Introduction
Underneath the pretty aluminium box, Apple's RAID Card batteries are just bog-standard lithium ionpolymer cells with some control gear.
When they fail after a year or two in service you can bet the £££ you'll fork out to replace it that the cell isn't dead, but instead has got itself into a stuck state where the RAID card is confused about what to do with it.
In this guide I will outline how to verifyopen up the batteriesbattery and recondition them soor even replace the Xserve will be able to cycle them properlycell, at significantly lower cost than buying a new battery.
