5000mAh High Capacity BA2800 Replacement for EGO 56V Battery Compatible with EGO Battery 5.0Ah Lithium Power Tools Compatible with BA4200 BA4200T BA1400 BA1400T BA2240 Cordless Power Tool(1Pack)

What It Is

This is a 5000mAh (5.0Ah) aftermarket lithium-ion battery pack designed as a direct replacement for the EGO BA2800 and compatible with the EGO 56V power tool system. It’s intended for any EGO 56V cordless lawn mower, string trimmer, blower, hedge trimmer, or chainsaw that accepts the standard Arc-Lithium battery platform.

Fitment & Compatibility

Before buying, verify your tool uses the EGO 56V Arc-Lithium battery interface (the common slide-on, push-button release design). This battery replaces OEM models BA2800, BA4200, BA4200T, BA1400, BA1400T, and BA2240. It will not work with older 40V EGO tools or any non-EGO brand. Check your tool’s model number (e.g., LM2100, LM2101, ST1500, LB6500) to confirm it’s part of the 56V family. No deck size or measurement check is needed—fitment is purely based on the battery mount style. If your tool has a rectangular battery slot with a latch at the top, it’s compatible.

Key Things to Know

• Aftermarket vs OEM: This is not an EGO-branded battery. It may have slightly lower build quality, fewer charge cycles, and no official EGO warranty. Performance can vary between units.
• Installation: Fully drop-in, no tools required. Slide the battery onto the tool until it clicks. Removal uses the same push-button release.
• Charging: Use only an EGO 56V charger (CH5500, CH2800, etc.). Do not mix with third-party chargers—risk of damage or fire.
• Common gotchas: Some users report the battery meter LEDs are less accurate than OEM. Also, aftermarket batteries may not hold a charge as long over time. If your tool has a “low battery” warning that triggers early, this could be the cause.

Should You Buy It

Buy it if you need a spare or backup battery for occasional use and want to save roughly 40–50% over OEM pricing. Skip it if you rely on your mower or trimmer daily for heavy commercial work, need maximum reliability, or expect the same lifespan as a genuine EGO battery—stick with OEM for consistent performance and warranty support.
