2 Pack 10000mAh Ultra High Capacity Lithium ion Battery Replacement for EGO 56V Battery Compatible with EGO 56 Volt BA2800 BA2800T BA4200 BA4200T BA1400 BA1400T BA5600T Cordless Power Tools(Green)

What It Is

This is a 2-pack of 10000mAh lithium-ion replacement batteries for EGO 56V cordless lawn mowers, trimmers, blowers, and other outdoor power tools. They are aftermarket alternatives to OEM EGO batteries like the BA2800, BA4200, and BA1400 series.

Fitment & Compatibility

• Voltage & chemistry: Must be 56V lithium-ion (EGO’s standard). These are, so they fit all EGO 56V tools.
• OEM model numbers: Compatible with BA2800, BA2800T, BA4200, BA4200T, BA1400, BA1400T, BA5600T. Check your tool’s manual or battery label for these numbers.
• Physical fit: Measure your original battery’s dimensions and terminal layout. These are aftermarket—some users report slightly looser fit in the tool’s battery slot. Verify the battery slides in and clicks without forcing.
• Not for: EGO 56V tools with the older “arc” shape battery (pre-2015). These are for the rectangular “flat-top” style. If your battery has a curved top, these won’t work.

Key Things to Know

• Capacity: 10000mAh (10Ah) is ultra-high. Expect longer runtime than OEM BA2800 (2.5Ah) or BA4200 (4.0Ah). Great for large lawns or heavy use.
• Installation: Drop-in replacement. No tools or modifications needed. Just slide in and lock.
• Common gotchas: Aftermarket batteries may not communicate battery level accurately with EGO tool displays. Some users report the tool’s fuel gauge showing wrong percentage or blinking. Also, warranty is from the seller, not EGO—check return policy.
• Quality variance: These are not OEM. Build quality and cell consistency vary. Some packs fail early; others perform well. Read recent reviews for your specific seller.

Should You Buy It

Buy if you need high runtime at a lower price than OEM, and you’re comfortable with aftermarket risk (possible fit looseness, no EGO warranty, inaccurate gauge). Skip if you want guaranteed compatibility, precise battery info, and long-term reliability—stick with genuine EGO batteries.
