I turn my old one in for a $10 core charge refund when I buy a new one.

Starting with post # 7 in this thread I enlighten on the wonders of Epsom Salts in batteries.

I'm a true believer!!

Do a search for "recondition battery using epsom salt". I have had good luck so far with a few that failed after load testing. I didn't heat the epsom salt,I just put it in a bottle and shook it a lot. Only dumped out about half of the battery acid and topped off with mixed solution. Shook battery pretty good. Charged at 3 amps with an analog charger. Fully discharged by clamping 2 old tractor lights to it then fully charged again.

Tried it last fall on the two 6 volt batteries in the Dexta. Drained the old acid and and even flushed all the old crud out of the bottoms of the cells. Then filled them back up with the epsom water solution. At first everything seemed fine and I was a happy camper. As the temperatures dropped it became obvious that the batteries weren't going to cut it. Ended up replacing them with one large 12v and everything is good again. 

Personally I wouldn't waste the time again. In warmer climates it might work fine. One thing is for sure, it won't cost you much to find out if it is going to work.

Never drained the old acid - only poured the salt in dry and shook. 

Also, I never added water to a battery- only add more acid if needed.

I have a 50 bound box [jug] of acid I use from when a local auto parts store went out f business.  It was free, being haz-mat they couldn't just toss it in the trash and was glad I'd take it.

I am a believer in this process as well only I use sodium sulfate instead of epsom salts in the same amounts Gtractor mentions in the previous thread. I haven't had to replace a battery for years. One caveat, I treat the batteries as soon as I get them. No need to mix with water, the battery acid dissolves the sodium sulfate completely. :thumbs:

Have tried several supposedly battery revive methods over the years.  None had any good results if they had to site for a month without being used.  Also cold weather really took them down fast, no CCA  unless it was a 450 CA battery on a single brigs or something like that.  Quit messing with them and trade them in on a new Interstate and good to go.  MY dealer don't mess with the core charge or refund.  Just more paperwork for him.  Bring your old one back and set it on the ledge outside the front door.  Pay regular price for a new one and on your way.  Couple other places I buy the cheap batteries for resale tractor go the $10 route but it only cost me about $20 for anew battery that way.

I tried it about 6 or 7 years ago using directions from a youtube video. It didn't work, but the battery I replaced that one with still works like new.

I never had any luck reviving a battery with distilled water so just quit buying open cell batteries, they'd all leak acid anyway, rust out my battery tray, etc.  Now i buy the sealed batteries, they don't cost much and i don't have to worry about battery acid getting on the grass that the dog eats.

 

Just wondering how you guys dispose of old battery acid??

Pour a small amount in a plastic 5 gal. bucket and filled it the rest of the way with water. Then spread it on the gravel driveway to dry.  It's diluted down to the point that it won't hurt anything.

Most places that sell batteries will take you old one but won't give you the core charge. 

If your loosing that much battery acid you have another problem, like overcharging?   Batteries don't leak until they are damaged by some outside means.

Tried one sealed battery and never again.  No longevity, short on power to start with and short on capacity.

I have tried the epsom salt thing, with about 50/50 success rate.......got a couple of years out of them. 

I work at NAPA these days, so we have a skid of core batteries.....many of them have enough life in them for a garden tractor.

I can fit a car battery in my tractors, so use a larger car battery. They last for years.
