Hello! I wanted to replace the battery in my late 2008 MacBook Pro. I purchased a brand new, sealed, genuine battery from an online dealer.
I installed the battery yesterday and charged it. It took a very long time to charge (around 10 hours, starting at 0 percent). I then disconnected the charging cable to allow the battery to run down (in an attempt to calibrate it). I didn't use the computer (only had safari open) and just left it with the screen brightness turned down all the way. When I checked it around 5 hours later, the battery was dead!
I'm charging it again now, and it is charging more quickly, but does anyone have an idea why it didn't keep a charge? Are these batteries just too old? I assume this battery had been sitting in its box for a very long time since being manufactured so maybe that's an issue?
Any ideas? Fingers crossed it holds this charge.
Thanks!
Geoff
