Volt Watt Volt Ampere Ampere hour

Correct Answer: Ampere hour

Explanation:

Battery capacity (AH) is defined as a product of the current that is drawn from the battery while the battery is able to supply the load until its voltage is dropped to lower than a certain value for each cell. Capacity of batteries usually expressed in Ampere Hour (AH).
