beautiful yard.....enjoy .... Jay Fox
My dad has a battery charger that he bought at Sears over 30 years ago and we still use it til this day.
I still have a Sears charger too bought back in the early 80s. Plus a 40 year old Craftsman 1.5 ton hydraulic jack that I still use regularly. 😎
Old stuff worked.
Well, that’s why Sears is out of business because their stuffs last forever.
My dad ran over his Sears charger in the 70s. Mangled the metal housing. He continued using it for the next 20 years. Before we took away his keys, he left the headlights on with increasing frequency.
I wonder if the cheap electronic charger is effective as a trickle charger for my truck which is used seasonally.
I love all of my White brothers and sisters.
DSR is the logo for Don Schumacher Racing. Don Schumacher, Connie Kalitta & John Force have pretty much kept the NHRA going for the last 30+ years. Sad that Don passed away last December. Schumacher Electric is a great company with quality products.
From their homepage:"With an owned, vertically integrated global supply chain, including plants in China, Mexico, and Belgium,..." Wonder where the one Scotty was promoting made? I bet it wasn't in America.
Reviews I've read on BYDs electric car have said it's great. If you could, test the 16k model.
15 years and still running their trickle chargers
I bought one of their chargers, a small one, about thirty or so years ago -- all analog. It gave very good service for about 20 years, and when it went kaput, I decided to get another Shumacher because of the the good service. All I could find was digital, with LED lights, and micro processor controlled. So that was what I bought. The thing was a total piece of crap. That's when I discovered Associated--all American made and all analog. I will NEVER buy another Shumacher product again ever. YMMV
I've got a Schumacher battery load tester. No digital crapola, just some resistive wires that put a real load (not simulated) on the battery and a needle gauge to view the voltage drop. Had a mystery battery that digital testers said was ok. Hooked it up to the Schumacher and it fell flat on its face immediately. Software algorithms are no substitute for reality.
Check voltage, as long as its not that low, the best way to charge a typical battery is a trickle charger. It'll charge slow, like it'll take 48 hours. But its the best way to bring an older battery back to life and it not die right away.
Trickle charging is unnecessarily slow for most of the charge cycle. Optimal charging of lead-acid batteries has 3 phases:
*Bulk Charge* -- charge at the battery's acceptance rate until about 80% charged.
*Absorption charge* -- steady voltage while the amperage is gradually reduced, until about 90% charged
*Float charge* - voltage begins to taper until it reaches the battery's natural voltage level. At this point it reaches the "trickle charge" state, which can be maintained indefinitely.
If a battery is in such bad condition that it can't withstand the 3-phase charge it's not worth bothering with. People fart around with epsom salts and "desulphation" gadgetry but it's almost always a waste of time.
Got it Scotty !
Buy the heaviest charger .
Thanks mate !
I bought a Sears rolling battery charger/starter in the early 80s to start my CJ7s. Still use it today and I paid the outrageous price of $65 back then. It has one rocker switch between start and charge and two volt meters….and that’s it. Best purchase ever made hands down. Of course I only drive old school Jeeps and single cab trucks so I’ll probably will it to another who does the same.
Oh God, scotty is mad as hell ! Run everybody run and don't look back 😂
Some say his car was "destroyed". It's a lie but they say it anyway, for clicks.
At your suggestion, I purchased a Tower Top 12v 2,10,25 A charger Nov 2021. I have used it several times since then and it has worked perfectly since then. I'm 75 now and worked one summer @ a Chevron station in Elko, NV and learned many of the skills you share and greatly appreciate your honesty and advice. May God continue to bless you and your family for many years to come. Thank you.
One of my favorite channels. Scotty is amazing, and never boring. Thanks for sharing your wealth of info.
By design some chargers do not charge below a set voltage, assuming battery is damaged and may expand/leak if charge attempted. The work around is a quick surface charge from another battery, then charger will take over from there.
Or buy a battery charger that has a bypass feature or is designed to charge very low voltage batteries. The big problem is making sure of the batteries voltage. A 12V battery with a bad cell can outgas hydrogen if it's charged like a 12V fully functional battery. So, the electronics will charge it as a 6v. The second, third or fourth time, it might charge properly. There's also a crossover between 6V and 12V as well as 12V and 24V where the charger cannot distinguish one from the other. So, in software, rules are made based on how fast the voltage increases during charge. Your quick work around can possible cause problems if the battery you're trying to charge is really a bad battery. A spare battery probably costs more than getting a good charger, plus you need to maintain it.
I'll take made in Vietnam any day over made in china
You go right ahead!
Still Chinese: all the components are made in China, ship to Vietnam and assemble in Chinese factories in Vietnam. 🤩🤩
How about Made in America? Associated's chargers are all American made.
Imagine how steam punk Scotty would be if this were 1904. Wit those same glasses
You have been showing us vehicles catching fire (EV's) & tell us not to park them in our garages why would we use lithium batteries in our vehicles that could potentially catch fire ?
So how did the stupid device destroy your car and why are you mad as hell? I guess I missed that part. Or do you outsource your bylines?
New here?
You clearly don’t get the joke lol new viewer ?
You came here to watch only scotty is mad as he'll.
Ha ha, not new. Been watching for years.
You should mention that the good changer you show are UL listed as well. Great video
A car battery at 12 volts is actually only at 50% charge. A Full charge is 12.6 volts. Car batteries (typically) have six 2.1 volt cells. Just so ya know.
Oh yeah prove it
huh 😂😂 have you not taken a volt meter to the terminals after letting it sit on a charger 😂😂@@TheNaturalGamer1
13.8 volts
14.1 to 14.6 I think
Wrong! 12v is flat. A topped up lead-acid one is 12,6~12,8 depending on chemistry. These values is AFTER the battery has been sitting with no load (or charge) for 24 hrs. Regards from an educated and experienced pro in that department.
Daily sanity check. thank you Scotty!!!
Scotty is always right. Get the best tools to fix your car. So it will last long.
My father was an " Head Mechanic " in a Chevy Dealership in the 1970s! Back then people would spend $ on anything but a battery! Many problems were a crap battery even back then!
Jay Leno really likes the CTEK chargers. Just be aware that if you choose the option to "recondition" an old battery, it will pulse 16Volts into the system. While every company says there is no need to unhook or remove the battery from the vehicle, you need to make sure every item in it can handle 16volts.
He'd know with all those cars he has
15v + absolutely kills batteries, but I suppose the Pulse might be OK? I've killed more batteries than anyone I know 😂
@Vmaxfodder😅
Great advice! Check your owner’s manual for recharging instructions! One of my cars requires disconnecting the negative ground to recharge. I also blew diodes on another car’s alternator when I just hooked up the + and - terminals to recharge. A check with a voltmeter showed it ( Schumacher) was peaking out at 16.4 Volts! Now I remove batteries to recharge and jump with a recharged 12V battery to be safe! I still use a resistor type battery checker. This might require resetting computer…good luck to all, what works for me might not work for you!
@@Vmaxfodder Yep, the 16V pulse is not steady, just momentary and enough to break up the sulfides on the plates inside. It just needs that extra voltage to break them away. The fear is very sensitive electronics in the car may not be able to handle even a momentary 16V.
Scotty, how was I ever able to go through life without your advice! (Imagine me swaying back and forth and waving my hands in the air, while I say this!) 🥳😜🎉🎉🤩
I still use the one my dad bought in the 70’s. Beat to hell but still works great.
Scoty , I thought the whole idea behind bicycle riding was exercise. How are you going to get any exercise on those electric bikes ? Next thing you know I'll see a Tesla in your driveway !
First off, thank you for all of the great information and tips that you provide on the daily!
Now, can you share what the foldable e-bikes that both you and your wife like so much are, and maybe where you got them?
I watched this one, and have been having some bad electrical problems on our 05 Buick Rendezvous, I replaced the battery, and it's all good again! THANKS for the good advice! (BTW this thing is a nightmare to work on, no room!)
Which device destroyed your car?
The cheap ones... who did not the job snd the car did not start... 😂
@@peterpanini96 So by "destroyed" he means: didn't charge the battery but a better one did?
@@HOSPlTALLER yes
@@robertthomas1569 AMAZIN! /Jesse Lee Peterson.
@@snupermoto723 another bewildered newbie.
Mr. Kilmer, thank you for all your help in teaching me a lot. God bless you. I want to ask you about my new side job of fixing cars. I just started, and I don't have a car scanner yet.
So you think your old Toyota alternator is made to charge a lithium battery...uuummm
He will be mad as hell when that cheap chinese lithium car battery burns down his beloved Toyota Matrix, he slags off most chinese products as cheap junk but when he is given something free he tells everyone how good it is, Scotty is easily bought off.
The old Toyota alternator will easily charge a lithium battery, just not all the way. Lithium batteries are over 14volts while lead acid and agm are around 13.
It can be done by doing an adaptation at least on voswagens.. 😂
Hey Scotty, thnx. 4 letting us know 'it's made in Vietnam, x2 it's made ---- well,we get the 💡 😂😂😂
I suspect the electronics in the lithium battery will adapt the charging voltage to the lithium cells - easily done with buck-boost converter technology - and, after charging, allow a discharge process as per any other battery.
Scotty the pulse repair is excellent, I ve save several batteries using the pulse repair, dude it works, But disconect the battery every time.
Great education on battery chargers thanks.
Thanks Scotty good info !
I remember we had one of those in the 90s. It didn't even have digital reader - it was all analog.
It was purchased at a Flea Market.
The shoemaker battery charger you have is owned by Don Schumacher racing which is a Drag Schumacher electric which makes it all the chargers and everything electric you need
Thanks Scotty, and tell us more about charging LiPoFe and how long for and how many volts please
I have 2 Schumachers, one heavy old one and a newer super lightweight which also works OK and has a setting for AGM. The heavy old one will happily discharge your battery if you hook it up backwards, works fine otherwise and has a jump start setting. Also have a Battery Minder which can charge a battery, but it is best to hook it up when you don't need a charge.
All the transformer based Schumacher chargers will discharge a battery if reverse connected. There is a bimetal safety breaker on the output clamps, when it heats up from too much current, it will open. When it cools down, it will close. The UL test on this is 7 continuous hours minimum using a very large fully charged new battery, >100Ah.
I picked up an old charger with no electronics on eBay and its still works great after 20 yrs
scotty recommended towertop chargers and have been using it for years and does a great job. charges at low amps and reconditions batteries.
Thanks Scotty !
😇🙏👍
Wouldn’t park that electric bike in your garage. Pretty risky!
I have a Juiced bike with quality batteries, I it's 3 years old. I rode it the first two years 37 miles a day 7 days a week. I used it yesterday. batteries perfect. it can do 30 mph in offroad mode. It has 2 batteries. The key here is charge slow, drain slow if you need fast and long lasting with no explosions. So, decrease battery volts and increase amps. connect in parallel several quality batteries. don't be cheap and get more copper.
@@productcheck That makes no sense whatsoever.
Electric car?
I bought a cheap charger recently. It was £8 here across the pond. Hooked it up to my dead flat battery. It worked fine fully charging the battery in a few hours.
I'm gonna go out on a limb and guess that being Scotty's wife likely has some challenges... Just sayin'
First vid: "This woman DESTROYED my life!"
Second vid: "Why this woman SAVED my life!"
Well, Mrs. Scotty always knows where her husband is, she never has to fix anything, they both like road trips, she gets to try out new toys, their kid still comes around and her entertaining Hollywood husband is a comedian who makes everybody happy. What you see is what you get with Scotty. Great human being.
You can be right or, happy...
Didn't Scotty say this, too, one time? He can fix just about anything...but stupid, of course (per my new Scotty-approved T-shirt with chortling horse). 🤔😀💙 @@islandaerial3414
Yep !!
Try a volt meter
I have a 30yr old 10A Schumacher battery charger with an analog dial and it's still going strong as the only car charger I've ever needed. Except for a Battery Minder for my motorcycle battery. Hey, what's Scotty doing with a garage full of e-bikes? Scotty talks a mean talk of not keeping them indoors if you own one, and find out he's a collector of them! Has Scotty taken up politics, I'm hearing double talk... HA!
What setting do I use to charge my lawn tractor battery with my Chinese charger. The car symbol or motorcycle symbol??
I got two Schwinns made in the 1950s-1970's and they sure ain't electric! Chicago, USA!
I have been very happy with the NOCO GENIUS10, 10A Smart Car Battery Charger. Has a lot of good features. About $99 on Amz.
Same. We have 1 in each car and truck.
Great video
Albeit pricey, I still really love my Ariel Rider Grizzly. Dual battery AND dual motor. 35mph+ when unlocked... Solid built, heavy as all get-out (~100lbs with both batteries), but I've laid it down and ate pavement a few times with it (sand patches on the street in Tucson) and nothing broke.
So, how does your alternator think of the New battery? Lithium. as you said, requires Slightly different charging.
I charge a 12v Lithium kayak battery with a charger that was manufactured before lithium batteries came around. No issues so far.
@@SqueaksUofAi heard old chargers can damage a 12V lifepo4 after its charged up and left on float charge too long.
@@MonstroLab I’ll try to remember to come back here once she goes. Wish me luck
@@SqueaksUofA i think you should be fine as long as you remember to remove before it goes to float mode. but id ask a pro and wouldn't hurt to charge outside away from your house. (in case of fire ) good luck!
The Lead-Acid replacement Lithium batteries use LiFePO4, so they can handle more abuse than the Lithium Ion types. They are rated 3.2VDC per cell nominal and charge up to 3.7VDC. These lithium battery types have battery management circuits inside the plastic housing. Internally the batteries are usually smaller than the housing and the battery package is lighter than lead-acid types. Lithium has a higher energy density compared to lead-acid. The management circuit will monitor the charge and discharge of the LiFePO4 batteries, so they are not over or under charged. It also monitors the temperature of the cells and will shut down if the temperature goes too high. A 12VDC battery will have 4 LiFePO4 cells connected in series inside the battery housing to get the battery voltage (12.8VDC). Internally, they will also be connected in parallel to reach the desired capacity. So, they are Series-Paralleled connected internally. So, it doesn't matter what voltage the alternator puts out, it won't harm the lithium battery.
I had a name brand battery maintainer for years. My lawn mower battery was going dead, so I replaced it, and it went dead. The charger was actually discharging the battery instead of charging it.
I used to design battery chargers, mostly for AGM batteries in mobility scooters and wheelchairs. We had dozens of charging regimes supplied by the battery makers, defining absorption stage voltage, time to linger before dropping to float voltage, float voltage etc. They wete always tweaking the battery chemistry and re-issuing a revised charge regime. If we supplied a charger we had to program for the exact battery it would be used with. Auto chargers are simpler because it's not cyclic use. With a cheap charger I wouldn't leave it on charge without checking the voltage with a meter. A cheap charger can allow the battery voltage to rise excessively to where it starts out-gassing.
I have one very old Sears charger/maintainer and three newer tricklers that keep my batteries topped up. They have never failed. The three small tricklers are Schumaker. I don't know who made the Sears charger - probably Schumaker.
If you have to use a special battery charger for lithium, Won't the cars charging system cause harm? how is it different than an normal battery charger? You should make a video on that to explain it. Thanks
The reason the specific charger is that lithium charging curves are different from lead-acid. Lead-acid voltage starts low and increases as it comes up to capacity. Lithium will go to 12.8V immediately and just stay there. So, a lead-acid battery charger will think the lithium battery is bad and stop charging. Either a charger with a special lithium charge function or a separate lithium battery charger are required. The alternator is fine, since it is just a voltage source and not really a charger. When the engine is running, it just outputs a voltage to whatever battery you have attached and won't stop until you turn off the engine.
3:12 Drag racing in the background. 😂
I have a very old Schmacher charger, not a high speed charger. Simple to use. Has never given me any problems.
The light unit uses a switch mode power supply to eliminate the heavy transformer. The old transformer is simple and less likely to fail, but costs more.
The SMPS charger will allow a better charge, it has very low ripple current. A linear (transformer based) charger works off 60Hz (NA) and after rectification is 120Hz ripple. Many use SCRs to control the output current, so at lower currents the higher the ripple current. Basically, you have AC riding on the DC. The AC heats up the battery, doesn't charge it but does cause it to charge less (because of heating) and sulfate easier. So, yes, a Linear design will last longer, it isn't without it's problems. Also, an SMPS has a transformer too, just a lot smaller due to the high frequency, a lot easier to manufacture and a lot cheaper to make. The weak part of SMPS is the rail electrolytic caps. A good design will give you a good 10 years. A cheap design might get you 3 years, but some only year (like Home Depot CFL bulbs, super cheap and the caps burned out).
Scotty you say you need a li-on specific charger for Li-on batteries but correct me if wrong, but you can put them in your car in place of lead-acid battery?.
The lead-acid replacement lithium is not lithium ion. These are LiFePO4 and are a lot more stable, but have much less capacity. They use Li-Ion in EV cars because they want mileage. The reason the specific charger is that lithium charging curves are different from lead-acid. Lead-acid voltage starts low and increases as it comes up to capacity. Lithium will go to 12.8V immediately and just stay there. So, a lead-acid battery charger will think the lithium battery is bad and stop charging. Either a charger with a special lithium charge function or a separate lithium battery charger are required.
Does that test car have a lithium charge system?
Battery chargers that are dumb or just output 12v anyways are great for flat batteries albeit you have to keep eye with volt meter to make sure doesn't over charge the battery.
Wouldn’t use an auto lithium battery, too much fire risk!
if the alternator can charge the lithium battery why does a charger need too be so specically built
Different chemistry batteries require different charging routines. Constant current, constant voltage, charge levels, charge hold, cell balancing etc. Manufacturers publish charts for the recommended charging process and simple battery chargers rarely meet the required spec and can DAMAGE your battery. The more expensive chargers have computer-controlled charging circuitry that allows you to select the type being used. Ordinary car alternators are made for lead-acid charging only and will damage any other type of chemistry. You CAN charge a lithium using a car alternator but don't expect it to survive!
@@kellyeye7224What about AGM? I have one and it seems fine but I think it might have done something because my lights flicker now.
The regulator is the device that inputs regulated DC current to the battery. The Alternator produces 3 phase AC power which is rectified to DC through the rectifier and then regulated per the battery type & charge specs installed by the manufacturer.
The lithium batteries replacing the lead-acid have a battery management circuitry built in. The alternator will work fine, because it is just a voltage source. A charger with electronics, probably a micro, may have problems because the battery doesn't charge like a lead-acid battery. A lead-acid battery is considered dead at 10.2V (FLA) or 10.5V (SLA). The voltage will increase on a lead-acid while charging and go to 16V (FLA), 15.4V (AGM [SLA]) or 14.8V (GEL [SLA]). A lithium battery, on the other hand, will jump right up to about 12.8V and stay there. The dI/dt is much longer for a lead acid battery than it is for a lithium battery, which is like a blip. So, a lead-acid battery charger might think the battery is sulfated and stop charging. A lithium feature or a separate lithium charger will have electronics designed for this.
I've been using OPTINATE 6 for years and I am actually happy with it, decent unit.
My little light weight one worked great for my battery.
I have a 10 amp 6/12 charger that I bought when I got my first car in 1972. Things wieghs about 10 lbs.
DSR stands for Don Shumacher Racing.
Scotty’
I’m happily driving a Dodge Caravan in Canada. She’s a 2010 and runs sound. Powered by the original Mopar battery. Under 200 000 kms.
Scotty if you place a Lithium-ION battery in a car you need to also replace the voltage regulator to properly charge the LI battery, or it will be ruined because it is being charged correctly.
Scotty.....start doing reviews on tools, oil, cars, tires and such! AATW
Scotty talk common sense. Some people buy an item one day and give it a review few days later. They know nothing.
I love my OptiMATE 7 saver/maintainer
Okay, so *which* car got destroyed? by a charger?
None!
Scotty lied to you and all of us....again.
Are most car's charging systems compatible with lihium ion batteries?
No.
think you suggested the dewalt in a previous video, that is why I bought it
I use the Dewalt to charge up a battery in a car that I have sit for extended periods of time. Works great - I agree it is a cheap/inexpensive charger but it does work for my needs. If I don't use it, you clearly tell on start the battery is low (6.4L V8).
I got a 10 amp from JC Penny auto (wow that was a long time ago) works to this day and I beat the life out of it
In able to charge a battery a certain voltage is needed, if it's flat connect in parallel another battery and then the charger, after 4 hours disconnect the other battery and then connect the charger to the car's battery. It has worked all this years.
OK, yes batteries need special charging depending upon the technology for the cells within them. Saying that cars recharge their batteries with the on board alternator based system. They are set for the standard lead/acid batteries. They have zero intelligence, just put out the 13.8 to 14 Vdc to recharge the battery. So, your Li battery (and gel) has to tolerate that type of charging system. As to external chargers, all they should be required to do is exactly what the car's normal system will do.
How does the car system know it is a Lithium battery? It doesn't have a special mode for Lithium.
I’ve had the automatic electronic battery chargers guess 6volts when the battery is a 12v. So it would charge to 6v. And say complete even the Schumacher!
Yes, this can happen when a battery is deep discharged, such as below 8 volts. The charger will usually put out a small current to monitor battery voltage. If a battery is sulfated, the voltage will jump up. However, a good battery will take a long time to go up in voltage, so the electronics are programmed to play it safe and charge as a 6V battery. Let it charge for a little while then stop the charge, unplug the charger or disconnect a clamp for 10 second then reconnect, and try charging again. It might require a few cycles, but it will recover eventually.
I worry if you spend a bunch on a ebike..when the battery starts losing range , will the batteries be the same and will you even be able to get the same size/shape battery when you need one ?
Yes battery chargers are at times use full . But 6volt system the good old crank handle is all I use . Yes the tractor has a 10 watt solar panel it is the charge system the generator stopped working in the late 1960s it all so has a crank handle
I have a 6 - 12 volt charger that is at least 50 years old - it still works. Check yard sales, it should cost less than 10 $'s.
Hey Scotty ..have you got an opinion on the "OPTIMA" chargers ... they claim lot of functions in relation to charge and maintenance of both lead/acid and AGM's
Would be nice if the battery charger showed an accurate (to the nearest tenth of a volt?) voltage as across the battery and the amp flow rate in real time
AGM "Odyssey" battery needs special charging or cycle?
UA-cam suggested similar categories which are adept, "sketch comedy"😂
Scotty should swap his Ninja intro to an E-Bike intro :)
Aaahhh, FJR1300. Great choice that I am in the market for right now.
You can get a velcro strap for your electric bike to keep it from unfolding.
So since you have to have a special lithium battery charger for lithium batteries, then what happens when it dies and you need a jump? You can't jump it with a regular battery?
You can jumpstart a car with a lithium battery in it with no problem at all. It shouldn’t damage anything because you’re only connecting it for a brief period.
My instrument cluster keeps going on and off then it will eventually stay on should I replace the cluster or have wiring checked
Beware of folding bikes. Folding the bike can pinch the cables running through the frame. This can ruin the controller.
so, if they last forever, probably one can get one of those used at a garage sale! I once bought 2 gigantic HEPA filtering systems for $6. they were worth hundreds.
I totally agree that most, maybe all, switching mode non iron transformer battery chargers are crap. I’ve tried several of the light weight switcher type over the last 30 years and none of them performed 100%. One of the better light weight electronic chargers is is the EverStart maxx 40A - it will charge a not completely dead battey and give a 40 amp or better boost to start a car with worn down battery.
My go-to is a Century Model 141-272-000 transformer based charger with 100 amp boost which I bought back in 1994. It never fails unless a battery is truly hopeless. If there is any chance, the Century will get the battery going.
The DSR charger looks like the modern equivalent and if Scotty says it is good, it probably is.
I just looked and the Century charger I have may still be made and is now Model K3151-1. It is about 200 bucks. Back when I bought mine, it was about 65 bucks according to the receipt in the box. Inflation!
If lithium batteries need special chargers how does the alternator charge it?
Hey Scotty do after market warrants work and if so witch one is the best
Weighing electronic devices. Yup, a heavy device must be better because quality Integrated circuit's performance depends on the weight😊
Thanks I have added the red one cheap charger for 54$ in my ebay cart but now watched your video so I will not buy that red one, thanks to save my money.
So, how does the standard alternator play with a lithium battery?
How about jump starting with a standard battery?
The reason the specific charger is that lithium charging curves are different from lead-acid. Lead-acid voltage starts low and increases as it comes up to capacity. Lithium will go to 12.8V immediately and just stay there. So, a lead-acid battery charger will think the lithium battery is bad and stop charging. Either a charger with a special lithium charge function or a separate lithium battery charger are required. The alternator is fine, since it is just a voltage source and not really a charger. When the engine is running, it just outputs a voltage to whatever battery you have attached and won't stop until you turn off the engine.
@@roundedrooster Thank you for that explanation! I suppose the same explanation applies generally to jump starting?
@@Mikey-ii8ef The Jump Start should still work. The battery is designed to input or output high current. A charger with an Engine Start feature isn't following a charge algorithm, it just dumps out as much current as it can for a limited time. The lithium management circuit on LiFePO4 batteries are supposed to be designed to handle this.
Do you have to use a modified alternator if you use a lithium battery?
What do you think about Hondas new electric bike. It looks like a cassette tape on wheels 😂😂😂. I want one
if the engine was locked up when you used the cheap battery charger and the more costly battery charger, then how can you say the cheap one did not work? did you check the battery with a voltmeter? sounds like the battery was good, but the was no good.
I had a Schumacher cabinet charger that is 2A to 50A charge and 150A boost... worked well for years then this last year it went stupid and blew the TIPM in my Ram. So even the "good ones" go bad
