I think those suckers take readings of the voltage, though if it's higher or lower than the stock battery it may freak out and not properly condition power / recharge if there is a failure. Not really a memory issue, but how the hardware is on the board.

It's worth a shot if you have a spare laying around. Worst thing that can happen is that it fails... well that or explode. I suppose exploding would be the worst.

If it doesn't work, call a battery store and check how much a new cell at that range would cost.
