I suppose that such a damage condition can result from overcharging the
battery, or from charging it too fast. A bad voltage regulator could
be at fault.

I have experienced the same even with car batteries measuring slightly
less than 12.0 volts. They might last for about six more weeks; however,
if you have a Ford, they won't work at all. A Ford insists on having a
battery that is up to snuff.

This is perfectly true if used for a high current drain application, such
as in a flashlight, but they will continue to work for considerable time if
used just to power a CMOS or a calculator having an LCD display.
