Battery power formula.

Power P of an electrical device equals voltage V times the current I:

P = V * I

Since energy E is P-times multiplied by time, All We have to do to find the energy stored in a battery is hit both sides of the equation over time.:

E = V * I * T

Hopefully you'll remember that the amp Clock is a measure of the electric charge Q (battery power). Therefore, the final version of the battery power formula looks like this.:

E = V * Q

So ...

The power stored in an E battery is expressed in watt-hours.;

V is battery voltage.;

Q is battery power, measured in amp hours.
