Why does my brand new battery drain very quickly?
I recently replaced the battery on my mid 2009 MBP with a brand new OEM battery from IFixit. I charged the new battery to capacity and then allowed to continue charging for about 10hrs. I then allowed the battery to fully drain (which happened relatively quickly) and then charged it again to capacity.
Now even without intensive CPU usage the battery is draining very quickly and probably lasts a little over an hour. I reset the SMC and PRAM but this did not seem to help.
Can anyone shed some light on the situation?
