Greenworks 40V 2.0Ah Lithium-Ion Battery (Genuine Greenworks Battery / 75+ Compatible Tools)

What It Is

This is a genuine Greenworks 40V 2.0Ah lithium-ion battery, designed to power Greenworks 40V cordless lawn mowers, string trimmers, blowers, chainsaws, hedge trimmers, and over 75 other 40V tools. It provides runtime for small-to-medium yards (up to 1/4 acre) and is not for 60V or 80V systems.

Fitment & Compatibility

Before buying, confirm your tool uses the Greenworks 40V platform (look for “40V” on the battery port or tool label). This battery fits all Greenworks 40V tools with the standard slide-in port—including push mowers, self-propelled mowers (e.g., model 25302, 25312), and handheld tools (e.g., 20672 trimmer, 21332 blower). It does not fit 60V or 80V tools, nor older Greenworks 24V or 48V systems. Measure the battery compartment: dimensions are 5.1 x 3.5 x 2.6 inches. Avoid third-party “compatible” batteries—they often lack overcharge protection or proper fit. Check your tool’s model number in the manual or under the battery port.

Key Things to Know

• Quality: Genuine Greenworks battery includes overcharge, over-discharge, and temperature protection. Third-party knockoffs may swell or fail early.
• Installation: Slide in until it clicks—no tools needed. Ensure the latch is fully engaged before use.
• Gotcha: 2.0Ah provides ~30-45 min runtime on a mower (1/4 acre). For larger yards, consider the 4.0Ah or 5.0Ah battery (sold separately). This battery is not compatible with older Greenworks 40V chargers (pre-2018)—check charger model number.
• Storage: Store at 40–80°F. Extreme cold reduces runtime; extreme heat can damage cells.

Should You Buy It

Buy this if you already own a Greenworks 40V tool and need a spare or replacement battery for light-to-moderate yard work. It’s reliable, safe, and backed by Greenworks warranty. Skip it if you have a larger yard (over 1/4 acre) or want longer runtime—step up to the 4.0Ah or 5.0Ah battery instead.
