Don't be quick to throw out that battery! Just worked this again this week. I have had seval 12 v batteries act dead after sitting in a non-running vehicle many months or years. This time it was my JD riding mower 12 v. Hadn't run it since June. Battery acted dead. Would not hold a charge after several hours. Used starter mode on charger to start mower, but would never restart. Here is what I do. I took the battery out (which I did not do in my dump truck or 4X4 Pick up). Put the charger on 2 amps and let it charge for a week. Charger LED indicated full charge after 2 hours, but I leave it on 2 amp any way for a full week. Put the batery in the mower yesterday and it starts every time. Acts like a new battery. 4X4 had sat for several years, till I did this to start and sell 4X4. That was two years ago. Buyer still has not replaced batteries.

Sounds like it worked a lot better than the Mikrowave oven idea did with Sis's battery, but I don't have a battery charger with LED. I thought the Led was part of the battery on the inside of the case from what I read about the sulphides getting stuck in the battery and making it stop working.

I gotta ask though is there any chance the battery is going to blow up with that LED charger? Just went through that and I tell you it wasn't one bit pretty. Sis is out of work for a while at least till they rebuild the choke & puke kitchen, and that don't look like its going to happen overnight. On top of that she can't collect unemployment cause she was working under the counter as they say, so Sis ain't got no income comin in. That means she can't even afford a new battery for her car, not even at Walmart, and batterys for her car ain't exactly what any working person would call cheap there either.

Her battery that blew up came out from under the back seat of her car you know, and from what I was able to resarch out down to Walmart, it must be some kind of special battery. It did have sort of a padded bag around it, sort of like the insulated bags they used to give you at the store to get your ice cream home without it getting all runny, but ain't anybody been able to find that bag since the Choke & Puke went kaflooey. I climbed in there myself looking, even thought it might have got in the dishwasher, but it wasn't. Rodney swears he took the battery out of the bag, so it should still be in the kitchen, but I wasn't able to find it. I did make sure I put all the screws back in the plywood they got over the doorway to the kitchen when I was done looking, figured there must be some reason they walled that kitchen off.

Since Sis can't afford a battery, she and I were talking, and I figured just about any 12 volt battery will get her car started if she sets it in the back seat and hooks it up to the cables. Only thing is she ain't gonna be able to get the back seat back in. That probably won't be a problem though cause nobody has ever ridden back there. I'm thnking maybe she should put a box over the battery though so she can fling stuff back there without any problem of her stuff coming in contact with them battery terminals and shorting em out. Sis left word with the fellow who works the fuel island at the truck stop to have the fellow who junks cars give her a call so she can see if he got a car with a good battery she can buy from him cheap so we can get her car back on the road.

Battery charger is standard 12v/6v 10a, 2a and starter mode Harbor Freight cheapy. LED just lights up to indicate "charged battery". Fired up mower again today. Still holding charge.

Hello:

I suggest investing in BatteryMinder Maintainer/Desulfator/Conditioner

Automotive Battery Chargers | Battery Chargers by BatteryMINDers.com

I have used it on a number of batteries around the house. Some I was able to recover and some were dead. This technology will indicate which and if the battery is still good it will recondition/desulfate it. Battery chargers may charge temporarily but if the battery is gone it will not hold a charge.

The equipment is a bit expensive - about $130 - but I think it is worth it. It is flexible and accomodates a number of battery sizes and types.

What a coincidence. I put a battery on charge and left in in the garage on auto charge.
It read full so I hit the check charge amount button ant it was at 12.0, then started charging again ...???? Next day I did the same thing but now it showed 12.2 volts, and started charging AGAIN. Repeat next day showed, 12.9, repeat next day showed 13.0. next day showed 14.8, and again stated FULL and would no longer charge.

So I did the same thing with two other batteries and the same thing is happening, they are all crawling up in amps after reading full.

I read here:
HandyBob's Blog

That ....Get a three stage charge controller that will handle the power from more panels than you buy and that has an equalize button on it. Equalizing is the source of much disagreement in the RV world, and I know you don稚 really need to do it if your charger is working correctly. Trojan Batteries says to equalize when you need to, based on a hydrometer test and I haven稚 had to since I set my controller to 14.8 volts.

I've tried battery additives in the past with limited success. I had a brand new motorcycle battery that I let sit for 2-3 years and it went completely dead. Tried the additive and it still wouldn't take a charge. I honestly can't recall what it was, but it cost around $10 and a new motorcycle battery was around $25, so it was a complete waste of time/money.

By the way, the little BatteryMinder with desulphator is on sale for $39.99 plus $5.99 shipping from Northern Tool right now.
