> If this assumes an alkaline discharge curve then with a rechargeable it will think fresh batteries are at about 90%, which will rapidly fall to around 75%, and then think it is barely declining for a long time until the batteries are actually at about 10%, and then it will rapidly go down. It's a bit worse than that in my experience. Devices with low-battery warnings seem to basically show the warnings perpetually, never on truly fresh batteries but reasonably soon afterwards. In actuality, the batteries will last for months past that point. If the curve was like you describe, I'd expect to see low battery warnings less, not more, frequently with rechargeables than disposables. Still not worth switching away from rechargeable, although I wish I could silence the warnings.
