Abstract
An electric power tool that receives driving power from a rechargeable battery includes loads and a control circuit that controls supply of the driving power from the rechargeable battery to the loads. The control circuit sets and stores for each of the loads a reference voltage value of the rechargeable battery used for stopping or issuing a notification in order to obviate over-discharging of the rechargeable battery.
