## Verdict

This battery charges in a blink (around 20 minutes) and delivers enough juice to mow your entire yard without drama, making it a faithful companion for your Greenworks arsenal of tools. The real bummer? The lifespan doesn't match the hype—reviewers consistently report that the battery loses its spark sooner than expected. If you're serious about keeping your yard work moving without stopping, you'll want to grab a second battery for swaps, because this one won't last an entire season without noticeable performance dips.

**Top pro:** Charges in approximately 20 minutes
**Top con:** Battery lifespan is disappointingly short
