The purpose of the capacity, or load bank test is to determine the true capacity of the battery by finding the time that it takes the battery to reach the end of discharge voltage and compare it to the expected time from the battery manufacturer’s published ratings. The ratio between the resulting time and the expected time, with
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.
By measuring the discharge time and combining the current value, the battery capacity can be accurately calculated. This method is relatively simple to operate and the results are relatively reliable, but it requires certain experimental equipment and technical support. 3. Pulse discharge method: a fast and accurate modern technology
The ratio between the resulting time and the expected time, with a temperature correction, defines the capacity of the battery in percentage. This method is the Time Adjusted capacity test and is the preferred method for tests longer than one hour.
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.
Before determining a diagnostic from a battery capacity result and judging it only by the percentage, it is important to confirm the average cell temperature at the beginning, and if a correction factor was used or is required, then it needs to be compared to previous results.
