= charge and discharge current of a battery is measured in C-rate. It is defined as the current divided by the thcoretical current under which the batter ald deliver its nominal rated capacity (Ah or mAh) in one hour. For example, a battery rated at 1000 mAh provides 1000 mA for one hour if discharg C rate. The sanme battery discharged at 0.5C provides 500mA for two hours. FEPO4 (with a theoretical capacity of 170 mAh g-') based Li ion battery contains 7.2 g LIFEPO4. Calculate the discharge current (in mA) of the tery at 20 rate.

A “dead” 12-Volt lead/acid storage battery has 5.20 g of PbSO4 (molar mass = 303.3 g), deposited on its electrodes. To recharge it, a “trickle charger” is attached to the Pb anode that supplies 0.180 amperes of current at a voltage of 13.0 V. Calculate how much time it would take to convert all the PbSO4 back into SO42− ions in solution. Enter your answer in hours.
