2 Packs 56 Volt Lithium ion Battery BA2800T Replacement for EGO 56V Battery 5000mAh(Green)

What It Is

This is an aftermarket 56V lithium-ion battery pack (BA2800T replacement, 5,000mAh) designed to power EGO lawn mowers, string trimmers, blowers, and other 56V EGO outdoor power tools. It’s a drop-in alternative to the OEM EGO BA2800, intended for users needing a spare or replacement battery.

Fitment & Compatibility

• Voltage & Chemistry: Must match EGO’s 56V system. This battery is 56V, 5,000mAh (equivalent to 2.5Ah).
• OEM Part Cross-Reference: Replaces EGO BA2800 (and BA2800T). Not compatible with older EGO 56V batteries like the BA1400 or BA4200 without verifying connector shape.
• Physical Check: Measure your OEM battery dimensions (approx. 5.5” x 3.5” x 4.5”). This battery is nearly identical, but confirm your mower’s battery tray depth—some EGO models have tight clearance.
• Tools: Fits all EGO 56V tools that accept the BA2800 form factor (common on newer models). Avoid if your tool uses a slide-on or side-mount design (e.g., older EGO chain saws).
• Warranty Note: Aftermarket—no EGO warranty. Check seller’s return policy.

Key Things to Know

• Quality & Performance: Rated 5.0/5 (26 reviews), but aftermarket cells may degrade faster than OEM. Expect similar runtime to an OEM BA2800 (about 30-45 min on a push mower).
• Installation: Trivial—slide into battery port until it clicks. No tools required. Ensure contacts are clean.
• Gotchas: Does not include a charger (use your EGO 56V charger). Some users report slightly heavier weight than OEM. Not compatible with EGO’s “Power+” or “Arc” series batteries (different voltage/connector).
• Safety: Aftermarket batteries may lack overcharge/overdischarge protection. Use only with EGO chargers to avoid fire risk.

Should You Buy It

Buy if you need a budget-friendly spare for an EGO 56V tool that accepts BA2800-style batteries and you’re comfortable with aftermarket risk (no OEM warranty, potential shorter lifespan). Skip if you want guaranteed longevity, full safety certifications, or have an older EGO model with different battery tray dimensions.
