What is the unit of measure for a battery cycle?

• A. Voltage
• B. Amperes
• C. Amperes-hours
• D. Watt-hours

Answer: (C)

A battery cycle refers to the process of discharging a battery from full to empty and then recharging it back to full. The unit of measure that best describes this process is ampere-hours (often abbreviated as Ah). Ampere-hours quantify the total electric charge transfer over time, specifically indicating how many hours a current of one ampere can be supplied by the battery before it is depleted. When considering battery capacity and cycle performance, ampere-hours provide a clear indication of how much energy a battery can store and deliver. This measure is essential for evaluating battery life and determining whether the battery can meet the energy demands of a specific application. While watt-hours might seem related, as they also measure energy, they incorporate voltage and may not provide a direct assessment focused solely on charge capacity like ampere-hours does. Therefore, ampere-hours is the appropriate unit for measuring a battery cycle's capacity and performance.
