A method of testing a battery pack, wherein a load is connected to a charger and the battery pack, and receives power supply from either the external charger or the battery pack. When the external power line is normally supplied to the load through the charger, the battery pack is purposely enabled to start its discharge and to supply power to the load. When the output voltage of the battery pack drops below a threshold level or the discharging time exceeds a preset limit, the charger re-supplies its output voltage to the load and to charge the battery pack. By the purposeful charge/discharge operations, characteristic data of the battery pack are collected and recorded for estimation of the battery pack capacity and the remaining service life.
