Dead Battery

[Ginger]

...and it's not possible to drain a battery so low that it becomes damaged?

I contend that it IS possible.

I've had both broken batteries (from rectifier damage on the VFR) and completely dead, busted nuts, repeatedly drained to the core batteries (from my Accord). In both instances the battey COULD NOT be jumped.

I think it IS all semantics, though. A dead battery is the same as a broken battery to me... if it won't hold a charge it's got to get replaced. Dead, broken, I would have used them interchangably all day long if you hadn't made the distinction.
