。[Claims for Utility Model Registration] It is equipped with a battery and an electric pump driven by the battery, and by operating an operating means, power from the battery is supplied to the electric pump to drive the electric pump. The battery-driven work machine is configured to perform related operations of the work machine even when the pressure generated is a battery-driven work machine, which is provided with a battery voltage detection device that detects when the battery voltage becomes lower than a predetermined voltage value, and the battery voltage detection device In a battery-driven work machine equipped with an electric pump drive stop means that stops driving the electric pump when the device detects that the battery voltage has fallen below a predetermined voltage value, the battery voltage detection device is once activated. A battery-driven working machine characterized by comprising a holding means that continues to stop driving the electric pump until a predetermined release is performed when the driving of the electric pump is stopped.
