Replacement for Greenworks 80V Battery 3500mAh, Compatible with Greenworks Pro 80V 75+ Power Tool, Replace for 80 Volt Greenworks Battery GBA80200 GBA80250 GBA80400 GBA80500 GCH8040 2502202

What It Is

This is a 3500mAh replacement battery for Greenworks 80V cordless outdoor power tools, designed to power mowers, trimmers, blowers, and chainsaws in the Greenworks Pro 80V line. It serves as a direct drop-in replacement for depleted or failed OEM batteries, restoring runtime and performance.

Fitment & Compatibility

• Voltage & Chemistry: Must be 80V (nominal) lithium-ion – this battery is, so it matches all Greenworks 80V tools and chargers.
• OEM Models Replaced: Compatible with Greenworks GBA80200 (2.0Ah), GBA80250 (2.5Ah), GBA80400 (4.0Ah), GBA80500 (5.0Ah), and GCH8040. Also fits 2502202.
• Physical Fit: Same footprint and slide-lock design as OEM 80V batteries – no adapter needed. Check that your tool’s battery compartment is not physically damaged or warped.
• Charger Compatibility: Works with any Greenworks 80V charger (model numbers like GCH8040 or 2997502). Do not use on 40V or 60V chargers.
• What to Measure: Not deck size – just ensure your tool is from the Greenworks Pro 80V family (not 60V or 40V). If your original battery has a part number starting with GBA80, this will fit.

Key Things to Know

• Not OEM: This is an aftermarket replacement, not a genuine Greenworks part. It may have slightly lower cycle life or capacity consistency than OEM, but user reviews (4.6/5) indicate reliable performance for the price.
• Installation Difficulty: Zero – slide the battery onto the tool until it clicks. No tools or wiring required.
• Charge Time: Expect 60–90 minutes on a standard Greenworks 80V charger. It will not charge faster on a rapid charger due to internal BMS limits.
• Common Gotcha: If your tool runs but cuts out quickly, the battery may be in thermal protection. Let it cool before recharging. Also, never store fully discharged – recharge to 50% for winter storage.

Should You Buy It

Buy this if you need an affordable spare or replacement for your Greenworks 80V tools and don’t mind an aftermarket battery with solid reviews. It’s a good value for light-to-moderate use (e.g., one lawn mowing session per charge). Avoid if you require maximum runtime or warranty support from Greenworks – stick with OEM for heavy-duty or commercial use.
