Jenny has a 6 month old Powerbook and about 2 months ago the charging system started acting flakey. You’d plug it in, charge it up to 100%, unplug it and sometimes the battery reading would almost instantly go to 0% and then the system would go off (as it had no juice).

So I took the system to the local Apple Store and at the, um, Genuis Bar, the guy acted like batteries on Apple laptops don’t last that long. He said he’s definitely not suprised at batteries that last 18 months or less!.

System is under warrenty so we’re getting the $190 battery replaced for free—but if you’re to belive the guy when you buy a system from Apple you have to budget for an almost annual battery replacement!.

Could this be the next Apple battery scandal a la the IPOD battery fiasco?

PS Apparently lithium batteries have a very limited life span.
