Using a cheap battery charger to restore a dead car battery

- I use the Foxsur charger to restore a dead car battery. This is one cheap battery charger that works! The Pulse repair function is particularly useful for reviving dead batteries or those that have been sitting unused for a long time. This tool can be used to show how to desulfate a battery especially for the DIY enthusiast who just needs a simple tool and does not have all the experience to go into more complicated battery restoration procedures. Look at it as DIY battery desulfation.
NB: If battery plates are damaged or the battery has leaked electrolyte this tool will not work.

I have the Exact same charger and I use it for a couple of vespers I’ve got to keep them topped up as well as my cars they are cheap and inexpensive but absolute brilliant charges I think I paid £12 from eBay brilliant highly recommend thank you for doing this explanation 👌🏼
Really good, cheap piece of kit!!!
Can we jump start our car with it?
Nope. Just a charger.
@@DIYAutoworksNG hello, would I 🔌 directly to the wall socket or use an extensions? I am a woman n I wanna make I have this, jumper cable, tyre pumper in my car because I have experience flat battery a few times I expectedly. I know I have to read the Manuel but I just wanna know because u didn’t show were u plugged the charger too.
Can be plugged to the wall or an extension depending on far the battery is from the device.
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!

@@DIYAutoworksNG It's a spammer, I have seen the same post by different user accounts.
Thanks for flagging.
Good to know I'm not the only person that has had a lot of success with the Foxsur charger!
Your video is the first one i watched while sitting in my car due to dead battery. Your explaination is very helpful and convincing. Subscribed!
Many thanks, mate! Super stoked to have you on board!
Job well done! People spend a ton of money on batteries not knowing about alternative ways to revive them. I just bought a Black and Decker battery charger, voltage checker, conditioner, and alternator checker all in one. It takes forever for the battery conditioner, but it's a smart thing to do as batteries do start to become sulfated overtime under lower voltages. Great vid, thanks for sharing!
Thanks! Great buy with the all in one!
Good little charger, had mine 3 years,its never missed a beat and revived a few batteries with solid results.
Yep. Thanks. Great to have a solid review from someone else! Incidentally, I used mine yesterday on my neighbour's dead battery.
One question: I have been using this charger, since January of this year, in a 3 y.o. Lead Batery of 700 AMP car battery, because it was waking up in 11.9 volt and didn't star the car. The fist time revived with the repair mode for 4 hours. Since then I was doing a repair charge of 4-6 hours once a month. The other mode doesn't activate: shows FUL even if the charge is low, so I can't only do the repair mode. But in the last two months the battery loses its charge overnight. I repair for 30 minutes and I can start the car, drive, and keeps good for about 6 hours. Any thoughts? How can I improve this? A repair charge of 24 hrs? The longest I have used that mode is 8 hours and still loses the charge overnight.
Thank you, sir. I have this same charger they will recover most batteries. Lead acid & gellies I have used it on. As a ham, CB & UHF radio operator we always keep backup batteries & inverters in case of emergency. I have a few 3.3, 7 & 12 amp gel cells & some larger lead-acid ones up to 126 amps. These are for an emergency & a possible war is a whole lot closer with this Russin business now going on. These chargers work well at improving battery performance by dissolving the crud on the plates. 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
Some nice DIY with the drilled fill up holes! Tackles the water loss through the valves for those VRLA batteries. Happy to hear it hasn't popped under pressure too! Do stay safe and wish you the best. Hoping for the best in the current conflict! Stay safe.
Thank you so much for the explanation in the beginning. My battery went dead after i forgot to turn the key all the way while talking on the phone!! I did not understand why i couldnt start my car even if i got help to start it afterwards and went through the highway to charge it. Your video really helped me, much thanks !!!
Very happy you found useful. Thanks.
Thank you for doing this review. I was debating whether to get this item or not, but I have just ordered one after your experience.
Great choice for the price. Mine still works great.
It is my understanding that in order to use this battery charger to repair a battery, it is necessary to press the "Repair" button. It seems that button was not pressed in the video. Also, when the Repair button is pressed, the charger will display PUL. PUL means that the charger is pulsing to repair the battery.
Correct observations. I only charged the battery
just order one now, Thanks!
Great! Hope you enjoy it!
Hey there - I have a different brand of charger, but from what I can tell, functionally identical. My car battery's gone (internal lights were on...). I connect the + first, connect the -, but as soon as I plug the charger in power, I get an "ERR" on the charger screen. Any clue what it might be? Thanks in advance!
I recommend you check the documentation that came with the charger. Mine doesn't display that sign, but it could be a cellin the battery is gone, or even a fault in the charging system like a faulty starter...
Bought a new battery, $200......Recharged my old battery and took the new one back! The battery charger cost me $20!
Nice!
@@DIYAutoworksNG The mechanic at "Honest1 Auto" Wanted $168 to check the battery! Thank god for UA-cam and people like you.
Lol. Just on battery testing, I also got this for less than $30 I think. Super useful for testing the battery, alternator and starter.

@@DIYAutoworksNG I have a 2015 Fusion Hybrid, that sits a lot. When ever I use it I had to jump it with a battery pack
This drained the battery. I got the red light telling me to safely pull over, even thought the car drove fine. Found out later the 12v battery was low, due to lack of use. I use the car maybe once a month. Now I leave the trickle charge on it and all is well
👌🏼
Thanks for the information ♥ ️ I have a problem with this charger and I lack experience. Can you help? ♥ ️ ♥ I put maintenance and the operation was successful, but the problem The battery is empty of charge 0/100 and despite long hours in this charger does not exceed 20/100 what is the solution⛔⛔
It's not working for me when I plugged the foxsur charger in it says Full but the battery is fully dead I even put it on the repair mode for 18 hours and the battery was still the same fully dead.
If you use a multimeter, what voltage does the battery read?
I have the same charger, I put it to the test on six bad batteries, it did absolutely nothing for them , all six were not improved at all in any way, my wallet was lighter than it was before I bought this charger, the only thing it did accomplish
Do you also have this specific charger? I see you commented on the other kind of charger. As I mentioned before, I have also had some batteries that this did not work for just as the tool doesn't claim to revive all dead batteries e.g. batteries with: damaged cells, depleted fluid level, or a voltage below 8.5volts.
On the other hand, it has been for getting restoring weak batteries which do not have the above limitations
Hi brother,
I just want to know,how to use repair mode? Need to press any button or it run automatically? Looks like have button at repair word on the charger.
I want to buy this charger from online website and i don't want buy something i don't know how to use.
Hey Omar,
Thanks for reading. Once you hook up the device it starts charging. This will be for batteries that are a bit low on charge. For batteries that have sat totally discharged for a prolonged period of time, repair mode is indicated. To activate repair mode, simply press the repair button.
@@DIYAutoworksNG thank you for this review and clarification of repair mode. I have bought the same charger and was not sure when I was supposed to use the pulse 'repair' mode. So I should 1st charge battery normally to see how high voltage goes and if it does not reach 12.6v after many hours then I should use repair mode?
Thanks for the compliment.
If it's a car battery, just charge normally. Note that it may take many hours to charge if the battery is low. If the battery has been dead for a very long time, you may use repair mode from the scratch. Also, if you have a 4AH - 15AH battery, you should only charge it using repair mode.
Can i use repair mode while battery is hooked up with the car without taking out the terminals?
@@markarvinflores229 for car and battery safety, i think better you take out your battery and charge it on the floor. Or just disconnect battery terminal with car.
Why did you not use “repair mode”?
My main aim was just to charge the battery, as it was really new and didn't need the repair function. The car had a parasitic drain and kept draining it. I latter found the source of the parasitic drain.
If I were dealing with an old battery that isn't holding a charge or a small capacity battery (4-15AH), the repair function will be first choice. That said, using repair mode even for a new battery will still charge it and cause no harm. It would rather desulphate the battery (if present). So I do like your suggestion.
Piyke DIYAutoWorksNG thank you for the answer 🙏
@@DIYAutoworksNG That's wrong answer. Always perform repair mode for 24h when your battery is flat - to build density of electrolit
The manual of the device does not say to use the repair function every single time. This was a new battery that lost its charge through a drain. Didn't really need the repair function.
Hello
12v 60ah 510A battery I need recharge
Which mode is better?
Normal mode or pulse repair mode?
Which is correct
Depends. If the battery has been growing weaker and weaker over time, a repair will be better. If if was a rapid discharge event e.g. Left headlights on, regular charging should be fine.
I have a motorcycle wet battery, it is few months old, discharged due to not riding the bike for months, switch on bike, lights not even light up, so i took the battery out, distilled water level is still max,
Then use this charger, it says battery has 11.2v, so i turn on the charger, it shows FUL on normal mode no matter what, then I start Pulse repair mode and leave it overnight, hopefully it saves the battery.
Yea. It will usually show Full for small capacity batteries. That's the reason why the manual recommends using only the repair mode for small batteries. Do let me know how it goes.
@@DIYAutoworksNG first few hours it looks nothing happened, battery wasnt getting warmer at all, i still let it be anyway, and 12hours later, it's still on pulsing mode but the battery is now warmer and some little bubbles in it, it's working! It is now 13.9v, battery is going strong :D, glad i bought this charger, useful when you have vehicles but not driving them often like before due to covid
Absolutely!!! This charger is worth every penny, mine has paid for its purchase. I have used it for car as well as power generator batteries! I remember how confident my power generator repair guy was when he said my current battery was gone. It's been close to a year since and the battery is still going strong.
One tip. I have never seen this charger go from pulse mode to FULL. I just use the estimated duration in the manual: 8hrs for small battery and 24hrs max for any other size. Very happy for you!
@@DIYAutoworksNG nice! I bought it at RM40 about USD 10, worth it
Can I use this battery charger and leave it on my motorcycle battery as a float charger for the winter when I don't use the motorcycle
I have just bought one of these and reached "FUL" same brand Bosh but "S4 021" due to leaving my car lights on for 3 days. Quick question why does it recommend leaving it on for 1-2 hours after FUL? Is there any specific reason? Will it enable my car battery to hold a better charge?
I feel like my Bosh S4 doesn't hold a good charge even though it is brand new and I didn't charge it via this way when I first got it I just put it into the car after my old battery had a bad hold of charge.
Thanks for watching! I'm not exactly sure the reason for the 1-2hrs after showing 'FUL', but I figure it's to do ensuring the capacity reaches 100%.
If you feel, the Bosch is not holding a charge well, it may either have some level of sulfation or there may be a parasitic draw on the car battery. As a next step, will recommend you use the repair function to charge it for a minimum of 8hrs. This should address sulfation if present. You might find the new video I did on the Foxsur charger helpful. Also covers some information and tips on battery maintenance in general. Link below:

@@DIYAutoworksNG Thanks for the reply, just watched your new video and Liked :) !
There isn't a parasite drain as far as I am aware, though it is recently a brand new battery I am willing to give the pulse a shot as I am charging it indoors and cannot bothered to take it out again, currently I have completed the charge process and left it on FUL for approx 2 hours now is it safe to then put it on pulse? As it doesn't mention if it is after you have fully charged it.
Once the 8 hours have elapsed do I need to then put it back into normal charge mode OR should I just put it back into the car as is fully charged?
Thanks for watching and liking!!!
It's safe to use pulse right away, the pulsing hardly raises the temperature nor does it lead to overcharging. Besides the tool has overcharge protection. Pulse mode also charges the tool so no need to switch to charging mode in the end since you've already charged it. Even if you do, it will just provide float charge which wouldn't harm anything. Just keeps it 100%
@@DIYAutoworksNG ah right I understand that makes sense I was worried the pulse might do damage but come to think of it the normal charging is more likely to if you compared both modes.
I was concerned the battery might explode or something just my fears as I don't know much about electricity lol!
I ended up just putting it in the car without pulsing it and it worked in fact the start up was a fraction faster compared to before, I wonder if it will always be like this OR once it drops back to its baseline it will stay at that baseline if that makes sense so back to over a fraction longer to start. Just curious
Lol. Totally understand the uneasiness about electricity! I still put mine in plain sight while charging. Lol.
If you do not drive stop-and-go traffic or leave it unused for prolonged periods of time (and the battery is still healthy), it should stay the same. If it does drop again, just use the pulse mode to ensure sulfation, if present, is dealt with.
My foxsur battery charger the fan doesn't come on when it's charging it just ticks like a clock is this normal does anyone know. Any advice greatly appreciated
All batteries I can lay my hands on are full, so I can't do a proper assessment. I was just able to use repair mode. On repair it ticks, turn on and off with the pulses delivered by the device. You can also feel the air come through the vents with each pulse. Are you able to feel any air? Will be on the lookout for a discharged battery to check the other modes.
One question: I have been using this charger, since January of this year, in a 3 y.o. Lead Batery of 700 AMP car battery, because it was waking up in 11.9 volt and didn't star the car. The fist time revived with the repair mode for 4 hours. Since then I was doing a repair charge of 4-6 hours once a month. The other mode doesn't activate: shows FUL even if the charge is low, so I can only do the repair mode. But in the last two months the battery loses its charge overnight. I repair for 30 minutes and I can start the car, drive, and keeps good for about 6 hours. Any thoughts? How can I improve this? A repair charge of 24 hrs? The longest I have used that mode is 8 hours and still loses the charge overnight.
Most likely the battery is bad. You may have to leave it on repair for much longer than 8hrs. Twice as long, but again, I think it's probably badly sulfated.
Is it possible to use this pulse charger on an EFB (start/stop battery) battery?
The documentation that came with the charger did not specifically list EFB, though it specifies flooded batteries as supported. EFB's are a type of flooded batteries. Hope this helps.
Nice to chime in. The documentation on yours seems updated. Mine didn't lift EFB but I've certainly used on EFB's
I have a question about this product. My battery chamber has expanded thats the problem. Will this product work out well?
Swollen batteries are not good and should not be recharged. This product will not work. There's also a risk of explosion in charging swollen batteries.
you can not clearly say it works repair pulser or not??? I have seen many videos but I could not understand if this feature finally works if you have something more in this regard tell me please
The repair/pulse charging function definitely works. It is to be used when a battery has developed lead crystals on its plates and is not able to receive a charge (usually a battery that has sat with a low charge for a long time). Pulsing the charging breaks down these crystals. It is also the preferred charging method for smaller AH batteries. I have used just this to bring back a power generator battery which the service man said was no good. It is still serving me many months after!
mine doesn’t flash but looks like it’s charging ?
If its this exact brand, it should be flashing except when the battery is full.
my charger makes a crackly electric noise like its shorting, or like crickets in the grass, does yours?
Yep. Though not audible from a distance except I put the fan vent against my ear. Is your really that audible?
@@DIYAutoworksNG when it was first turned on and sometimes when switched over from pulse onto charge, i can hear the pulse noise also, but this sounds like it should do i guess
Yea. Sounds normal to me.
Thought you are in Nigeria? Why is temp reading 5 degrees?
I did this video during a trip to the UK.
Could you have charged the battery while it was still in the car?
Yes it is possible to charge the battery in the car. You will need to determine if your car is positively or negatively earthed. Most cars a negatively earthed. In such cars connect positive lead from the charger to the positive battery terminal, and the negative lead to the chassis of the car away from fuel lines.
The reason I didn't charge in the car was because the leads for the charger are really short and my power source was far from the vehicle.
@@DIYAutoworksNG Thanks for the reply; others have mentioned this, and I was unsure about why it would be necessary. Thanks for posting the video too!
Does pulsing stop automatically for car batteries?
Haven't had the opportunity to observe this. Have had power cuts during the repair processes I've done. However, the manual says it will switch to standard charging when repair is complete.
@@DIYAutoworksNG Manual says pulse mode will stop after 24 hours irrespective of the state & type of battery. Thus confused.
Yea. I think I'm mixing the info with the manual of a different charger that I have. Should be as you stated. I've never done a 24hr repair so can't confirm by experience.
@@DIYAutoworksNG Yes the manual is confusing. The charger is supposed to have overcharge protection, i.e. it's supposed to stop charging when full. Yet the manual recommends to keep it in FULL state for 1-2 hours. Not sure what's the benefit, since the charger stops when full !
That 1-2 hours is just part of float or trickle charge which is charging the battery at an amperage equal to its self discharge rate.
Can you just leave the battery in the car and charge it?
Yes it is possible to charge the battery in the car. You will need to determine if your car is positively or negatively earthed. Most cars a negatively earthed. In such cars connect positive lead from the charger to the positive battery terminal, and the negative lead to the chassis of the car away from fuel lines.
The reason I didn't charge in the car was because the leads for the charger are really short and my power source was far from the vehicle.
@@DIYAutoworksNG how can I tell if my toyota mr2 is earthed?
Check the battery terminal that has a lead attached to ground (chassis) of the car. That's the terminal that is earthed.
Your foxsur battery charger still functioning until now ? June 2020
Functioning like a champ. In fact just used it 2 days ago on the 9AH battery of my power generator.
Nice
How long to charge?
It depends on the capacity of the battery. From the manual, a 60AH car battery will take 13hrs. Smaller batteries will take lesser time, 20AH takes 5hrs...
So why do you have to take the battery out of the car? It says that in the directions manual too.
I bought one (different brand but exactly the same as yours; same Chinese factory) because the battery went dead in the car the other day and there was no one around to give me a jump and we live in a really small town in Colorado. So I ordered one of these for emergencies
I took the battery out because the leads of the charger are really short and I didn't have a long extension cable to charge in the vehicle.
I have a charger like this from lidl but it won't charge a fully flat battery. Stupid smart charger.
Oh gosh. Sounds like it's past the return period? One thing that can make chargers not work is if the battery has leaked out its electrolyte...
@@DIYAutoworksNG no seemingly these smart chargers won't start charging a completely flat battery unless is has a little bit of power in it. How stupid.
@@martymartin2894 You can fool the charger by connecting a good battery to the flat one. Once charging begins, you can then disconnect the good battery.
Thanks for this!
@@fungames24 do u connect a charger to the flat battery at the same time as the good battery or do u just hook the 2 battery's up and leave them for a while.
I used one of them on my new gel battery that went flat in the cupboard ...it never did jack as i had to bin the battery as it would not charge after 2 days of being on .....cheap nasty rubbish charger
Sorry to hear.
So the product doesn't claim to repair any dead battery. If electrolytes are depleted, it won't work.
If charger is bad, why would you throw away battery? Would have made more sense to throw away charger.
@@fungames24 i could not get the battery to charge as it was dead flat ...the charger works but never got the gel battery to start charging ...from what i have read they say a gel battery only last so many years and mine was 7
The 7 years is the reason why the charger didn't help. This one is past its life expectancy.
@@DIYAutoworksNG yep i recon so : )
4 degrees and no socks ???

I am like you. Car battery is dead. wont even open my doors. All this due to lockdown and virus crap. Im looking at these little things.
I feel you. This is really needed in times like this. Had to get my battery out of the car the other day and give it a good charge. Hope this virus goes away soon.
@@DIYAutoworksNG Horrible pal without car. Its like having 1 leg missing. Cant go out. Cannot drive as battery dead. I managed to find one of these last night on Fleabay just hope it arrives quickly. Thanks for your kind words sir, all the best.
All the best man. If you own a multimeter, see if you can check for parasitic draw. It's quite simple, tons of videos on UA-cam.

Wont work when battery is really low because charger doesn' t kick in below a certain voltage. Useless video!
I wouldn't call this useless at all. It has already paid for itself by saving me from replacing a power generator battery that the technician vowed was done for.
The manufacturer does state that a minimum of 8volts is required for a 12v battery for this to kick in. Such deeply discharged batteries can still be charged with this tool assuming you have a second healthy battery of similar capacity. Connect positive to positive and neg to neg, then connect charger to the deeply discharged battery. It should then charge. (I don't recommend this though to anyone who doesn't understand battery charging dynamics)
@@DIYAutoworksNG But it doesn't work for a dead or half dead battery!
@@DIYAutoworksNG But you have nevertheless given a good idea with cheating the charger with a second battery! I will try it and look if it works! You're a smart guy, I must admit! Thanks! And if it doesn't work (depends probably on the sulfatisation of the cells), I'm where I was!
We have a deal! 😂
@@DIYAutoworksNG I never knew that. Glad I saw this comment as it's right at the bottom. Thanks.
