How to Measure Battery Capacity

Battery capacity is conventionally measured using units such as ampere-hours (Ah), watt-hours (Wh), or kilowatt hours (kWh), depending on the technology used. Ampere-hours (Ah) measure the total amount of charge that a battery can deliver in one hour. For example, if a battery has a capacity of 10 Ah, it can deliver 10 amps of current for one hour, or 5 amps for
