I asked in this thread but it might have been missed? https://www.bobistheoilguy.com/forums/ubbthreads.php/topics/5233378/is-my-battery-toast#Post5233378

I recently just pulled my battery prior to storage and while checking the water level, I noticed it was down but still above the plates slightly. I added approx 450 mils total to all six holes.
When I put the volt meter on it, it read 12.56. Should I trickle charge it because of the new added water or just leave it alone?

Yes always charge after adding water. If the battery is still in the car though, you can just drive.

Thanks guys. I'll put my Battery Tender JR on it tomorrow and leave it until the light turns green or the charge increases somewhat. cheers

If you are going to store the battery, why not just leave the Battery Tender on it 24 / 7? That's what they are designed for. They will not overcharge your battery. I have a lead acid car battery I only use to operate a clay target thrower. It has been on a Battery Tender Jr. for the last 3 years in my garage. It maintains a 100% charge without me thinking or worrying about it. Yours will do the same.

Do not add water as long as it is over the plates. Some batteries will when charged have a water rise and throw it out making a mess. Contamination from water is a source of battery failure, use only distilled.

That's how I was taught to maintain industrial batteries. As long as the water is covering the plates, you charge it first then top off the cells.
