This Drive Bariatric Patient Lift features a removable battery to enable you to continuously use this lift even when an outlet is not within reach. The battery charges using a regular AC outlet. The battery is removable and can be charged when outside of the patient lift. This enables you to charge a depleted battery while still using a charged battery to continue repositioning patients. To do this, however, you would need an additonial rechargeable battery. This lift will sound a warning when the battery power falls below 50% to give you ample time to make the necessary adjustments. Also, this lift's base is adjustable to make storage in the bedroom much easier. Plus, to make positioning patients easier, this cradle has 4 points to attach the sling and has 360 degree rotation. Features four dual 3" heavy duty front casters. Included with this patient lift is an external charger and wall mounted bracket to let you charge a depleted battery while outside of the patient lift. Weight capacity: 600 lbs.
