Lead-acid batteries are highly sensitive to temperature. Testing should ideally be conducted at room temperature to ensure accurate results. Extremely high or low temperatures can skew the results of voltage, capacity, and resistance tests. To ensure optimal performance, it is recommended to perform battery testing at regular intervals.
Here, we describe the application of Incremental Capacity Analysis and Differential Voltage techniques, which are used frequently in the field of lithium-ion batteries, to lead-acid battery chemistries for the first time.
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.
The standard procedure for conducting a battery capacity test involves charging the battery to its full capacity, then discharging it completely while measuring the amount of energy it produces. The test should be conducted under controlled conditions, with the battery at a specific temperature and discharge rate.
