80V 3.5Ah Battery Replacement for Greenworks 80V Battery, Fit for Greenworks Pro 80V Battery GBA80200 GBA80250 GBA80400 GBA80500 GCH8040 2502202 GST80320 BL80L00 ED80L00

What It Is

This is a replacement 80V 3.5Ah lithium-ion battery for Greenworks cordless lawn mowers, string trimmers, blowers, and other 80V outdoor power tools. It’s designed for medium-duty yard work—enough runtime for a typical 1/4-acre lawn on a single charge with a mower, or about 30-45 minutes of trimming.

Fitment & Compatibility

Check before buying:

• Model compatibility: Fits Greenworks Pro 80V batteries GBA80200 (2.0Ah), GBA80250 (2.5Ah), GBA80400 (4.0Ah), GBA80500 (5.0Ah), and tools GCH8040, 2502202, GST80320, BL80L00, ED80L00. Also works with any Greenworks 80V tool that accepts the standard slide-in battery (most 80V line from 2015 onward).
• Physical fit: Same footprint as OEM 80V batteries—measures roughly 6.5" x 4" x 3". Fits all Greenworks 80V mowers, trimmers, blowers, and chainsaws with the rear-mount or top-mount battery slot. Does not fit 60V or 40V tools.
• OEM vs aftermarket: This is a genuine Greenworks OEM battery, not a third-party replacement. Use with Greenworks charger only (80V charger sold separately).
• Voltage warning: Only for 80V tools. Do not use on 40V or 60V Greenworks equipment—different connector and voltage.

Key Things to Know

• Runtime: 3.5Ah provides roughly 35–45 minutes of mowing on a 20" deck (depending on grass thickness). Expect less in tall/wet grass or with blower on high speed.
• Installation difficulty: Trivial—slide battery into tool until it clicks. No tools needed. Charging takes about 60–90 minutes with the Greenworks 80V rapid charger.
• Common gotchas: Battery has a built-in charge indicator (push button on top). If it doesn’t charge, check charger compatibility (must be Greenworks 80V charger, part # 2901302 or similar). Avoid fully draining—store at 40–80% charge for longest life.
• Warranty: Greenworks offers 2-year warranty on this battery. Keep receipt for claims.

Should You Buy It

Buy this if you already own a Greenworks 80V tool and need a spare or replacement battery for medium-duty yard work. It’s a solid OEM option—reliable, good runtime for the price, and fully compatible with your existing charger and tools. Skip if you need more runtime (go with the 5.0Ah GBA80500) or if your tool is a different voltage.
