    I got a Service Battery notification today on my Macbook Pro. Do I need a new battery or can I reset something to fix this? I thought the cycle life for a Pro was 1000 and mine is only at 467.

    Any help would be appreciated! Battery info is below! THANKS!

    The maximum number of charge cycles is 1000.

    How old is your Mac?

    My battery gave that warning well before 1000 as well. Applecare had ended 2-3 months prior, so the best Apple would do was offer a 25% discount on a battery replacement.

    There's really nothing you can do. Either live with it or replace it. I went to Apple because I've heard too many stories about after market batteries not lasting as long. The choice is yours.

    Happened to me last year, had my MBP for two years at this point. Was going to leave it alone as it wasn't affecting anything, but I caused another thing to my MBP that I couldn't use it for a little while, and I wasnt charging the battery regularly at that point, so it died. When the other problem was fixed, I was forced to replace the battery. It wouldn't let me just use it with the cord (there's code or some sort of kext that kicks in and was using one of the two CPU cores to charge the dead battery. Correct if I am wrong. Couldn't use it as it was, so went to Apple store to replace the battery (at $140 was the cheapest option, 3rd party stores wanted $170 and up.)

    So...it happens, and the machine is running like a champ one year after the fact.

    The charging controller needs the battery to be installed, since it sometimes will draw power from the battery either because the power demand rises above what can be supplied by the adapter (rare) or because it's keeping the battery maintained (common), so the system will refuse to run without a battery installed.

    It also won't let you leave a dead one in there and continue using the machine since there is the possibility of damage to the system if the battery is in poor condition. Best to get it addressed by a repair place, or by Apple.
