2Packs 56v 5000mAh Batteries Replacement for EGO 56 Volt Battery Lithium Compatible with EGO 56V Battery BA1400 BA2800 BA2800T BA4200 BA5600T CS1804 CS1604

What It Is

This is a pair of 56-volt, 5000mAh replacement lithium-ion batteries designed to power EGO 56V cordless lawn mowers, string trimmers, blowers, chainsaws, and other tools in the EGO 56V lineup. Each battery delivers 5.0Ah capacity, offering extended runtime for medium to large yards.

Fitment & Compatibility

Before buying, confirm your tool uses the EGO 56V ARC-Lithium battery platform. These batteries are aftermarket replacements for OEM models BA1400, BA2800, BA2800T, BA4200, BA5600T, and compatible with tools like CS1804 (chainsaw) and CS1604 (chainsaw). They will not fit older EGO 24V or 40V tools. Check your tool’s battery port shape—these have the standard EGO slide-on mount. They are not compatible with EGO’s 56V “Power+” or “Peak Power” batteries (e.g., BA5600T is fine, but BA6720T is not). Measure battery compartment depth: these are slightly taller than OEM BA1400 but fit all standard EGO 56V battery slots. Charger compatibility: works with EGO’s 56V rapid charger (CH5500, CH2800) and standard charger (CH2100). Does not charge with EGO’s 56V 4-port charger (CH7000).

Key Things to Know

• Quality: Aftermarket cells may have slightly lower cycle life than OEM EGO batteries. Expect 300-500 charge cycles vs. 500-800 for OEM. They lack the EGO “Arc-Lithium” temperature management, so avoid charging in extreme heat or cold (below 32°F or above 104°F).
• Installation: No tools required—slide the battery onto the tool until it clicks. Ensure the release button is flush. If it doesn’t seat fully, the contacts may not align; clean the tool’s battery terminals with a dry cloth.
• Common gotcha: These batteries are not compatible with EGO’s “Power+” series (e.g., BA6720T, BA8400T). Check your tool’s model number—if it ends in “T” (e.g., BA5600T), these work. If it ends in “P” (e.g., BA6720P), they won’t. Also, they may not fit in some EGO backpack blowers (e.g., LB5750) due to battery compartment depth; measure before buying.

Should You Buy It

Buy this if you already own multiple EGO 56V tools and need a budget-friendly, high-capacity battery pair for daily mowing or trimming. It’s a solid value for users who don’t need OEM warranty or extreme cold-weather performance. Avoid if you rely on EGO’s rapid charging ecosystem (these charge slower on standard chargers) or if your tool requires the “Power+” high-output battery for heavy loads (e.g., dual-battery mowers).
