82 V 4000 mAh lithium-ion replacement pack

This 82-volt battery delivers 4000 mAh capacity for Greenworks outdoor tools such as the G82B25, GL500 and GL600 series. It fits 16-inch brushless string trimmers, hedge trimmers, brush cutters and compatible push mowers. The pack uses lithium-ion chemistry and a fully decoded chip that communicates with the original tool electronics. It is a direct replacement for the original equipment battery.

Steady output during extended cutting sessions

The 328 Wh energy rating supports prolonged run time on hedge trimmers, brush cutters and mowers without the voltage sag seen in lower-capacity packs. Lithium-ion cells maintain consistent power through dense foliage or thick grass rather than fading after a short burst. The integrated chip manages cell balancing during discharge, protecting the pack during heavy, continuous use. Users report reliable performance across multiple charge cycles.

Rugged housing with original-style connector

The casing measures 215.60 by 118.80 by 84.00 mm and weighs 2380 g, matching the form factor of the Greenworks original so it locks into the tool without modification. A precision-moulded connector ensures secure contact even when the tool vibrates during operation. The pack carries ISO 9001, RoHS and CE certifications, confirming compliance with safety and environmental standards. Simple drop-in installation lets you resume work quickly.
