You are here: Home / Blog / PEVs / How To Test A Battery's Capacity Testing a battery’s capacity is one of the best ways to determine the health of a battery cell. indicator of a battery. To test the capacity of a battery cell, you have to fully charge and fully discharge the cell while precisely measuring the energy in at least one direction.
The easiest and most common way to test a battery’s capacity is to measure its voltage and current under load. Once the battery is fully charged first, a load is placed on the battery and then the voltage and current of the battery is measured. The energy coming out of the battery is counted and added up to form a capacity figure.
Methods for Measuring Battery Capacity The discharge method involves fully discharging the battery under controlled conditions and measuring the total energy delivered. Ensure the battery is fully charged before beginning the test. Use a resistive load, such as a light bulb or resistor, that matches the battery’s rated current draw.
Battery analyzers are specialized devices designed to measure capacity with higher accuracy and provide detailed performance insights. Attach the battery to the analyzer following the provided instructions. Choose appropriate settings based on battery type and desired discharge rate.
When testing a battery, the voltage setting is the most relevant. To test a battery with a multimeter, you'll need the following tools: As a safety precaution, always wear protective goggles and gloves when handling batteries. Additionally, ensure that the workspace is well-ventilated to minimize the risk of exposure to harmful fumes.
Test the capacity of a battery that has a voltage between 1.2 volts and 12 volts. Use the bigger tester below if testing more than 5ah. With this tester, you can check the capacity, voltage, and current of a lithium-ion battery cell.
