It doesn''t provide an individual cell level report. Similarly, just measuring the float voltage across a battery set doesn''t provide a true indication of its condition. The best way to assess the true state of a large battery set is through external battery testing. For large battery sets, individual block testing can be more reliable.
Battery Charging and Discharging Parameters
However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. 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 ...
