- Absorbed Glass Mat (AGM) batteries get to a point where they will not charge because they are below 8V - 5V, be that a Northstar, Odyssey, Optima, Deka, or any other brand of AGM battery.
AGM batteries differ from flooded lead acid batteries in that the electrolyte is held in the glass mats, as opposed to freely flooding the plates. Very thin glass fibers are woven into a mat to increase surface area enough to hold sufficient electrolyte on the cells for their lifetime. The fibers that compose the fine glass mat do not absorb nor are they affected by the acidic electrolyte. These mats are wrung out 2-5% after being soaked in acids, prior to manufacture completion and sealing.
The plates in an AGM battery may be any shape. Some are flat, others are bent or rolled. AGM batteries, both deep cycle and starting, are built in a rectangular case to BCI battery code specifications.
Many modern motorcycles and ATVs on the market use AGM batteries to reduce likelihood of acid spilling during cornering, vibration, or after accidents, and for packaging reasons. The lighter, smaller battery can be installed at an odd angle if needed for the design of the motorcycle. Due to the higher manufacturing costs compared with flooded lead-acid batteries, AGM batteries are currently used on premium vehicles. As vehicles become heavier and equipped with more electronic devices such as navigation, stability control, and premium stereos, AGM batteries are being employed to lower vehicle weight and provide better electrical reliability compared with flooded lead-acid batteries.
5 series BMWs from March 2007 incorporate AGM batteries in conjunction with devices for recovering brake energy using regenerative braking and computer control to ensure the alternator charges the battery when the car is decelerating. Vehicles used in auto racing may use AGM batteries due to their vibration resistance.
Deep-cycle AGMs are also commonly used in off grid solar power and wind power installations as an energy storage bank and in large-scale amateur robotics, such as the FIRST and IGVC competitions.
AGM batteries are routinely chosen for remote sensors such as ice monitoring stations in the Arctic. AGM batteries, due to their lack of free electrolyte, will not crack and leak in these cold environments.
VRLA batteries are used extensively in power wheelchairs, as the extremely low gas and acid output makes them much safer for indoor use. VRLA batteries are also used in the UPS (uninterruptible power supply) as a back up when the electrical power goes off.
VRLA batteries are also the standard power source in sailplanes, due to their ability to withstand a variety of flight attitudes and a relatively large ambient temperature range with no adverse effects. However, charging regimes must be adapted with varying temperature.[8] Both AGM and Gel cells are commonly used in powered aerobatic aircraft, for the same reasons.[citation needed]
AGM and Gell-cell batteries are also used for recreational marine purposes, with AGM being more commonly available. AGM deep-cycle marine batteries are offered by a number of suppliers. They typically are favored for their low maintenance and spill-proof quality, although generally considered a less cost effective solution relative to traditional flooded cells.

*This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, **batery.repair** and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*
NoCo battery repair works on most batteries that are 'restorable', ie; the lead plates weren't dry or neglected. I restored a cheap 9 year old Everstart 275CA lawn tractor battery that at first read 3 volts but after 2 weeks of intermittent battery repair mode it took a full charge and the load test read more than 200CCA and held it! Ran a repair few more times and it now works great. Note this battery never dried at all, all cells remained flooded.
My Interstate car battery OTOH had 2 cells that had exposed plates and even after topping off and repair mode run all weekend only 1 cell came back full the other was dead.
In all I restored 3 of 4 batteries using repair mode and by repair they hold a charge and crank over motors without worry. You'll rarely get full CCA new ratings back but that's to be expected.
Great training for me. Not only did he go through many different procedures to try to bring back a bad battery but he also showed how to use the volt meter and a battery load tester and why he needed to use both in this case. Also using a regular battery tester to get the bad battery up to a higher voltage was very important to see.
+perkeap09 glad it helped you out.
Hi. Its incorrect to say that AGMs wont take charge if they are below 8V. Ive charged an AGM that only had 5 Volts no problem. The problem is not the battery. The problem is the charger. Lot of chargers come with a cutoff to stop users from charging batteries that are degraded to the point of short circuit. If you use very old chargers (no cutoff) they will charge and the battery will take charge. Problem is not limited to AGMs btw
What amazes me is that when you go to Walmart or Autozone to buy a new battery and the battery you buy has been sitting on the store shelves for 6 months or more and you actually think that a battery that is already 6 months old is really brand new.
That’s why I always charge a née battery on my Noco Genius charger before installing it into the vehicle, no matter where I bought it from!
I have had a lot of problems with the newer Optima batteries. No matter what tricks I try, they won't accept a charge when they have gone dead. I have tried 2 batteries- multiple chargers including trickle chargers with no luck. No more Optima batteries!
Try parrallel batteries hookup with traditional charger on the non AGM battery. Worked for me!
i just fixed my old car battery today, it ha been sitting in my shop on the floor for 5 years
I am having the same problem man but with a Optima Redtop battery. Went on vacay for a month, came back that thing was gone. Tried to charge it back up and it did the same funky thing as the yellowtop in your video man. I'll see if I can get it replaced somehow.
Optima quality nose dived since moving production to Mexico. Im not the only one to notice this as well. Co owner of battery.shop told me they quit carrying Optima due to the quality nosedive i noticed. Junk now. I wudn buy one but if free id take and play around try to revive.
@@dw4940 Mexico production is NOT THE issue. Issue comes from interstate buying the company.
Probably has high internal resistance from sulfation. Need to desulfate or it won't put out the amps.
Old dumb 6 amp charger will charge those batteries if they can be charged. Might start at very low amps. (like .5) and gradually increase to 6 amps over hours. Then charge at gradually reducing amps over many hours. The 6 amp charger charges at less than 6 amps when a good battery is pushing back at more than 12.6 volts. Will usually "taper" to less than 1 amp. Bigger (high amp.) and "starter" chargers such as on wheels and found in garages can boil and damage a battery or even damage car electrical systems if connected to a battery that is still hooked up to the car cables.
The dumb charger is not safe to be left connected unsupervised for a long time to a good battery because it will eventually probably exceed 15 volts at less than .5 amps charging which might damage the battery.
Would be good if they made a charger with a built in accurate voltmeter and ability to program it to cut off at a particular voltage and open the circuit so as not to allow the battery to discharge back through the now shut down charger. Say a voltage of about 14.5 which is about the maximum you want to take an (healthy) Odyssey battery up to on charge.
CTEK 5.0 is the ticket for AGM (as well as traditional) batteries. I just finished running the recond on a 6 yr old AGM battery in my BMW. This battery had been on a CTEK regular mode which goes into maintenance mode after initial charge for more than a month and a half. Battery is rated at 800CCA. Testing with CTEK battery tester it tested @675CCA straight off the charger. After Running CTEK 5.0 AGM/Recond it tests @925CCA. What more could you ask for?
Yeah that battery shot considering even though it's showing there is voltage on it the voltage that's on that battery it might be a slightly dead cell but then again you try putting a traditional charger on it that's probably your best bet not the genius charger cuz the genius charger may tell you battery is good sometimes it may not may tell you the battery is bad so what do you have to go on?
don't matter that it will charge problem being one of the cells inside the battery has a short that causes it to drain the rest of the battery too quickly
Might add that when connected up in a car,the car can be taking power out of the battery even when the key is turned off and removed from the car even if the dome light isn't on--I suspect as much as an amp-hour drained from the battery every day-the battery stays charged much longer if the cable is disconnected
Battery NON restoration - won't get that ten minutes back.
Thanks. As soon as he checked the "bad" battery, I checked the comments.
I've learned something sir, is you glass half empty or half full?
Kudos for the Video! Forgive me for butting in, I would love your opinion. Have you heard the talk about - Rozardner Powerful Battery Reality (just google it)? It is an awesome exclusive guide for learning how to recondition an old battery without the hard work. Ive heard some incredible things about it and my BF after a lifetime of fighting got excellent success with it.
Good job making the video, it was very informative. I am very impressed with the Noco Genius 5 and 10 chargers and the repair mode, and force mode they have to charge a battery that is below 1 volt.
What is your opinion on battery desulfators for maintaining a battery? I use a Pulse Tech PowerPulse passive desulfator, they claim to have a patented frequency they use to desulfate batteries and can extend the life of a battery up to three times, I have been using it on my BMW battery for the past three years and never have any issue's starting even though I only drive about 25 miles per week.
Why didnt you do an equalize charge to desulfite the plates then try an normal charge?
+Jack neff looking back I should of tried too
I've had a problem with the optima batteries shorting out even less than a year old
Can you use a battery that is in a car or truck as the host?
i have an 8 year old battery yellow optima trying to fix it any recommendations?
Using another battery in parallel didn't do anything for my AGM battery. It would show 12v and after removing cables, it's back to 6.4v regardless of how long I leave it connected to host battery.
Well sometimes AGM’s die and they need to be laid to rest. RIP AGM.
@@bundysgarage I got a good laugh out of this reply in regards to AGM batteries going dead for good!!! But it's true once they are really dead then there's no sense in trying to bring them back to life!!! Just lay them to rest for good and buy yourself a new one!!! 😂😂😂
Get a high tech battery tester like the CTEK, they don't have to put a high load on the battery.
@ 10:43--might need more time if that is a low amp. charger--if the battery is storing the charge and holding it the voltage will go up to over 13 volts. Probably eventually to over 14 volts,if the battery isn't getting too warm probably no great danger of explosion
At the end if that battery were any good it would have been charging at 14.5 volts or even higher,and when disconnected from the charger after an hour or so would have showed 12.6 volts or a little higher open circuit.
My yellowtop battery is reading 11.18 on my car...will that regular battery charger work
Put it in a freezer.. take it out 2 secnd day.. then charge it slow .. till the next day.. it should come up .. hoop u get progress ..
Interesting concept
my agm scooter battery looses charge way too fast will go from over 13 volts fully charged to around 12.8 volts just from sitting not in the bike so its not parasitic drain before it would hold 13 volts charge for months any hope or is it time for new one. I keep it inside because I've had them stolen sad but true. I did drain it once trying to start the bike so maybe that killed it.
So if you bought an expensive battery and died after 3mos. You lost all that money ! (where do you bring it 4 replacement if bought at Amazon an odyssey agm?)
That Schumacher bat charger is faulty if it is the standard type batt charger it should have gone over 14.5 V
Great vid though
You can use a jump pack instead of using a battery
What about the Electrolyte?? Maybe it's dry!!!
Funny thing - stumbled upon the EXACT same technique just last night. BIGCRANK M/C batteries ROCK!
(and if makes you feel better I only watched the first 2 minutes)
Bought a Stinger SPP 2250 off of FB market. I have had it on a microprocessor charger for about 16 hours. It test good and works ECT but the charger never reaches 100 percent. Should I charge it for a day or 2? Its a HUGE battery and I would really like it to work out lol
Stinger batteries are almost impossible to get to good capacity once they have been drained down. They suck honestly…. I used to sell them and I tried running them in several cars.
@@caseytbss I was able to restore it by charging overnight with a analog charger then I used the microcharger for a day and it seems to be doing pretty good. I only paid $150 for it so if it last a year I'm still happy
My agm reads 11.7v with a +\- 10% of 100% charge. After charging the battery it drops back to 10% after 24 hours or less. Kinetic 2400d is the battery, had it since 09'. Any tips?
50ml distilled water per cell, 24 hours rest, and then charge with 6 amps current.
Stamo Hristov .......thanks, but i found shorted cells too. Looks nasty inside
Every shorted cell looks nasty :-D
In my experience resurrecting a bad battery is impossible, I would have to go Pakistani mode to rebuild it. I rather buy a new one!!!!
Aside from EZ battery recondition scam, you can put the Optima battery on a negative pulse reconditioning charger for a week or two and see results then. In Bulgaria we have ACCUTONIC.
Waste of time. Rambling ..... Rambling ..... Rambling ......................
thats not cherrioo matey
will this work with motorcycle battarys
I had a dewalt charger, desulfate capable. Was able to bring back a bunch of batteries and had fun accomplishing that. Optima are total garbage now. Ever since moving their operation to Mexico. I wudn buy one. Ive always had good luck with odyssey. Cept when had several bad alternators brand new from Napa but key being made in China.
Question I have a XS sealed glass matted battery is it possible for that type of battery to lose fluid?
They will no leak any acid. If you overcharge them they will gas 14.4 is the safe zone. Charge voltage can also depend on temperature of battery. How do I know this cause I have a xs power d3400 5 years old. Charge with either my hf1215 or my psc15. I perfer to charge my battery only with xs power charger.
They can lose their fluid via gassing if overcharged.
Try changing the optima at 24v with 2 car batteries
What good is that going to do besides potentially create an explosion?
@@caseytbss worked for me many times
Ka-- Boom!
This isn't restoration. Just showing how to kick start the charging process for a deeply discharged agm.
Which is defined as restoration, dumbass. Opps common core.victim. my bad
how long will that optima old a good charge on normal driving after reviving it like that?
+Philip Sanzari hopefully for a long time
haha you moved the battery and it released acid from the mats and showed a better charge that happens on battery's like that.
I guess my question is....what does non spillable sla battery mean if thats all it says on the battery.
SLA= Silicone Lead Acid a great combination I have them in my Vectrix V2 Electric Scooter
Its not silicone lol
It's Sealed Lead Acid - meaning no access to the cell caps to add water.
Repeatedly AAA comes and uses a discharged battery with that meter that sais it's not restorable.....they are clueless or lying to don't know how to read the test....the tester doesn't work on a battery unless it's fully charged? That must be why when I charge my batteries and use them against their advice they actually work again......
Another issue is I think batteries can get used up but I don't know the technology on that...this assumes there's restoration in battery chargers alone.....I think they are all fully restorable and the companies need to be totally tracked on what exactly they do with all those old batteries....Add electrolytes, repackage, resell.......is my suspicion.
I also wonder if the tests work on a battery that just sat and sat....I'm hearing you can't restore a battery that sat on concrete....but nobody can explain why....I have an Optima I never used but it's a 2010....brand new....but discharged deeply....
Another thing is why....oh why just you don't put them in a car to charge them up? People say it can destroy the alternator but I don't know.....would like to....
You should cycle it multiple times
9:20 those batteries are really poor. its very very common
When you are load testing the battery if it drops to zero immediately let off the hydrogen gas can set off an explosion inside the battery
Ampmeter, you mean voltmeter...
It's actually called a 'Multi Meter'.
15 minutes if my life totally wasted
Question......are all non spillable sla batteries agm or gel?......how do i know if my 12v sla battery is wet flooded or agm/gel?
AGM and Gel will have a label. Flooded will not mention the older technology.
Optima batteries are way overpriced low quality Mexican junk... They don't last even half as long as they use to.
Mexican Junk!!!! I use to tell everyone to buy them. My first one lasted 9 years! I spoke to one of their manufacturer's rep's and he said that they are told to tell the public that the Optima batteries are made "South of Loredo". Loredo, Texas which sits on the border of the USA and Mexico. Google, Lordeo, Texas. If you are looking for a great AGM battery look at Northstar AGM or Odyssey AGM batteries.
Appreciate Video! Apologies for chiming in, I would love your thoughts. Have you heard about - Rozardner Powerful Battery Reality (erm, check it on google should be there)? It is an awesome one off product for learning how to recondition an old battery without the normal expense. Ive heard some decent things about it and my old buddy Taylor at last got great results with it.
NOPE! never heard of it. People are always trying to post stuff like this to this video. Is it some type of multiple level marketing thing you guys are trying to push? Really, what is it?
Hows it work when agm are sealed as are a.lot of wet old style batteries?
Anyone trying to sell you information on how to recondition batteries is a scam artist. It's not hard to find decent information for free these days. This actually used to be common knowledge among handymen. It took me ten minutes to find out how to restore my car battery. Pour out the old electrolyte, add in some baking soda and water to loosen up the sulfate, drain and clean out the cells, then fill it with distilled water and epsom salt, slow charge overnight and boom, Bob's your uncle.
I'm just here to find out if the same process can be used on an AGM SLA battery for my cordless mower.
I have spent months researching into battery repairing and discovered a fantastic resource at Jons mender guide (google it if you are interested)
