In order to check and recondition the battery's cell we'll need to get at it directly, bypassing the control systems. This means we will have NO short-circuit or overload protection, so take extra care.

Peel back the black insulation to expose the cell's terminals (Never let these points become electrically connected) and check with a voltmeter.

If you see a voltage greater than about 4V, the RAID Card is charging the battery but it can't tell when it's finished. Proceed to step 5.

If you see a voltage significantly less than 3.6V, then the RAID Card is not charging the battery. Proceed to step 6.
