When to Replace Battery

[Apple]

When do you guys think it is time to get a new battery for my ibook? It is a 2005 model and after using a program called capacity meter, my battery is at 47% of it's old capacity. Should I spend the 70+ bucks on a new one now or wait until it is down even lower?

Really up to you, we can't really determine if your battery at 47% last long enough for your needs.

Seriously. Depends on your needs. Since I plan to keep my MB for a few years, I'll probably stick with mine until life dips below an hour.
