This is especially true of sealed batteries like Optimas. If they get too hot, the safety vents pop and it's no longer sealed anymore. Once water boils off this way, there's no way to replace it. Generally speaking, sealed lead acid batteries will not tolerate as much charge current as non-sealed ones. Gel cells, in particular, usually have some pretty specific restrictions on charging conditions.
