A vehicle jack, such as a battery-operated vehicle jack is provided. The jack includes a base, a lift arm, a crank arm, an actuator coupled to the lift arm and an electric motor to actuate the actuator. The lift arm includes a first end that engages a load and a second end that is moveably coupled to the base. The crank arm includes a third end that is pivotally coupled to the base and a fourth end that is pivotally coupled to the lift arm between the first end and the second end. The electric motor actuates the actuator to move the second end of the lift arm relative to the third end of the crank arm to cause a vertical movement at the first end of the lift arm between a lowered position and a raised position.
