Yep. Old news.

There ARE certain types of battery that are truly maintenance-free,
though. AGM (Absorbtive Glass Mat, aka "Gel Cells") like the Optima are
truly sealed and don't have any liquid water. You can still ruin one by
over-charging, which causes the electrolyte in the mat to out-gas too
fast and pop safety seal, opening the battery to air so that it will
dry out and die.
