HOCHSTERN 7.5Ah 56V Battery Replacement for EGO Battery BA2800T BA1400T BA4200T BA5600T BA6720T Compatible with EGO 56 Volt Batteries Power Tools 1Pack

What It Is

This is an aftermarket 7.5Ah 56V lithium-ion battery replacement for EGO 56V power tools, designed to power compatible leaf blowers, string trimmers, chainsaws, and mowers that accept EGO’s Arc-Lithium battery platform.

Fitment & Compatibility

• Models it replaces: EGO BA2800T (2.5Ah), BA1400T (4.0Ah), BA4200T (4.0Ah), BA5600T (5.0Ah), BA6720T (7.5Ah).
• Fits all EGO 56V tools with the standard slide-on battery mount (e.g., LB5750, ST1500, LM2100SP).
• Check your tool’s voltage requirement: Must be 56V—this will not work on 40V or 80V EGO tools.
• Physical size: Slightly larger than original 5.0Ah packs; ensure your tool’s battery cavity is deep enough (tighter fit on older mower models).
• Aftermarket note: Not OEM; may lack the battery gauge button that original EGO packs have.

Key Things to Know

• Compatibility with chargers: Works with any EGO 56V charger (CH5500, CH2800, etc.), but charging time may be slightly longer due to higher capacity.
• Installation difficulty: Tool-free—slide on until it clicks; no wiring or modifications needed.
• Performance: 7.5Ah capacity gives longer run time than standard 4.0Ah or 5.0Ah packs (up to 50% more), but weight is heavier (~3.5 lbs).
• Common gotchas: Some users report the battery doesn’t sit perfectly flush on certain tools (e.g., LM2100 mower), causing intermittent power loss. Test fit before full use.
• Warranty: Usually 12-month limited; check seller’s return policy for dead-on-arrival issues.

Should You Buy It

If you own multiple EGO 56V tools and need extra run time without buying a second OEM pack, this is a cost-effective option—but only if you can accept the slightly bulkier fit and lack of an integrated fuel gauge. Best for occasional users who want backup power, not for daily pro use where OEM reliability is critical.
