Battery-driven torque wrenches use high-capacity, rechargeable lithium-ion (Li-ion) batteries—typically 18V, 36V, or 48V—to provide cordless, high-torque performance, often featuring fast charging and brushless motor compatibility for maximum mobility and precision. These tools are designed for portability and sustained power in industrial, construction, and automotive applications, with battery capacities often ranging from 2.0Ah up to 6.0Ah or higher for extended runtime
