The nominal capacity of sealed lead acid battery is calculated according to JIS C8702-1 Standard with using 20-hour discharge rate. For example, the capacity of WP5-12 battery is 5Ah, which means that when the battery is discharged with C20 rate, i.e., 0.25 amperes, the discharge time will be 20 hours.
1. Objective Methods other than capacity tests are increasingly used to assess the state of charge or capacity of stationary lead-acid batteries. Such methods are based on one of the following methods: impedance (AC resistance), admittance (AC conductance).
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.
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.
As the capacity of lead acid battery decreased or the battery is aged, its internal resistance will be increased. Therefore, the internal resistance data may be used to evaluate the battery’s condition. There are several internal resistance measurement methods, and their obtained values are sometimes different each other.
Batteries delivering above 80% are generally still in good condition, though they should be monitored for any decline. Capacity testing is one of the most reliable methods for evaluating the true health of a lead-acid battery. However, it can be time-consuming, as the battery must be fully discharged and then recharged. 3.
