I just upgraded to a new 2011 MacBook Pro (8,2) from an old 2006 model (1,1), but am trying to keep the '06 ready as a viable back-up (as much as it can be with broken wi-fi). The biggest issue I'm facing with the '06 model, though, is battery life because-- I admit it-- I totally dropped the ball on keeping it calibrated. According to coconutBattery, current capacity is 98 mAh down from an original capacity of 5500 mAh. Plugging it in yields a nearly perpetual red "charging" light and the menu bar charge display stays at 0% (Coconut says 1%). I can resign myself to that model being perpetually tethered to an A/C outlet, but if something can be done, I'd like to correct my earlier mistakes. Which brings me to two questions. 1) Browsing Apple's Store, I see a replacement battery at http://store.apple.com/us/product/MA348LL/A?mco=MTY3ODQ5OTY Is this compatible with the early (1,1) Core Duo models of the MBP? 2) Would a new battery even help? I remember back in the day reading about how the connectors themselves could get damaged by not calibrating regularly-- is the '06 beyond repair? Thanks for the help!
