Battery capacity is given in mAh (milli-ampere hour). 1 mAh = 3.6 coulombs
For example, AA batteries are provided with capacities 600 mAh, 800 mAh, 1000 mAh etc.
Given the voltage and capacity of the battery, the total energy supplied by it can then be calculated.
For example, for a battery of 1.5 volts and capacity 1000 mAh (=3600 coulombs), the total energy stored in the battery = 3600 x 1.5 J = 5400 J
