Upgraded High Capacity 80V 8.0Ah Battery Replacement for Greenworks Pro 80V Battery GBA80200 GBA80250 GBA80300 GBA80400 GBA80500 Compatible with Greenworks 80 Volt Power Tool

What It Is

This is an aftermarket high-capacity 80V 8.0Ah lithium-ion battery replacement for Greenworks Pro 80V cordless lawn mowers, string trimmers, blowers, and chainsaws. It’s designed to extend runtime for larger yards or heavy-duty tasks compared to the standard 4.0Ah or 5.0Ah packs.

Fitment & Compatibility

Before buying, verify your tool is part of the Greenworks 80V family (not 60V or 40V). This battery replaces OEM models GBA80200, GBA80250, GBA80300, GBA80400, and GBA80500. It fits all Greenworks Pro 80V mowers, trimmers, blowers, and chainsaws that use those original packs. Check your tool’s battery port shape—this is a slide-on style, not a push-in. Measure the battery compartment depth if your mower has a low deck; the 8.0Ah pack is slightly taller than the 4.0Ah, so it may not fit under some low-profile mower decks. It is not compatible with Greenworks 60V or 40V tools.

Key Things to Know

• Aftermarket quality varies – This is a third-party replacement, not an OEM Greenworks battery. It may not have the same internal cell quality or BMS protection, so check for UL or CE certification marks.
• Installation is simple – Slide the battery onto the tool’s battery mount until it clicks. No tools required. Ensure the contacts are clean before first use.
• Charging note – Use only with Greenworks 80V chargers (model GCH8020 or similar). Mixing chargers from other voltages can damage the battery or tool.
• Weight – At 8.0Ah, this battery is heavier (approx. 3.5 lbs) than a 4.0Ah pack. This may affect balance on handheld tools like trimmers.

Should You Buy It

Buy this if you need longer runtime for mowing a half-acre or more with a Greenworks 80V mower, or if you want a spare for heavy trimming sessions. Skip it if you have a low-deck mower that won’t fit the taller pack, or if you prefer OEM reliability and warranty support over price savings.
