I have a similar question, so found this in a search. The difference is my battery is nearly 10 years old, but it works fine and holds a charge for 4-6 months, still.
(I finally developed upgrade-itis, but hate the idea of tossing/mothballing a perfectly good battery, unless it is near EOL.)
Apologies for the necro-post.
