how many volts in a d cell battery
Report Abuse. D batteries, like AA, C, AAA all supply 1.5 volts more or less. There aren't any volts 'in' any battery, since volts are not a measure of a quantity of electricity, bur rather of the electromotive potential of the energy in the battery.
What's 'in' a battery is energy, which is watt hours (there are other units). A battery's volts x amps x time gives the energy in a battery. A good alkaline D cell can supply more that 1 ampere hour at 1.5 volts or or 1.5 watt-hours of energy. Source(s): physicist/ electrical engineer. squeezie_1999 Â· 5 years ago.
