Reoben BA2800T 56V Lithium Battery Replacement for EGO Battery 56 Volt 5.0Ah

What It Is

This is a 56V 5.0Ah lithium-ion aftermarket battery designed to replace the original EGO battery in any EGO 56V cordless lawn mower, trimmer, blower, or other outdoor power tool that uses the ARC Lithium platform.

Fitment & Compatibility

• Check your tool’s voltage: Only works with EGO 56V tools – not compatible with 40V, 80V, or other brands.
• Physical fit: BA2800T is slightly taller than some EGO original batteries (e.g., BA1400, BA2800). Measure your battery compartment depth – if your mower or tool has a tight battery cavity, it may not seat fully.
• OEM vs aftermarket: This is a third-party replacement, not made by EGO. It will not charge on EGO’s standard charger – you must use the included charger or a compatible aftermarket 56V charger.
• Model numbers: Fits EGO models that originally used BA1400, BA2800, BA4200, BA5600, or BA6720 batteries. Confirm your tool’s model number (e.g., LM2100, LM2101, LB5300, ST1500) supports a 5.0Ah battery.

Key Things to Know

• No OEM compatibility with EGO charger: The battery uses a different charging protocol – you must use the charger that comes with it, not your existing EGO charger.
• Performance: 5.0Ah capacity is comparable to EGO’s BA2800 (2.5Ah) in runtime but may deliver slightly less power under heavy load (e.g., thick grass) due to lower discharge rate.
• Installation: Simple drop-in – no tools required. Ensure battery slides fully into the tool’s slot and latches securely.
• Longevity: Aftermarket batteries often have shorter lifespan than OEM. Expect 1–2 seasons of regular use before capacity noticeably degrades.

Should You Buy It

Buy this if you need a budget spare battery for light to moderate yard work and don’t mind giving up compatibility with your EGO charger. It’s a decent value for occasional trimming or mowing small lawns, but serious users or those with heavy-duty EGO tools should stick with OEM for reliability and full performance.
