I have seen apple batteries only last for 300 cycles, i have seen batteries last for over 1000 cycles, its almost like a shotgun chance of how many cycles your going to get in my experience, I would visually check your battery to make sure that it is not swelling, sometimes they will do this when they are going bad but will not display any error messages or anything like that until it has swollen so much that it has crack a track pad and busted a few screws off the bottom plate, one sign that this is happening is that your track pad is not acting correct like highlighting stuff your not trying to, moving icons that your not trying to, selecting items while you are just scrolling your mouse across the screen, that kind of stuff
This is the exact explanation of that error code
PPT004 The battery requires service. The battery is not functioning normally, though you may not notice a change in its behavior or the amount of charge it holds. You can continue to use your battery before it’s checked without harming your computer.
Contact Apple or take your computer to an Apple Authorized Service Provider or Apple Retail Store to determine which service and support options are available.
