I accidentally spilled some of the battery acid from my car’s battery when I took it out from the car to fix something that was obscured by the battery. The battery got tipped over and I didnt notice, not until about half of the fluid spilled out. All the cells were affected. I added water and rec…

The sulfuric acid used in car batteries is very dangerous to handle. If you can find a source, you may get lucky and replenish the battery with it. But, for me, I’d just consider this battery toast and simply replace it. I don’t have the equipment to handle battery acid safely and it is just not wor…

The battery is done. You can add distilled water to a battery if the level is low because the water evaporates from the acid. But if the battery is spilled where the electrolyte is lost no amount of water will bring the battery back to life. You could go out and buy a motorcycle or lawn tractor bat…

Call around, you might get lucky. There’s also a product called “Liquid Fire”, which is marketed as a last-ditch drain opener for use when all else fails, but is actually concentrated sulfuric acid. As far as how much to add, I’m no chemist. You might also take it to a battery shop and see if the…

Not that I recommend it (sealed batteries are best for cars, IMO), but sulfuric acid is readily available at Lowe’s and Home Depot. They both sell marine batteries for use with battery-powered backup sump pump systems. Those are shipped dry and you add the sulfuric acid and water at home. It’s be…

Should you be daring enough, do be careful how you handle it. For instance, if you add water to the acid, it will boil violently. If you have to mix to get to the right specific weigh, carefully add acid to water - not the other way around. I’d just toss the battery and get a new one. Eyes and sk…

Its only 18 months old. Take it in and warranty it. The last I warranted,it only cost me $17 pro rate. That was 4 years on a 6 year warranty.

A real battery store should be able to sell you “Battery Acid” in a one quart or one gallon box. These boxes come with a dispensing hose attached…Handling the acid just takes a little common sense… But you have another problem…You must dump out all the diluted electrolyte from the battery before yo…

Some folks have raised the issue of disposal of surplus sulfuric acid, believing it to be a problem. You, George, have enough of a chemistry background to know that small amounts of acid can be neutralized with baking soda or baking powder from your kitchen. Once neutralized, the acid is totally s…

Since you can measure specific gravity (many folks don’t even know what that is) it is clear you have sufficient chemistry training and experience to continue with your idea. It ought to work. Don’t give up on it, and let us know of your success.
