Battery capacity is measured in ampere-hours (Ah) or milliampere-hours (mAh). Battery capacity indicates the amount of electric charge a battery can store. Ampere-hours represent the flow of current over time. For example, a battery rated at 1 Ah can deliver 1 ampere of current for one hour.
1. Understanding Battery Capacity Battery capacity is quantified in ampere-hours (Ah) or milliampere-hours (mAh). It represents the total amount of charge a battery can store and deliver at a specific voltage. A higher capacity indicates a longer duration for which the battery can power devices before needing a recharge.
The unit commonly used to measure battery capacity is the ampere-hour (Ah) or its subunit i.e., milliampere-hour (mAh). Other than these two units higher capacity batteries are measured in watt hour or kilowatt hour. Ampere-hour (Ah): This unit of battery capacity represents how much current battery can provide for 1 hour.
For example, a battery with a capacity of 2 Ah, can provide a 2-ampere current for 1 hour before it needs charging again. Similarly, we can define other units as well. The formula for calculating battery storage capacity is given below: Battery Capacity = Current (in Amperes) × Time (in hours)
Battery capacity testers: Devices that can perform controlled discharge tests, directly measuring capacity in ampere-hours (Ah). Electrochemical impedance spectroscopy (EIS) analyzers: Devices that measure battery impedance to estimate capacity.
Battery Capacity (Ah)=800mA x 2h = 1600Ah. If the battery rating is only indicated in amp-hours, you can change it to watt-hours using this method: Watt-hour (Wh) = Ampere-hour (Ah) × Voltage (V). Assuming a 1600Ah battery has 12V, the total watt-hours of the battery is 19.2kWh.
