For professional maintenance personnel, the capacity tester is the preferred tool for measuring battery capacity. By simulating the actual charging and discharging process of the battery, the capacity tester can accurately measure the capacity information of the battery.
By measuring the voltage across the battery, its remaining capacity can be preliminarily estimated. The constant current discharge method is a more accurate battery capacity test method. Connect the battery to a certain load and discharge it at a constant current until the battery voltage drops to the predetermined cut-off voltage.
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh.
The formula for determining the capacity of a lead-acid battery is: For example, if a lead-acid battery has a reserve capacity of 120 minutes, its capacity would be: It is important to note that the capacity of a lead-acid battery decreases as the temperature drops. At 32°F, the capacity is only about 60% of its rated 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.
To estimate battery capacity using a multimeter, follow these steps: Measure the OCV using the multimeter’s voltage setting. Compare the measured voltage with the manufacturer’s voltage vs. state of charge (SOC) chart. Estimate the battery capacity by multiplying the rated capacity by the SOC percentage obtained from the chart.
