    What is a battery discharge test?

    The battery discharge test is perhaps one of the most reliable tests you can perform on a battery or a battery bank. It provides a comprehensive insight into the health status of the cells. In this post, we will analyze this test applied to stationary battery technology, with a focus on battery banks. Let's get started!

    How a battery discharge process is performed in safe conditions?

    For the discharge process to be performed in safe conditions, besides gathering information about the battery's capacity, SoC and SoH at the beginning of the process it is necessary to monitor the temperature and voltage of individual modules, preferably even groups of cells, as well as to control the discharge current.

    What happens when a battery is discharged deep?

    When a battery undergoes deep discharge, several critical changes occur: Voltage Drop: As the battery discharges, its voltage decreases. Each battery type has a specific cut-off voltage where it ceases to function effectively. For example, lead-acid batteries typically should be discharged at 10.5 volts.
