How do Alkaline batteries compare to rechargeable batteries?
A. Alkaline batteries can not deliver their full capacity for long periods. Alkaline batteries may be rated at a higher capacity than rechargeable batteries, but they will only provide their full power if the power drain is slow. Rechargeable NiMH batteries can last 3-4 times longer than Alkaline batteries in digital cameras and other high drain electronic devices and are the preferred option.
