To control the lead storage batteries it is necessary to consider the characteristics of each battery connected in series. In this study, the charging and discharging characteristics of sealed lead storage batteries 12V/1.2A was investigated one by one through experiments. The results of the experiment shows that one should consider the state of each battery to prevent overcharge or deep discharge. Also, we designed an equipment to measure battery voltages simultaneously using micro-controller. This equipment will be useful for monitoring batteries at PV generation system.
