Which unit designates the storage capacity of a battery?

• A. A Kilowatt-hour
• B. An amp-hour
• C. A standard operating condition
• D. A maximum point power

Answer: (B)

Amp-hours quantify how much electric charge a battery can store, which is its storage capacity. It represents the current a battery can deliver over a period of time, so a rating of 50 Ah means it could supply 1 A for 50 hours, or 5 A for about 10 hours (under ideal conditions). Kilowatt-hours describe energy stored, which combines voltage and Amp-hours, and is used when talking about total energy or running time of a device at a given voltage. The other terms aren’t about how much charge is stored: standard operating condition is a testing reference, and maximum point power refers to instantaneous power output. So Amp-hours is the unit that designates the battery’s storage capacity.
