56V 5.0Ah Lithium-Ion Battery Replacement for EGO 56 Volt Battery BA2800 BA2800T BA2242T BA2240 BA1400T BA4200 BA4200T BA5600T, for EGO 56V Power+ Tools ST1623T ST1511T LB7654 LB6151 CS1804 CS1604

What It Is

This is a 56V 5.0Ah lithium-ion replacement battery for EGO Power+ lawn mowers, trimmers, blowers, chainsaws, and other 56V tools. It powers cordless outdoor equipment where the original battery has worn out or you need a spare for longer runtime.

Fitment & Compatibility

Check that your tool uses the EGO 56V Power+ platform (not the older 56V ARC or 56V commercial line). This battery replaces OEM models BA2800, BA2800T, BA2242T, BA2240, BA1400T, BA4200, BA4200T, and BA5600T. It fits tools like the ST1623T trimmer, ST1511T trimmer, LB7654 blower, LB6151 blower, CS1804 chainsaw, and CS1604 chainsaw. Not compatible with EGO’s 56V Nexus or 56V CS1800 models without verifying the battery slot shape. Measure your battery compartment: this battery is roughly 5.5 x 3.5 x 6 inches. If your original battery has a different latch design or terminal layout, it won’t work.

Key Things to Know

• Quality: Aftermarket, not OEM. Some users report slightly shorter runtime than genuine EGO batteries, but it’s generally reliable for light-to-medium use.
• Installation: No installation—just slide into the tool until it clicks. Ensure the battery is fully seated; loose fit can cause intermittent power.
• Gotcha: This battery may not charge in EGO’s rapid charger (CH5500) if the charger detects non-OEM cells. Use the standard EGO charger (CH2100 or CH2800) to avoid issues.
• Gotcha: The 5.0Ah capacity gives about 30-45 minutes of mowing on a 21-inch mower, less for heavy trimming. Consider your runtime needs before buying.

Should You Buy It

Buy this if you need a budget-friendly spare for occasional use on EGO 56V tools and you’re okay with slightly less runtime than OEM. Skip it if you rely on your mower for large lawns daily or need guaranteed compatibility with rapid chargers—stick with a genuine EGO battery.
