A hybrid battery-charging device with input terminals for connecting a current source, first battery connections for connecting a lead-acid battery and second battery connections for connecting a high-cycle chemical battery. A two-way DC/DC converter with first and second sets of terminals is connected with the second battery connections, and with the first battery connections. A charge and discharge control system of the charging device is operative to detect when an internal resistance of the lead-acid battery exceeds a predetermined resistance threshold, and to control the DC/DC converter, in response to the internal resistance of the lead-acid battery exceeding the predetermined resistance threshold, such that, in a discharge mode, the lead-acid battery and the high-cycle chemical battery are discharged in parallel during a parallel discharge phase. |
