�In practice, too much battery discharge current leads to less efficient power output, which non-linearly reduces its operating time with such a current and can lead to overheating./p>

With an off-system unit of ampere-hour, the pendant is associated with the equality: 1 Cl = 1/3600 ampere-hour. 

Pendant  this is the value of the charge that passed through the conductor at a current of 1 A during 1 s. Through the basic SI units, the pendant is expressed by a ratio of the form: 1 Cl = 1 A·s.
