56V Lithium-Ion Battery BA2800 Replacement for EGO 56V Battery 5.0Ah, 1-Pack

What It Is

This is a 56V lithium-ion battery with a 5.0Ah capacity, designed to power EGO outdoor power equipment (mowers, trimmers, blowers, chainsaws, etc.) as a direct replacement for the OEM BA2800 battery pack.

Fitment & Compatibility

• Voltage & connector: Must be 56V with the standard EGO slide-on terminal. This fits all EGO 56V tools (Arc-Lithium platform) but not older 56V EGO tools that use the angled “Power+” connector (check your tool’s battery port shape).
• Model numbers: Replaces BA2800, BA2800-T, BA2800-FC. Will also work as a higher-capacity upgrade for BA1400 (2.5Ah) or BA2240 (4.0Ah) tools.
• Physical size: Same footprint as OEM BA2800 – fits all EGO mowers (including 16”, 20”, 21” models) and handheld tools. Does not fit the larger 7.5Ah/10.0Ah “backpack” battery tray on some commercial EGO blowers.
• Tool compatibility: Works with all current EGO 56V tools, but confirm your tool’s release date (pre-2015 models may have connector differences). If your tool has a “Push-to-Release” button on the battery, it’s compatible.

Key Things to Know

• Aftermarket vs OEM: This is a third-party replacement, not made by EGO. It may have slightly lower run time (5.0Ah is nominal) and may not charge in EGO’s rapid charger at full speed.
• Installation: Zero difficulty – slide battery onto tool until it clicks. No tools or wiring needed.
• Common gotcha: Some users report the battery gauge (LED lights) is less accurate than OEM. Let it fully discharge once before first use to calibrate.
• Warranty: Typically 12 months (vs EGO’s 3-year OEM). Check seller’s warranty terms – some offer only 30-day returns.

Should You Buy It

Buy this if you need a spare battery for light-to-moderate use (one mowing or trimming session) and want to save ~30% over OEM. Avoid if you rely on all-day runtime, need fast charging, or want the peace of mind of EGO’s longer warranty. For heavy users, spend extra on the genuine BA2800.
