Common Questions
Is an ampere-hour a measure of current?
No. An ampere-hour measures electric charge. Current is the rate at which charge moves.
Can ampere-hours be converted directly to watt-hours?
Not without voltage. Watt-hours equal ampere-hours multiplied by voltage for the stated electrical conditions.
Why should Smart Input use the word coulomb instead of C?
The letter C is already used for Celsius. Writing coulomb keeps electrical-charge and temperature requests unambiguous.
Does a higher mAh rating always mean a battery stores more energy?
Not necessarily. Stored energy depends on both charge capacity and voltage, so compare watt-hours when battery voltages differ.
