"new" battery bad?

[flappinfish]

I have a 1.2 ppc G4 I Book running system 10.5.6. My battery died quite a while ago and I finally bought a new one last week. I bought the new battery from amazon.com It was billed as a replacement battery, I don't know who makes it. It appears to be exhibiting "bad" battery symptoms. Dieing while still holding a charge (first time @50% 2nd time @25%) and taking the system memory with it. When I received it I just began using it. Is there some proper charging method or something else I should have done to prepare this battery? Or is it just a crappy battery.

Thanks.

Return it. Even if you're not charging it 'correctly', it shouldn't be displaying the problems you outlined. Amazon are great with taking stuff back, you shouldn't have a problem.

If it's not an Apple OEM battery, you take a crapshoot when buying it.

See if you can return it to the seller, and take the cash +some extra to the Apple store and buy a proper battery.
