I had a 60Ah car battery that has been sitting for 6 month , measured 4.9 volt, I charged it with variable power supply at home but started low , gave it 6volt at the begining and stepped up a little ~once an hour as the battery charged , finally the battery fully recovered, it's been a year now she still running my car, my point is that the reality taught us that even lower than 6 volt batteries can still be recovered
yey, thanks for the video, it was the same here 0-10c temp, charges up a not so good battery after 24hrs on pulse its a maintenance free battery which has a small round window telling you if its flat (black) needs charging (silver) and (green) well its never been green since i bought it 6yrs ago, but its now green brilliant and over 13v dropping down to 12.9 like yours, cheers from cold UK.
This device is a must have for every one that has a weak or dead battery on their vehicle. I hope it will repair my weak lead acid battery for my motorcycle. I am so excited!
I have this exact charger. Like you, I bought it with not a huge amount of faith that it would recover the battery which I thought was a lost cause , but it absolutely works.
Folks the repair mode is worth well doing :) from time to time but by leaving your battery on say trickle charge that will keep your battery in good condition as a rule .
i think you need to charge it normally first until it reads full.. even if it cant hold charge.. then after its fully charged you pulse for 36 hours.. at least thats what ive learned and works well ! great machine yea!
Thank you, sir. As a ham, CB & UHF radio operator we always keep backup batteries & inverters in case of emergency. Well now, this possible emergency is a whole lot closer with this Russin business. I have this same charger. They work. I recently was given an 85 Ah battery. I topped up this 85Ah sealed leisure battery (I distill my own water) by drilling 6 holes topping it up & resealing it with hot glue so easy to remove & re-top up in the future. I had it on pulse repair overnight & it brought it back. My only test was on a 12-volt kettle that draws about 14 amps & It boiled a full kettle twice so far & close to an hour of 14 amp constant current draw & it's still well over 12 volts, but I will give it some more pulse charging. I have 2 126Ah truck batteries that I have been maintaining on pulse repair in case this Russian war business goes nova & the UK loses its power grid with conventional or EMP weapons. UK power grid is very fragile. God help us if that happened all nuclear facilities could not be maintained & would explode. If there is a god that is.
Dale, I have a 1991 Jeep wrangle renegade, 4.0 eng. 5 spd. A/C. I need to replace my battery. The battery that’s in it now is a group 58, O’Reilly’s Extreme Super Start 58EXTJ. It had 760 CC, 84-month P/R warranty with 3-year free replacement. All the new ones I see (group 58) only have 2-year free replacement and very low CC. and are expensive. I noticed a guy on RUclips with a YJ put in a group 65 and it looks to fit perfectly and is more powerful, better warranty and less expensive. What’s your thoughts. Thanks for your and daughter’s great videos.
Hey man. You just let me make sure the portable jumper is useless. And You can just save your old battery. I have always gone abroad long time and nobody cares about my car. Its amazing
hi my battery is totally drain and not used for a long time, it has no spark when i combine positive and negative. Can I revive the battery using that charger??
I bought this exact same model online (same box and everything) for the equivalent of $8 (I live in Thailand) I'm hoping that it will resurrect a few 12V batteries I have installed in uninterruptible power supplies (UPS). Your video gives me hope! Thanks for the detailed video - I'll leave mine repairing overnight. I really should get a volt meter.
@@thaninsainamthip8597 The device charges batteries well, however the repair mode does not do much - any time I try it, the charger says "repaired" but it doesn't work. It might be because of the type of battery in my UPS 🤷♂️
@@lanta-darren if they are not lead-acid then maybe that is the reason, I got a similar charger and the booklet says: "do not user with batteries other than lead-acid"
Thanks for the video. I have this charger too. Just want to let you all know that you dont really need a multi-meter when you have this charger. When the charger is connected to the battery, without the mains plugged in, the readout shows the battery volts. If you measure the volts, when the mains are connected, the readout shows the charging volts which are always higher than the battery volts. Its good practice to connect the battery first before plugging into mains and disconnect the mains first before disconnecting the battery. I also read somewhere that pulse repair can take anywhere between 4 to 48 hours but this device is meant to switch back to normal charge after 24 hrs of pulse-repair mode according to the instructions. Today I'm trying to resurrect my battery with pulse repair because its only getting to 10.7V with a normal charge and cranking the engine can be a little slow. I'll leave it for the full 24hrs on pulse and see how it goes. It will be interesting to see how it runs for in repair-pulse mode. My car has heaps of electronics modules so I removed the battery from the car to pulse it and used my 12V mower battery to keep the car electronics on a temporary 12V supply. Update - Have tried repair on two batteries even tried leaving it in repair mode for several days. Still 10.7v. It didn't work on either of them. I think that the pulse repair mode might be a bit hit and miss (or possibly a scam). If a cell in a battery is too far gone its time to get a new battery. Im guessing one cell is gone because the voltage would only get to 10v.
you need to charge and then turn to repair and then charge and repair. Do it for several cycles. The charge put a high voltage and repair low voltage into the battery,
10 V mean one cell out from 6. The cell short circuit bro.. just replace new If your battery maintain and hold 12 V range but your SOH % low then you need to pulse repair.. up to SOH 100%. SOH checkes with battery analayser Multimeter will not tell your battery health
I've got a different brand charger (NEXPEAK) but it has the same functions like yours. I've had my battery on repair mode for 8+ hours with the screen flashing up & down 60% - 100%. Using a voltmeter I can see the voltage oscillating between ~12.5v ~ 13.5v. Disconnecting the charger I checked the battery voltage & it read (at best) 11.6v...still very low! How do I know when this battery is 100% repaired? What does the screen shot show?
That high, ~14+ charging rate looks good, you should monitor the heat and let it go longer. Many fancy chargers will charge at 16V for a repair. Another RUclipsr uses a DC welder to hit it with 16V.
You need to leave the repair mode on for at least 24 hours to do the job depending on the AMP HOURS eg our batteries are no less than 100 Amp Hours and please don't mistake the cranking amp hours marked on the battery as we use a certain brand and model of charger and they are fitted into our ambulances and after the repair mode is complete it does switch to charge mode and yes maybe only a few amps charging. Sound advice it depends on your battery amp hours not the cranking amps. A tip which you may find is helpful switch the repair mode on say every 3/6 months and yes it will take less time to repair :) All our ambulances when not in service are always plugged back again to the mains electricity to keep the batteries charged up and most ambulances may have 2 or /3 or 4 batteries fitted but we always fit the Smart Charger unit to the starting Battery :) Most ambulances will have a 12 volt power Shunter fitted , the shunter will charge up the battery which appears to be lowest and then the shunter will shunt between all the batteries so by fitting those type of chargers we have extended the life of the batteries by at least one year :) so the information I have typed and my advice is useful kind regards, Ambulance Service Northern Ireland. UK Please note we do not endorse any type of Intelligent Smart Car Battery Charger Pulse Repair unit.
@@pashiki5480 not recommended as we leave the charger on until complete so once you start the charger my advice is to let it run it's course . How ever our ambulance batteries would be around 100 amp hours + so a car battery would be much less amp hours wise.
It may take several days for it to complete again like others mentioned, the larger the battery capacity the longer repair time. This is also true for the more damage a battery has the more time it will take to prepare. 36 hours is the minimum amount of time for a complete repair, and it could take up to a week. When you do the repair mode, when it is complete it will say "END".
Pulse/desulfator charges can be hit or miss on recovering batteries. They are worth a shot though, I had an interstate car battery last 12 years from using a desulfator periodically.
Nice. I am trying to get there with my pickup. Its a cool but plain 90's GMC that does everything I need and 7 years+ on the battery that I got with it. It got 8 hours on repair cycle after sitting for about 3 months and dropping into the 10v range.
Hello, i have a question. i put the battery on the charger and i measured the voltage. Its 15v , is the voltage to high? is the charger it broken? Thanks
I just tried my charger with my audi battery that was sitting for Two years. It took 3-4 days to complete the cycle. I haven’t tested the battery yet tho. I also used it on my mothers two batteries in her mobility scooter and it took over a week and I had to put another charger on it just for it to start doing the pulse cycle.
Hi, I bought one of the same, the problem is, the cooling fan is not working when the power is switch on and the battery drains very fast after charging. Any advise?
You have probably sludge on bottom of battery which make electrical connection to cells, you can try to remove complete battery fluid, flush cells with hot distilled water few times, add new fluid (Sulfuric acid 35%), and than run repair mode. But it pretty much of job, and you are working with acid so it can be dangerous. There are some YT videos about it.
If you direct charge battery, then direct connect the charger clip to both terminal. But if the battery is directly attached with car (which mean you didn't disconnect cable from battery), then connect + to battery terminal + and - to car chasis. This is to prevent your car from voltage damage
Work well on my batteries. Depend on CCA and SOH. Larger CCA tooks longer to repair.. Lower SOH tooks longer time to repair.. My 380 CCA tooks about 4 hrs to brought from 90% to 100 % SOH. My 720 CCA batrery tooks 32 hrs to bring 86% to 100 %SOH. In principle need to charge full and wait for 1-2 hrs. If it still have 12. 6 volts mean you still can desulphate. If say 10v or lower means one cell already defect due to shortage or etc. if it could not maintain charge on 12.6 with high SOH means you by mistake overfill the electrolyte level. Have one battery that i charge from SOH 47% to 100% with 300CCA. It tooks about 11 days...
A 12 volt battery charged at rest with a 12.7 v reading is in good shape. Allow to stand for a while to let surface charge dispel. An altimeter or battery charger will charge upto 14.4 volts to go past the normal standing voltage of the battery and is not a reading you should see on a resting charged up 12 volt battery. Hope this helps
1 - When the battery is deeply discharged. It will be desulfated. You should use repair mode for some time (to precharge battery), then normal mode and repair again. 2 - Always when you want really fully charged battery with correct electrolite density @ 1,28g/cm3. First you should use normal charging, when charger says "FULL" choose repair mode for 24 hour. During charging the battery should be disconnected from the car.
I suggest on all batteries of 2+ years old, at least once per year make at least 1 cycling (Discharge to 10,8V , then charge in repair mode), check fluid level before process, add distilled water if needed. This should maintain low level of sulfide oxide on battery plates. For battery discharge check DC loads, there are cheap ones on Ebay/Aliexpress ....
harbor freight voltmeter OUCH!! I saw one of these falsely read no voltage because the battery was a little weak. That person thought they turned off the correct circuit breaker and got hit with an arc flash as a result. The meter had a good display (wasnt weak) and had no low battery indicator. THIS IS UNSAFE!! i suppose you could buy a second voltmeter to test the batteries on your first one, but you better hope the second one is not low too.
I don't know this car, bur cranking sound suggests battery barely starts the engine. I think it would have to be in repair mode for a long time, maybe even a few weeks. The author mentioned the battery was in repair mode for a couple days, so this is probably the minimum work required. Although 6V total at the beginning was a way to low, so any result is a good result!
@@pavel9652 It can depend on the AMP HOURS of your Battery please note try not to stop the repair if you can as the longer you leave it on the repair mode the better :)
Been charging mine for only 9 hours on Repair mode and it's working great for my 40Amp battery. Before charging it was at 0.6V ! Can you believe that??
Sonyviva308 that's about right those hours :) but as you say your battery is only 40amp hours and in passing you can't damage the battery if you leave it on longer as it just stops repair and goes onto trickle charge:)
@@donkirk5433 Yeah Its safe! And oh update : Turns out after 9 hours it wasn't finished. It was showing at the last blinking bar and Just wait till it says FUL. That was another 6 hours of waiting
I guess the multimeter showing even if at 12.7v (from my experience) doesn't meant the battery is good. You need real battery health tester to check the real battery charge such as the cold crank amps
Shafey It chargers a flat battery. When you leave your car for a long time without driving it, or especially during cold weathers your car may not start, so this would charge it back up so it starts again
You have to look at the car battery's amp hours rating. Some car batteries are rated at 100 amps. That means you would want to buy a 10 amp charger. A car battery rated at 50 amps would only need a 5 amp charger. It's going to take a long time to charge a car battery rated at more than 70 amps with a 5 amp charger. Most car batteries are rated at 50 to 70 amps. You don't really need a 10 amp charger to charge them.
The battery in my car didn't actually have the battery's AH rating on it. I had to look at the battery's model number and search for that battery on the internet. I think the battery has a 60 AH rating. The biggest problem with the battery in my car is that it doesn't really have enough cranking amps to start the engine. It's the dealership's original battery. I think it only has 450 cranking amps. A good car battery usually has at least 500 cranking amps.
Suggesting to check fluid level inside battery before repair process , if missing add distilled water. Even if no fluid is missing, it is good practice to add some small amount (i.e. 10-20 ml) since pulsing and overcharge process will evaporate some of the water. Check fluid level after repair mode also.
Unfortunately, the charger has no noise filter at the input of the switching power supply. It thus produces a really large amount of interference in the distribution network. This may limit the functionality of other devices, especially electronic devices, near the charger. This was the reason I came to this fundamental shortcoming of the charger. The charger definitely does not meet the requirements of Electromagnetic Compatibility standards! Personally, I solved this by inserting an interference filter from a non-functional ATX PC power supply. In my case, this solution reduced the interference to an acceptable level. Otherwise, the charger itself works well.
Martin strange but we have had no problems or interference to any of our medical equipment on board our ambulances and that includes our radio system and our mobile systems.
imma not a pro, but need a video that cranking the engine and see the voltage while we cranking. you guys know what i mean right? imagine old battery while cranking volt gonna go down like 9.5v never can start the cold engine even without cranking voltage stated 12.6v something . and after pulse we need to see if volt can hold up while cranking the engine because , i got 1 smart charger without repair mode, 12v 20a charger easy to get my battery alive again , but only can get below 5 time cranking
These things cause horrendous interference on various radio bands, remote car locks, HAM radio, AM and FM broadcast reception, 5G, radio astronomy, aircraft communications, and weather radar. They're Chinese junk and don't meet the EMI standards. It's basically a wide band jammer.
If your battery has caps on the top of the battery check this page out A trick to rejuvenate a car battery - RUclips as we do that from time to time but most batteries now days some sealed :(
Charge till you got 12.0 v. Leave for 2-3 hrs.. Ensure battery still hold 12 V.. if you get 10 V you just got one cell defect out of 6.. or one cell just short circuit...buy new battery. If battery hold charge of 12 v then check CCA with battery analyser.... if SOH say 76% pulse repair till get 100% SOH... then charge till full SOC 100%.. trickle 1-2 hrs- you are done.
I just replaced a battery on a car that hit 5 years old last summer still holding 12.5v but dropped to 11.1v when it got down to freezing. After leveling the water up and doing overnight 'repair mode' no change. I could see some damage to a cell when checking the level and sure enough no help. The truck I drove to buy the new battery is only started two or three times a month and has a 7 year old battery that I did repair mode overnight on a couple months ago and it holds 12.6v and starts fine even in cold weather. My success rate so far is 50% and I am happy with the $25 I spent on the charger
If living in the city, yeah easy to just buy new battery. But if its hard to buy new one, charging is an option you have. It's good to have one as standby.
Thanks! I had no idea how long to leave mine on "pulse repair" mode for a thorough job. Appreciate ya sharing your findings.

But it pretty much of job, and you are working with acid so it can be dangerous. There are some YT videos about it.
manual quite confusing.
it said plug + to + and - to -.
but on the back paper said + to + and - to chasis if the battery intact with car.
If you direct charge battery, then direct connect the charger clip to both terminal. But if the battery is directly attached with car (which mean you didn't disconnect cable from battery), then connect + to battery terminal + and - to car chasis. This is to prevent your car from voltage damage
Can i do recondition mode while the battery is hooked up with the car?
Yea
Work well on my batteries. Depend on CCA and SOH. Larger CCA tooks longer to repair.. Lower SOH tooks longer time to repair.. My 380 CCA tooks about 4 hrs to brought from 90% to 100 % SOH. My 720 CCA batrery tooks 32 hrs to bring 86% to 100 %SOH.
In principle need to charge full and wait for 1-2 hrs. If it still have 12. 6 volts mean you still can desulphate. If say 10v or lower means one cell already defect due to shortage or etc. if it could not maintain charge on 12.6 with high SOH means you by mistake overfill the electrolyte level.
Have one battery that i charge from SOH 47% to 100% with 300CCA. It tooks about 11 days...
And that's because it's a battery maintainer and not a battery charger. Much lower current output (amps) than a battery charger.
I would like to know if this works like a battery desulfator when in repair mode?
I think it is. I have one and if you listen carefully in the repair mode the battery sounds like something disolving inside.
Diane yes your correct :)
@@arkangelMX2009 Yes correct again :) We have been using them for a few years now but they have come down in price and much smaller in size.
can i charge my car battery even if it has 12.7 in it? .... its just for additional volts in it. thanks
A 12 volt battery charged at rest with a 12.7 v reading is in good shape. Allow to stand for a while to let surface charge dispel.
An altimeter or battery charger will charge upto 14.4 volts to go past the normal standing voltage of the battery and is not a reading you should see on a resting charged up 12 volt battery.
Hope this helps
Is this suitable for AGM batteries?
Daniel but us the setting for AGM
would it be safe to say any battery charger with a pulse repair mode can achieve the same result please
I think so, as long as they have the feature
Good video! When is it recommended to use repair mode?
If it's reading under 14.5 volts after full charge i believe
1 - When the battery is deeply discharged. It will be desulfated. You should use repair mode for some time (to precharge battery), then normal mode and repair again.
2 - Always when you want really fully charged battery with correct electrolite density @ 1,28g/cm3. First you should use normal charging, when charger says "FULL" choose repair mode for 24 hour.
During charging the battery should be disconnected from the car.
I suggest on all batteries of 2+ years old, at least once per year make at least 1 cycling (Discharge to 10,8V , then charge in repair mode), check fluid level before process, add distilled water if needed. This should maintain low level of sulfide oxide on battery plates.
For battery discharge check DC loads, there are cheap ones on Ebay/Aliexpress ....
harbor freight voltmeter OUCH!! I saw one of these falsely read no voltage because the battery was a little weak. That person thought they turned off the correct circuit breaker and got hit with an arc flash as a result. The meter had a good display (wasnt weak) and had no low battery indicator. THIS IS UNSAFE!! i suppose you could buy a second voltmeter to test the batteries on your first one, but you better hope the second one is not low too.
How long or times you crank the engine? Does the battery still work or it just dead?
Battery still works great! No issues now.
I don't know this car, bur cranking sound suggests battery barely starts the engine. I think it would have to be in repair mode for a long time, maybe even a few weeks. The author mentioned the battery was in repair mode for a couple days, so this is probably the minimum work required. Although 6V total at the beginning was a way to low, so any result is a good result!
@@pavel9652 It can depend on the AMP HOURS of your Battery please note try not to stop the repair if you can as the longer you leave it on the repair mode the better :)
After battery is repaired, what is life span? I think should be less than 5 years.
Albert we get a round 4 years out the ambulance batteries but then we have a lot of demand as in medical equipment fitted into ambulances.
the good old russian pulse charger for syberian battery maintenance.
Been charging mine for only 9 hours on Repair mode and it's working great for my 40Amp battery. Before charging it was at 0.6V ! Can you believe that??
Sonyviva308 that's about right those hours :) but as you say your battery is only 40amp hours and in passing you can't damage the battery if you leave it on longer as it just stops repair and goes onto trickle charge:)
@@donkirk5433 Yeah Its safe! And oh update : Turns out after 9 hours it wasn't finished. It was showing at the last blinking bar and Just wait till it says FUL. That was another 6 hours of waiting
I guess the multimeter showing even if at 12.7v (from my experience) doesn't meant the battery is good. You need real battery health tester to check the real battery charge such as the cold crank amps
If I'm driving and my battery died can this save me? I mean will this jump-start the battery without electricity?
Nope, u need a jumper not a charger
@@gusdhesewana9607 so what does this charger exactly do to my battery?
Shafey It chargers a flat battery. When you leave your car for a long time without driving it, or especially during cold weathers your car may not start, so this would charge it back up so it starts again
@@karolpawlowski3785 Thanks so much man
You can buy a jump starter pack which is a small power pack with jump leads that can jump your car if it died.
How long did It take to repair the battery?
Watch the video ....
@@D3M0ify ok
Which charger is best?
1) 3 Stage or 7 Stage charger ?
2) 5A or 10A ?
You have to look at the car battery's amp hours rating. Some car batteries are rated at 100 amps. That means you would want to buy a 10 amp charger. A car battery rated at 50 amps would only need a 5 amp charger. It's going to take a long time to charge a car battery rated at more than 70 amps with a 5 amp charger. Most car batteries are rated at 50 to 70 amps. You don't really need a 10 amp charger to charge them.
The battery in my car didn't actually have the battery's AH rating on it. I had to look at the battery's model number and search for that battery on the internet. I think the battery has a 60 AH rating. The biggest problem with the battery in my car is that it doesn't really have enough cranking amps to start the engine. It's the dealership's original battery. I think it only has 450 cranking amps. A good car battery usually has at least 500 cranking amps.
The battery charger pulse feature is very interesting.
Yes! It's a good feature
I just bought it in amazon i cant wait to used it!
@james: did this charger work?
Hello, does the battery still work?
Sure does!
@@JeepSolid can I use this charger without removing the battery from the car ?
@@flamurhamati2976 Yes of course as ours's are built into the ambulances.

Many thanks
Dear Timothy Wenner. I appreciate that you like to be first, however, you cannot eclipse the master. ;-)

Suggesting to check fluid level inside battery before repair process , if missing add distilled water.
Even if no fluid is missing, it is good practice to add some small amount (i.e. 10-20 ml) since pulsing and overcharge process will evaporate some of the water.
Check fluid level after repair mode also.
Most are sealed now
Unfortunately, the charger has no noise filter at the input of the switching power supply. It thus produces a really large amount of interference in the distribution network. This may limit the functionality of other devices, especially electronic devices, near the charger. This was the reason I came to this fundamental shortcoming of the charger. The charger definitely does not meet the requirements of Electromagnetic Compatibility standards! Personally, I solved this by inserting an interference filter from a non-functional ATX PC power supply. In my case, this solution reduced the interference to an acceptable level. Otherwise, the charger itself works well.
Martin strange but we have had no problems or interference to any of our medical equipment on board our ambulances and that includes our radio system and our mobile systems.
Just discovered the noise issue it's pretty bad, definitely needs a filter it's affecting the entire house.
imma not a pro, but need a video that cranking the engine and see the voltage while we cranking. you guys know what i mean right? imagine old battery while cranking volt gonna go down like 9.5v never can start the cold engine even without cranking voltage stated 12.6v something . and after pulse we need to see if volt can hold up while cranking the engine
because , i got 1 smart charger without repair mode, 12v 20a charger easy to get my battery alive again , but only can get below 5 time cranking
is the charger still working 3 years later?
Yep. Still use it on projects
excellent ty@@JeepSolid
@@JeepSolid hello, Will it lessen the long hours completion in pulse repair mode when you do pulse repair again in the next day ?
I was told you are suppose to leave the battery for 72hrs after charging before retesting else it will give a false reading
Also with this charger the repair mode will turn off when it's done automatically
Chris depends on the AMP HOURS of your battery but a normal car battery say around 65/80amp 24 hours should do the job.

you have a problem with the starter
Use this. Extended battery almost to 5 year. 😂
Why it has russian labels?
Food ,I have one. Remember you took it off while in circle. Would’ve taken 14 hours.

You need to run a conductance (capacity) test. State of health and state of charge.
Which device does that?
Nevermind, found it on aliexpress and temu. Keyword: Car battery analyzer
Not all calculate the same. Ther are many that are inaccurate. Bst200 ancel calculates conductance well.
bst200 seems nice tester, but almost half the price of a new car battery. After all not sure if I need it :)
Is this ok for Toyota Prius ?
Yes, anything
sounds like you got more problems than a battery. next on your list should be a starter motor
These things cause horrendous interference on various radio bands, remote car locks, HAM radio, AM and FM broadcast reception, 5G, radio astronomy, aircraft communications, and weather radar. They're Chinese junk and don't meet the EMI standards. It's basically a wide band jammer.
@Saiyan Prince yep
I bought the same charger for 9 USD in india
If your battery has caps on the top of the battery check this page out A trick to rejuvenate a car battery - RUclips as we do that from time to time but most batteries now days some sealed :(
Charge till you got 12.0 v. Leave for 2-3 hrs.. Ensure battery still hold 12 V.. if you get 10 V you just got one cell defect out of 6.. or one cell just short circuit...buy new battery.
If battery hold charge of 12 v then check CCA with battery analyser.... if SOH say 76% pulse repair till get 100% SOH... then charge till full SOC 100%.. trickle 1-2 hrs- you are done.
Is it okay to pulse repair a battery everyday until i get the higher SOH CCA ? Will it ruin damage the battery by using pulse repair everyday?
So you charged a low battery. Big deal. Why is no one trying these repair chargers on batteries with a bad cell or 2?
Thanks for watching
I just replaced a battery on a car that hit 5 years old last summer still holding 12.5v but dropped to 11.1v when it got down to freezing. After leveling the water up and doing overnight 'repair mode' no change. I could see some damage to a cell when checking the level and sure enough no help.
The truck I drove to buy the new battery is only started two or three times a month and has a 7 year old battery that I did repair mode overnight on a couple months ago and it holds 12.6v and starts fine even in cold weather. My success rate so far is 50% and I am happy with the $25 I spent on the charger
pulse repair need 8 hours for car
It depends on the battery size but generally you should leave it on for at least 24 hours
