Charging, care, and compatibility

This Lithium-Ion battery delivers fade-free performance and can be charged at convenient times without memory effects. A typical charge supports finishing a task before needing a top-up, and the USB port expands charging options beyond a traditional stand-alone charger. The battery is part of the Greenworks G-MAX 40V system and is intended for use with compatible G-MAX 40V tools and the BAF704 charger (29482). Note that it is not compatible with older 40V Greenworks tools outside the current G-MAX platform.
