1 Pack 5000mAh Ultra High Capacity Lithium ion Battery Replacement for EGO 56V Battery Compatible with EGO 56 Volt BA2800 BA2800T BA4200 BA4200T BA1400 BA1400T BA5600T Cordless Power Tools(Green)

What It Is

This is a 5000mAh lithium-ion battery replacement for EGO 56V cordless lawn mowers, trimmers, blowers, and other outdoor power tools. It’s designed to power EGO equipment that uses the standard 56V arc-lithium platform.

Fitment & Compatibility

• Fits EGO 56V models: BA2800, BA2800T, BA4200, BA4200T, BA1400, BA1400T, BA5600T batteries.
• Check your tool’s voltage: Only for 56V EGO tools—not compatible with 40V or 80V EGO systems.
• Physical size: Same footprint as OEM BA2800/BA4200 packs. Measure your battery compartment: ~6.5 x 4 x 3 inches (16.5 x 10 x 7.5 cm).
• Aftermarket: This is a third-party replacement, not EGO OEM. It may not have the same internal BMS (battery management system) or charge profile as genuine packs.
• Charger compatibility: Works with EGO standard 56V chargers (CH5500, CH2100, etc.), but charging times may vary. Avoid using with rapid chargers unless verified.

Key Things to Know

• Capacity vs. OEM: 5000mAh is higher than the standard BA2800 (2800mAh) and matches the BA4200 (4200mAh). Expect longer runtime—up to 60-90 minutes on a mower, depending on load.
• Installation: Snap-in fit, no tools required. Ensure the battery clicks fully into the tool’s base; a loose connection can cause intermittent power.
• Quality note: Some users report slightly shorter lifespan than OEM. The cells are generic; heat management may be less robust. Avoid leaving on charger for days.
• Common gotcha: If your tool has a fuel gauge, it may not read accurately with this pack—some users see blinking or incorrect bars.

Should You Buy It

This is a solid budget option if you need extra runtime for an older EGO tool and don’t want to pay OEM prices. It’s best for light-to-medium duty use (trimming, blowing, or mowing a small lawn). Avoid if you rely on precise fuel gauge readings or need maximum durability for heavy commercial use—stick with OEM for reliability.
