What It Is

This is an aftermarket 56V 5.0Ah lithium-ion battery designed to power EGO 56-volt cordless lawn mowers, trimmers, blowers, chainsaws (e.g., CS1604, CS1804), and other tools in the EGO 56V platform. It replaces OEM models BA2800T, BA2800, BA4200, and BA1400.

Fitment & Compatibility

Voltage & chemistry: Must be 56V lithium-ion – this one is.
OEM models replaced: BA2800T, BA2800, BA4200, BA1400. Check your battery’s label for these numbers.
Tool compatibility: Fits all EGO 56V tools (mowers, trimmers, blowers, chainsaws, etc.) but not EGO 56V backpack or multi-head systems that require a different battery mount.
Physical check: Measure your original battery – this aftermarket unit is roughly 5.5 x 4 x 3 inches and weighs ~2.5 lbs. Ensure your tool’s battery bay matches these dimensions.
Brand note: This is not made by EGO. It’s a third-party replacement. It will not charge on EGO’s rapid charger (CH5500) – use the standard EGO charger (CH2100 or CH2800) or the included aftermarket charger.

Key Things to Know

Quality variance: Aftermarket batteries often use lower-grade cells. Expect slightly shorter runtime and lifespan than OEM (maybe 70–80% of original capacity after 1–2 seasons).
Installation: Zero difficulty – slides into the tool’s battery slot just like OEM. No tools needed.
Charging compatibility: Works with EGO standard chargers (CH2100, CH2800) but not with EGO rapid charger (CH5500). If you own a rapid charger, this battery won’t charge.
Common gotcha: Some users report the battery doesn’t fully seat in older EGO mowers (pre-2018). Check the latch alignment before buying.

Should You Buy It

Buy this if you need a spare battery for light-to-moderate use and want to save ~40% over OEM cost. Skip it if you rely on your EGO tools for heavy commercial work, need the longest runtime, or own a rapid charger – stick with genuine EGO BA2800T/BA4200.
