Outdoor equipment batteries and chargers keep cordless blowers, trimmers, mowers, chainsaws, and other lawncare and groundskeeping tools powered up and ready for use. Outdoor equipment batteries supply power to operate equipment. Outdoor equipment battery chargers replenish the power of depleted batteries to allow reuse. Battery backpacks and harnesses hold multiple batteries for more run time. They also shift battery weight away from tools and equipment, making them easier to maneuver and reducing fatigue during extended use.
