I had a dead PC motherboard and unsoldered a coin battery holder and the battery. The backup battery's shelf life is the limiting factor so the little coin battery will outlast the AA cell. The battery only backs up the memory and there is not much of a load on it, the self-discharge load is likely higher for the alkaline cell.
