    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

    Age, pure and simple. Batteries don't fair well over time, even if correctly stored, it`s their nature and the chemistry within.
