I'm about to put a late 2008 MBP back into service. Aside from installing a new SSD and RAM upgrade this laptop will need a new battery. Even though it had low charge cycles and excellent recharge capacity the battery in this MBP was taken out of service because it suffered from battery swelling. I see a lot of cheap battery options from companies I've never heard about before. I think I would rather go with a Newertech battery from OWC but wonder about compatibility with the laptop correctly reading charge states and cycles and charging properly. Are people who have purchased Newtech batteries happy with them? The knock-off brands are less than half the price of the Newtech, and about 1/3 the price from Apple, but they scare me. Another related question: has anyone replaced the actual Li-Ion cells in the original Apple A1281 battery successfully? Any links to sources for the raw cells?
