TLDR Review: Greenworks 80V 4.0Ah Battery
Pros
- •Charges in approximately 20 minutes
- •Delivers enough power to mow an entire yard without recharging
- •Compatible with 75+ Greenworks tools including mowers, blowers, weed whackers, and chainsaws
- •Significantly outlasts comparable smalleapacity batteries
- •Covers approximately 0.3 acres per charge for grass trimming
- •Enables uninterrupted work when using backup batteries for swaps
- •LED indicator shows power level during storage
- •Proven durability with reliable performance across multiple seasons
Cons
- •Battery lifespan is disappointingly short
- •Size is too large to fit under snow blower and lawnmower covers
- •4.0Ah weight makes it less ideal for extended weed whacker use
- •Unclear product labeling makes initial battery identification difficult
- •Requires specific storage conditions and periodic charging when not in use for optimal longevity
Bottom Line
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.
