Actually, that is a good indicator of a near-dead battery. It will also charge rapidly to full voltage. Of course you aren't actually storing much energy, just moving the tiny remaining bit of un-sulphated lead back out of solution onto the plates. Or in other words, you have a 1 Amp hour battery in a 90 Amp hour case.
I'm betting you were coming to that conclusion.
