after a dozen tries at 'running your trolling motor all night', where a true 'deep cycle' can be recharged a hundred, two hundred or more times - depending on depth of discharge, method of recharge, and care throughout. As for the 'technical term deep cycle referring to ni-cad', no kay ger, they were making 'deep cycle batteries' (lead plate wet cell 12v) and marketing them as such as far back as the late 1950's. Pirating a term already used only causes confusion. 'Deep Cycle' intentionally means to 'cycle deeper into discharge than is otherwise advised for comparable thinner-plate batteries'.
How do I know? I am a retired mechanical engineer who spent over 30-years designing special vehicles with advanced onboard electrical systems, especially AC/DC circuits; and spent more time fighting the ills of wet-cells and their inherent problems, than most people even in the battery industry will ever have to deal with. The company I was with was actually the first to consistently apply Peukert's Curve to determining charge capacities vs customer demand on systems (other than NASA), to ensure that the battery bank could support retail expectations.
***** might want to include the reason a starting battery turns to junk, plate deformation that generates shorts, this can also happen during overcharging and letting a battery run dry while trying to charge it. Lots of reasons for early demise of a lead acid battery. kay ger the use of deep-cycle in a ni-cad battery is a requirement while deep-cycle in a lead-acid battery it is a feature.
Mikej1592 Deep cycling of a lead acid battery is not a necessity, it's a marketing labeling gimmick! Sure there are heavy batteries and light duty, etc... all kinds of them, but the technical term "deep cycle" applies to how a battery is charged. If a battery is being damage under load, then either the load is too much for the battery or the battery is is too little for the load. Starting batteries, Deep Cycle, etc are marketing terms not technical terms,
Off topic: Once, I helped my nephew build a fence, he's a fresh out of college mechanical-engineer. He insisted to purchase the concrete at a certain big-box store across-town because he had a corporate discount there. After arriving there, I backed-up to a pallet ready-mix bags, priced at $2.99 each for a 90 lb.bag, then I wait for him to go inside to pay for what we'll need. After about a half-hour latter he comes-out pushing a cart of 60 lb. bags of the same brand of concrete but with different labeling proclaiming it "Fence Post Concrete". I asked him how much did a bag of that cost? He said $3.65 a bag, I said, there went your discount, he say's... Oh well, but it's made for fence posts!
Can I desulphate with Epsom salt, then add new battery acid ?
Acid is a deBased solution filled with electrons..
with a battery called Mega Tron did you expect it to work?
Make sure you mix a half a box of Epsom salt in distilled water and then pour it and distilled water in the battery you might want to drain the battery into a bucket but wear gloves when you do it protect yourself from battery acid
I have a Mega-Tron probably around 2003/2004 year battery that I dumped the old water/acid and used the baking soda/distilled water solution to boil it out and flushed again with distilled water. Before I dumped the old acid out it showed a reading of little over 5 volts afterwards with just distilled water showed a reading of less than 2 volts. I then mixed a solution of 8 ounces alum (food grade) to 1 gallon distilled water and used a old 6 amp battery charger from late sixty's early seventy's that still works fine but when hooked up to my alum battery experiment the meter on the charger reads 0 than jumps to 8 than back to 0 then back to 8 also battery feels warm not hot to the touch but warm. So I'm assuming this battery is junk (direct short) or I'm I missing something? Not that familiar with batteries just learning I have two other deep cycles that read around 5 volts to try and re-cover.
+hakentt Thanks for reply.
I'm replacing a 420 CCA battery with the same one which is this one :-
www.repco.com.au/en/globes-batteries-electrical/batteries/batteries-automotive/repco-extra-heavy-duty-battery-12v-420-cca-239l-x-172w-x-218h-mm-58-red/p/A9378180
The one I replaced 3 years ago,well a cell started to go bad in it & the cranking voltage got down to 8-9 volts so I bought a new one today.
Note I usually check the open circuit voltage before installing the battery & it was 12.1 volts on the brand new battery & the gravity was way down in the red on the hydrometer.
I'm not sure how old it is, I think it may have been sitting on the shelf for a while but I have it on charge overnight to bring the voltage back up !
Sulfuric acid stays acid, it does not go bad, it is a very strong corosive acid, you could dump the acid out get new cells and filter the acid into the cells, don't know how you'd filter it since only glass will contain it, there must be a way.
I thought sulfuric acid would eat through glass and could only be stored in plastic. I'll have to look more into that
U don't have to mixed it with water just add a tablespoon to each cell and charge it usually takes 2 charges
interesting video
so, you show a conductance testor and you never test specific gravity for each cell? when you say the battery is "weak," how do you know unless you use a carbon pile load testor or test the gravity? Seems like we need a crash course in battery testing!
As long as it didn't turn into a somewhat humanoid robot and try to kill him, he should be okay.
a 5 dollar voltmeter would TELL you exactly the same as that $ tester; 10.7 volts THAT is it, ONE bad cell; battery has 6 cells (2.1 volts x 6 is 12.6 ) , so 10.7 volts means ONLY FIVE cells are working;
I added salt to battery and now smelling chlorine smell 😂
that’s not chlorine, that’s the acid and hydrogen
@@KmanAuto thanks very much for reply. Any risks if I try to charge it?
Epson salt (magnesium sulfate)
not 🧂 table salt 😂
Table salt can produce chlorine when under a charge of electricity
milli-Ohms, not Ohms !
I've been researching into battery repairing and discovered a great website at Jons Mender Guide (google it if you're interested)
where you not suppose to empty the acid and filled with destilled water and epson salt solution?
Use a coffee filter. Of course it (the acid) will eventually eat the paper but not immediately. You will have time to strain out any trash. But to be honest, I would just purchase a new container of electrolyte (battery acid) from any battery dealer (granted that you can budget it. There is nothing wrong with reusing things to save money. Lord knows that I have had to many times). I have three gallons in the barn. It comes in a cardboard box of all things. Of course inside the cardboard box is a thick plastic bladder that actually contains the acid. from the bladder is a small rubber hose with an old fashioned pinch valve to control or stop the acid flow from the battery. Wear old clothes, rubber gloves if you have them and of course safety goggles. Battery acid in the eyes hurts a lot. I know from experience.
The battery resistance is not measured in Ohms. It is measured in MILLIOHMS!!!
Why not just invest in Military grade batteries? They have some you just jump with a resistor when the voltage drops and they get a full charge!
Umm.. Military grade batteries = insanely expensive.
Jump with a resister? I think you need to do some reading up. Resistors will DRAIN power, not charge.
I found the ad in a magazine and they are dry cell and were in rv magazine and it said clearly if voltage dropped below 12 you would simply jump it with a resistor and you'd get the full voltage instantly. I do know that sounds funny, but these were unlabeled green batteries that military uses in all vehicles and they don't have time to charge a low battery, so something as quick as this is a requirement, these batteries were also said to last 10-15 years or more. I will do more looking online to find them.
+LuxorVan The winding's in an engine starter are basically resistors. So if I use one of those and my battery's dead I can just turn the key and voila? Trust me dude, too good to be true.
All I know it claimed that it had two terminals you touched a resistor to, it would renew the voltage. They were in the back of an RV magazine years ago! I was only stating their claims! Probably like 1999-2001! It obviously wouldn't work on normal batteries! But if it were available they would be a great investments!
LuxorVan The back pages of any magazine are filled with crap man. The technology may exist though and you get a plus in my book for your enthusiasm. Cannot and will not gain a charge from applying a load (resistor) to a battery. The least it could do is desulphate the lead plates in the battery, still needing charging before operational (kinda what this video is covering). Remembering stuff from '99 gains you the credit of a Human Being. Keep it up mate (mostly everyone else cares about nothing) :)
You need to desolve the epsom salt in the water first . Don't take his advice

No....... just no.
We all know that you cannot desulphate a dead battery let alone a dead cell, so why do you insist on wasting our time?
