2008 MBP says "replace battery now." Bulltish, I say. It's had 3 charge cycles & its holding it maximum charge level. This is a new battery. The old battery that's got just over half the amps of the new one and lasts for about an hour (the new one goes for at least four hours) is regarded by the system as "normal" condition.
Nope, not replacing a perfectly fine battery.
