My MacBook Pro battery is caput. No longer. It's a dead battery. Any recommendations on replacement batteries? The standard Apple replacement is kinda spendy and I've seen "high capacity" 3rd party batteries at an almost 50% discount. Does anyone have any experience with 3rd party batteries or is the Apple one the only way to go? I really don't want to fry my MB with a garbage battery even if the thing is starting to get long in the tooth.
