Are primary batteries fully replaceable by rechargeable batteries even though they are 1.2 volts?
Yes, NiMH batteries are ideal substitutes in most cases, especially in high power consumption electronic devices. Although alkaline batteries are rated at a nominal voltage of 1.5 volts, as they begin discharging, their voltage continuously drops. Over the course of discharge, the average voltage of alkaline batteries is in fact about 1.2 volts, very close to NiMH batteries. The main difference is that an alkaline battery starts at 1.5 volts and gradually drops to less than 1.0 volt, while NiMH batteries stay at about 1.2 volts for most of the service time.
