Battery question, continued

[McLoffs at aol.com]

I hate it when I hit "enter" before actually finishing my e-mail.

Anyway, as I started saying, I'm getting my motorcycle out of storage for
spring, and am having some starting troubles. I think it's the battery. I
took the battery out last week, topped off the water, and put it on the
trickle charger. When it was done Friday, it was showing nearly 15 volts. I
checked it again today (it had just been sitting on the workbench, not
attached to anything) and it's down to barely over 12 volts. I hooked it up,
and the battery alone won't get the bike started -- have to jump it.

Am I correct in assuming the battery is ready for replacement? It's about
three years old.

Thanks for your help, and thanks for putting up with a non-Audi question.
