A battery torque wrench is a battery-operated wrench that can apply a specified torque without effort from the operator. It contains a planetary torque multiplier or a gearbox. A reaction device that absorbs the torque rather than the tool operator. The torque output is adjusted by varying the voltage on the motor. The battery torque wrench is used to remove stubborn nuts, or to apply accurate torque. The gearboxes can have multiplication ratios up to 125:1. By product types, battery torque wrench can be divided into single speed and dual speed

The battery torque wrench is sometimes confused with a standard impact wrench, due to their similar appearance. A battery torque wrench is driven by continuous gearing, and not by the hammers of an impacting wrench. A battery torque wrench has very little vibration, and excellent repeatability and accuracy.

The benefit of a battery torque wrench is its capability to operate independently of an outside power source.

The battery torque wrench market was valued at 321.17 Million US$ in 2018 and is projected to reach 416.81 Million US$ by 2024, at a CAGR of 4.44% during the forecast period.
