80V 3.0Ah Replacement for Greenworks Battery, Upgraded Battery Compatible with Greenworks 80V Power Tools and Chargers

What It Is

This is a 3.0Ah lithium-ion battery replacement for the Greenworks 80V platform, designed to power cordless lawn mowers, string trimmers, chainsaws, blowers, and other 80V tools. It’s a higher-capacity upgrade over the standard 2.0Ah pack, offering longer runtime for medium-sized yards (up to 1/3 acre).

Fitment & Compatibility

• Brand fit: Works with all Greenworks 80V tools and chargers (including G-Max and Pro models).
• Check before buying: Verify your tool or charger is marked “80V” (not 40V or 60V). The battery shape and terminal layout are identical to OEM Greenworks 80V packs, so it fits any tool that accepts the standard slide-in design.
• What to measure: Not needed—this is a direct drop-in replacement. No deck size or adapter required.
• OEM vs aftermarket: This is an aftermarket battery, not Greenworks branded. It will charge on Greenworks 80V chargers but may not trigger the charger’s full charge cycle (see below).

Key Things to Know

• Quality: Uses generic cells; runtime is close to OEM 2.5Ah but may degrade faster after 100+ cycles. Not recommended for heavy daily commercial use.
• Installation: Trivial—slide into tool or charger until latch clicks. No tools needed.
• Gotcha: Some users report the battery doesn’t fully charge on older Greenworks 80V chargers (stops at 80-90%). If you have a pre-2020 charger, test the first charge cycle.
• Weight: Heavier than 2.0Ah (about 1.2 lbs more), but balances fine on handheld tools.

Should You Buy It

Buy this if you need a budget-friendly backup or upgrade for light to medium residential use (mowing, trimming, leaf blowing) and already own a Greenworks 80V system. Skip it if you need maximum lifespan or reliable all-day runtime for a large lawn—stick with OEM or a higher-capacity (4.0Ah+) pack.
