Who It's For

This battery is best for homeowners, landscapers, and hobbyist pros who already own Greenworks 80V tools or plan to build a cordless 80V system. It suits people who prioritize longer runtime and consistent power for tasks like mowing a medium to large lawn, because several users reported multi-hour performance when paired with compatible mowers.
