The solar charger will keep 30 day of battery voltage history. It is hard to tell what has exactly happened to a battery during its lifetime. It is not recommended to mix batteries of different ages in one battery bank. In case of multiple battery system replace the whole battery bank. When the faulty battery is charged, the damaged cell will not accept charge and the remaining cells will receive the broken cell’s charge voltage and thus will be overcharged. When a battery is old or has been damaged, a likely scenario is that one of these cells is not operational anymore. Err 203, Err 205, Err 212, Err 215 - Internal supply voltage errorĪ battery that is at the end of its service life or has been damaged by incorrect use, can be prone to being overcharged.Ī battery contains a number of cells that are connected in series.
