Possibly the best you tube on batteries ever! Thank you so very much.

Best explanation on lead acid battery restoration I've seen. Too many of these videos have only instructions without the why behind it. Understanding the concepts allows one to modify certain steps when thrown curve balls. Bravo!

this is grat well done.. dont listen haters. . you dont need 600 amp if you use them for solar.. yes maybe this method cant wotk for car cold cranking amps.. but imagine 10 or 20 of them buying them for 7 dollars per pcs for scrap.. you only need to work a little bit and yeah.. you have let say 20 batteries * 80 amp hours 1600 amphours ar 12 volts equal to 19200 watthors.. 19.2 kwhours lets say at the worst case you have lost the half capacity because of restoration (they are not new) yes you have built an enotmous 10 kwhours battery bank for 140 dollars..

I enjoyed the video. For those of us who don't have a charger with an equalizer option, but do have a variable DC power supply, what is the ideal Amp setting for a single flooded battery?

A battery with one dead cell will run your 12 volt house lights for years, from solar panels. I've been using my dead cell car battery for 22 years still runs the house lights and the tv.

This is great info, thank you!

This Guy really knows what he is doing! How do I know? I am a retired Motor Mechanic with decades of experience.

Thank you, for a great and informative video!

VERY EDUCATIONAL FOR THAT

Great Ideas to recovery dead battery Wow!!! Go Ahead and working my dead battery recondition

lol Thank Man! you brought back good old memories of my napping days in school.

As long as old batteries can hold around 12 volts, they can still be used to power LED lights even if they won't crank a car engine.

Very educational Thank you!

what you showed is kinda expensive for now what i'll try is the baking soda and distilled water i hope it does help.

I wonder if ultrasonics could help to remove any calcification?

good video.thanks

Can I use oil cooled welding machine to revoke old dead battery back to life?

i picked up 2 new,unused diehard deep cycle marine batteries,i was told they have sat for 5 years,he charged them,and i multimetered around 11.5 volts,fluid levels are even,had auto parts store try to check them and found out they are from 2009,kinda mad about that but ,i charged them over night and tested 12.8-12.9,put one in my truck and the battery meter in dash is on the low side,shouldnt it show on high side being it was still a little low,could i just buy some more acid and drain whats in there or do i have to flush with epsom salt and distilled water trick

Will the fully automatic charger allow force charging at 40amps? I can seem only to find the automatic computerized ones everywhere. I can't find one like yours at my local dealers. Also I heard some say I should be looking for a 200amp DC 12 charger (which I can't find one anywhere at all, only 200amp or 250amp 5 second boost on ignition detection) to do it as well or 40amps is good enough?

good info. thanks

Will they work as solar storage batteries?

I've had little to no results from an electronic pulsing desulfator but I've managed to more than double the capacity of old batteries by adding about 10 mls of PURE sulfuric acid to each cell then overcharging it as described in this video. If you're going to try this you MUST use rubber gloves and eye protection and I recommend a hypodermic to add the acid.

Hi I got a used Seal Lead Acid 100ah and when i open the lid it is dry, should i top it up with a normal battery water? Even the battery is dry it still remain at 12.7v . Should i leave it as it is or add battery water into it? A Seal Lead Acid is also known as a AGM battery right? A Gel based right? A gel based would also required battery water too, during recovery?

Massive thanks for the information you share. At the end you still buy new batteries if it does not have enough amps to start a car.

Good explanation to the point!!!

Sulfated batteries use a 200 amp charger for 10-15 minutes, then stop and let battery cool for 1 hour. Then repeat process, maybe 5 times or so until all cells are alive and bubbling

Good to know .

Hi, where did you get the meter which shows the cold cranking reading, or rather which make of meter is it

know this is not good enough for to start a car, is it good enough for a simple solar charging backyard light? (deep cycle)

For equalization in place of a charger, do you think a 100 watt solar panel putting out 18 volts @ 5 amps would be suitable?

Deteriorated positive plates are irreversible. What you call hard sulfated plates are most definitely reversible as long as the plate is not deteriorated. However a purpose designed charger is the key and you don’t have one. They are available but pricey. The only people I know that have them are battery manufacturers and a few industrial battery repair shops. It ain’t rocket sience but it ain’t something you hook up and leave on for days either

just a quick question, after replacing the salt solution. how long doesnt the battery lasted before u need to replace the salt solution ?

I'm wondering if you lose water normally over a couple years or is it more serious like you said, alt boiling off water?

Outstanding information. Thanks!

Equalization achieved by sometimes using "epson salt" or "aluminum sulfate". When is one used vs the other?

7:24 What's the difference between warm and hot? I'm doing this to a bus battery, about the size of three car batteries. The fluid is at 100 degrees. What's the highest safe temperature?

Thank you for uploading this presentation. I will try and use your technique shown here to bring up one of my old battery to working condition. But there is one thing I am puzzled. Provided bring the battery back up to required voltage and able to crank the car with up to par current, what assurance will I have that the battery will operate all the time while on the road driving or not. It could possibly loose charge so slowly and alternator might not able to charge it up and could get stuck in the middle of desert. I don't believe once the plates are damaged, they will never be like new, unless change them with new plate, the capacity will not be like new. Therefore I do not believe any restored batteries with some form of plate sulfation just can not compete against new batteries unless damaged plates are fully restored like new to provide high degree of internal reaction so the battery will able to put out enough CCA and voltage at all times for extended period without worrying.

We use a DC welder and a length of cables to be away from the battery, hit it with 44 volts, 120 amps for 1 second intervals, about 4 then put on charger. You'd be shocked how much crap comes off them plates in a few seconds.

A lot of today's batteries no longer have caps! The battery companies have appeared to have outsmarted us.

You did a good job with the demonstration & explanation. 👍 I am looking for a way to re build batteries. I am all about recycling repairing & repurposing plus a "little frugal" LOL. Around 55 years ago there was a guy in PA that use to sell used batteries that he rebuilt. Well we were on vacation & my uncles car's battery died. Back then there wasn't all these auto parts stores & we were in the Pocono mountains, so we bought one of his batteries. This was for a big ford with a V8 & never had an issue with that battery. Anyway I a looking for a method to remove damaged cells & replace with good cells from another battery if I get the time. Seems like there is always a project that needs to be taken care of. If you should make a video doing this let me know. Stay safe, Joe Z

Is there a safe way to get into a maintenence free battery?

The link in the description leads to a (sales) page with a video that has no progress bar and promises a "short presentation" of the "EZ Battery Reconditioning™ system" (turns out it's a paid course, of course)... after about 10 minutes of endless talk with no useful info I finally gave up and googled it. The 1st page I found which offered a review of this "system" stated that this was a $47 course, and laid out the "new system", which turns out to gives no more than some of the free advice on youtube, and additionally requires that you purchase test tools, and possibly some chemicals etc... NOT COOL!!!

Problem with that harbor freight meter is that one mistake and you killed it, but if you buy a better meter they are more forgiving.

good video but it is not sold better repair or buy it again because here in venezuela everything would be used almost at the same price of the new battery

Dump the acid out completely and take regular tap water with baking soda and fill each cavity and rock it back and forth let sit for a few hours and dump out completely , do this 4 times , be careful wear shitty clothes, gloves and glasses, and then mix epsom salt with water fill the cells up as usual and recharge again for 72 hours. Load it down with two headlights for as long as it takes to get the voltage to 7 volts... recharge again. Battery should come up half ass and useable to 12 V with cranking amps pretty close to 80 percent or better of what new was.

Here,s another great video on how to recondition your batteries!!!!

You can only turn the post cleaner clockwise, to turn both ways will destroy it.

Just to clear up the hydrometer, what it does is measure the specific gravity (mix of electrolyte) a good mix is 1260 on the hydrometer the best way is to empty out the old electrolyte wash out with water and fill it up with new pre mixed electrolyte

what water do you put in

Hi. Are you David Voss? Cause you sound just like him.

man at the battery store told me to use Epsom Salt = Magnesium Sulfate, to help clear the plates.

My factory installed batteries, both Panasonics in our Toyota and Honda lasted 16 and 14 years. Why worry about it.

My question is can I use a good battery hooked in parallel with a bad battery to burn off the sulfation of the bad battery, and I believe you answered my question, yes.

How do you know when to put the Epsom salt in? Thanks

so where is the answer to all the recondition vids that uses new acid?

sulfation will also disintegrate the lead after a period of time. Those meters are free with coupon from Harbor Freight.

At time stamp 10:31 the red Harbor Freight (Cen-Tech brand) meter is compared to a green digital multimeter. The statement is made: “You can see the Harbor Freight is fairly accurate...” That statement ASSUMES the green multimeter is also fairly accurate. It is a reasonable assumption, but there is a very SLIGHT chance the green meter isn’t accurate as well. My car has a thermometer that shows the outside temperature on the dashboard; When I compare it to thermometer readings shown on a bank’s marquee and the two temperature readings disagree, which thermometer is more accurate? Or I drive past a radar instrument set up by the police that flashes my car’s speed, and my speedometer shows a slightly different reading, which one is more accurate? BTW: I have several of those Harbor Freight multimeters and have compared them to several of my other digital and analog multimeters and I agree that the voltage readings at 1.5 V DC, 12 V DC,& 120 V AC are fairly similar among most of the multimeters including the Harbor Freight ones-but I had one more expensive meter that wasn’t. This reminds me of the state trooper who’s radar gun clocked me at 74 MPH while my speedometer read 65 MPH.

If it hasn't been sitting for long (1yr/2yr) and has low use/abuse. You can probably check the cells and see if they need distilled water which would be a quick fix

What about battery pulse repair?

Not sure what this "restore it 100%" nonsense is about. Once the positive plates have corroded away, it doesn't matter if what is left is sulphate, once the plates have turned to sludge, the battery capacity decreases pretty much in direct proportion. Sure sulphation CAN be a problem on a newish battery that has been neglected - but if the battery is many years old, the positive plates will be mostly gone - it will show a normal voltage but underload will collapse quickly. Once that happens, you either rebuild the battery with new plates (perhaps worth it on a 1000A 2v storage battery) or you chuck it away OR you can keep it as a door stop or perhaps a 12v battery to keep a shed light on for a few minutes - with a solar panel on the shed roof to keep it charged up. Used like this, it doesn't matter if you 90AH battery now only has 10% of its positive plate remaining as 9AH at 12v will power the 12v LED light for ages. But once the plates have corroded away to almost nothing, you are NOT going to restore it - let alone to 100% :(

The subtitles of the voice over contain dozens of mistakes, eg he says for 8 hours, which is shown in the subtitles as 48 hours!

OMG!! Mr. Rogers is it really you ???

I am at 7:44 and am just wondering if he actually refurbishes a battery or just talks about it for 15 min?

The real goal of this video is to sell you the useless instruction pointed to by the web URL at the bottom of the video frame.

can you make a video please how to use 20 bird scooters to make a solar battery ?

yes and now give em hell from a starting motor or at lower temps, it won't perform

can you really make a sulfuric acid from Epsom salt and revive a battery that's been turned upside down and lost all of its electrolytes

Never mind, I'll just get a new battery.

Sometimes I trick my charger by hooking another battery up in parallel and it recharges the battery. And Sometimes it works🤷‍♂️

Don't click the link! otherwise good video

Nobody speaks about the oxidation inside a lead acid battery?Why? The Led turns into mud.

Don't think the Big Boy Battery Companies are losing sleep over this...

A bad battery will destroy your alternator which will destroy your new battery.. Don't get caught in a loop!

I laugh when I see this silly load tester being used as some kind of reliable loading device. It only loads on a good day to about 60 amps ! Get a real adjustable carbon pile put 2-3-400 amps on the battery read the amps / volts and you know what you really got.

I myself am a battery. And this guy just wrong

9:16 Here's the answer to a question asked in the comments of this video: kzfaq.info/get/bejne/m6imdKeJuNWyZY0.html about the WRONG reading on a Cen-Tech charger.

i like the color of your multi meter....hehehe

Lol “I believe the acid has something to do with it” Ummm Ya think

so...if im getting a good connection the car wont start? wtf did i just hear? what is a door nail?

Hi I'd like to say your methods are sound. I have worked in the battery industry for well over 30 years mostly in the industrial business ie: fork lifts, mine locomoties and heavy duty marine. I have not spent money purchasing new batteries since I can't even remember when! I had the luxury of being able to dump out the old acid and filling up with distilled water then trickle charge till the voltage rises to a preferred voltage of over 2.1 volts per cell then dumping that and filling up with 12.35 sg acid and then charge up with a normal charge,then load test over a set period and recharge again. I realize many people won't be able to do this and that is why I like your method! I would also like to note that you should never put a battery onto concrete floors or blocks!!! That's a big no no in the battery business and a quick way to drain your battery! Keep on posting videos like this they're informative and bang on the money!

Click link for skill

Here's a method a little more intense than this: kzfaq.info/get/bejne/ir-Iq5phsteuXWQ.html

Start with a fully charged battery that's been off the charger for at least a day and using a carbon load tester at 1/2 the listed CCA on battery tells the real story of battery condition.

I got rid of my High Frequency Stimulator when I got a divorce.

and is as long winded as that fellow i hate those commercials

you just need to jump it and let the alternator do it's magic - it will desulfate it over a few days

Has anyone told you that you sound like Dick Cavett?

interesting points ,if anyone else trying to find out how to recondition used car batteries try Panlarko Recondition Planner ( lovy.biz/zrsy ) ? Ive heard some super things about it and my m8 got great results with it.

Wow you took proven science and called it "your theory and your belief" - Sorry but batteries used to be refurbished, until it got so cheap to replace and recycle them.

blah blah blah blah 10% content 90% blah

Bullshit. The average person won't go through all this crap. He'd go to the garage and pay to have it done. The body-shop businesses don't want you doing everything yourself. If you could, they'd be out of jobs.

Just buy a new battery you have warranty ..
