Highly unlikely.can this battery be able to recovery?
Seconded.Highly unlikely.
Sounds like a ruined cell.
So do I. I'm keeping them for when I need lead to make shot for reloads.I have quite few of that kind of batteries.
How does one do that with a sealed lead acid battery?I did refilled them with distilled water.
There is usually a plastic disk on top of each cell that you can pry off. Under that is a rubber cap that can be pulled off reveling the filler hole of the cell. I have managed to get some cells back by putting battery acid in the cell, but mostly they are dead.How does one do that with a sealed lead acid battery?
