So, just recently I was here asking about 3rd party batteries because I was thinking of getting a backup before a trip. Ironically, just now I noticed that my computer is now reporting that I need to "service battery" ... AGAIN. I had the battery replaced a little over a year ago and now there's another problem? What I'd like to know is if there is a known issue (known by users, not Apple) related to batteries in MBP 5,1? If not, what could possibly be causing these frequent problems??
