waitley 56V 5.0Ah Replacement Battery Compatible with EGO 56-Volt Battery BA2800T BA2800 BA4200 BA1400 CS1604 CS1804 Power Cordless Tools(Not Made in EGO)

What It Is

This is an aftermarket 56V 5.0Ah lithium-ion replacement battery for EGO cordless lawn mowers, trimmers, blowers, and other 56V power tools. It’s designed to power medium-duty yard work, like mowing up to a half-acre or running a string trimmer for extended sessions.

Fitment & Compatibility

• Compatible EGO models: BA2800T, BA2800, BA4200, BA1400, CS1604, CS1804, and most EGO 56V tools that accept the ARC-Lithium battery platform.
• What to check: Verify your tool’s voltage requirement (must be 56V) and that the battery slide-in mount matches. This battery uses the same form factor and terminal layout as OEM EGO packs.
• Not made by EGO: It’s a third-party replacement. Does not work with older 40V or 80V EGO tools.
• Physical size: Roughly 6.5 x 4 x 3.5 inches; fits all standard EGO 56V battery bays. No wiring or adapter needed.

Key Things to Know

• Quality variance: Aftermarket cells may have slightly lower runtime and shorter lifespan than genuine EGO batteries. Expect 80–90% of OEM capacity.
• Installation: Snap-in, no tools required. Press firmly until latch clicks. Removal uses the same button as OEM packs.
• Charging: Works with EGO 56V chargers (model CH5500, CH2800, etc.). Do not use with non-EGO chargers.
• Warranty: Typically 1-year limited (check seller). No overcharge protection as robust as OEM—avoid leaving on charger for days.

Should You Buy It

Buy if you need an affordable spare or replacement for light-to-medium EGO 56V yard work and don’t want to pay OEM prices. Skip if you rely on heavy daily commercial use, need maximum runtime, or want the full longevity of an EGO-branded battery.
