In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. For example, a battery capacity of 500 Ah that is theoretically discharged to its cut-off voltage in 20 hours will have a discharge rate of 500 Ah/20 h = 25 A. Furthermore, if the battery is a 12V ...

How to discharge energy storage lead-acid battery?
Step 1: Check the Battery Voltage. Before discharging the battery, it is essential to check its voltage to ensure that it is fully charged. You can use a multimeter to measure the voltage of the battery. A fully charged 12-volt lead-acid battery should read around 12.6 volts. If the voltage is lower than this, you need to charge the battery first.
