FirstPower 56V 10.0Ah Battery Replacement for EGO Battery 10Ah BA2800 BA4200 BA5600T 56V Lithium Battery Compatible with EGO 56 Volt Power Tools

What It Is

This is a 56V 10.0Ah lithium-ion battery replacement for EGO’s BA2800, BA4200, and BA5600T power tool batteries. It’s designed to power any EGO 56-volt tool or mower, providing extended runtime for larger yards or heavy-duty tasks.

Fitment & Compatibility

Check before buying:

• Tool model: Works with any EGO 56V tool (mowers, trimmers, blowers, chainsaws, etc.) that accepts the standard slide-on battery pack.
• OEM vs aftermarket: This is a third-party replacement, not made by EGO. It will physically fit but may not be recognized by EGO’s charger or tool if they have firmware checks.
• Measurements: Same dimensions as OEM BA2800/BA4200/BA5600T (approx. 6.5 x 4.5 x 3.5 inches). Verify your battery compartment isn’t too tight for a slightly thicker aftermarket case.
• Charger compatibility: Works with EGO’s standard 56V charger (model CH5500, CH2800, etc.), but some users report slower charging or error codes. Not compatible with rapid chargers.

Key Things to Know

• Installation: Slide on and off exactly like OEM – no tools needed. Ensure the latch clicks firmly.
• Quality: Cells are typically Chinese-made (not Samsung or LG like OEM). Capacity is often slightly less than advertised (expect ~9.0-9.5Ah real-world).
• Gotchas: May not charge fully in EGO’s “rapid” charger; stick to the standard charger. Some users report shorter lifespan (1-2 years vs 3-5 for OEM). Avoid storing below 32°F or above 110°F.
• Warranty: Usually 1 year vs EGO’s 3-5 year warranty. No support from EGO for aftermarket batteries.

Should You Buy It

Buy this if you need a spare or replacement for occasional use and want to save ~40% vs OEM. It’s fine for small yards or light tasks, but for heavy daily use or commercial work, stick with genuine EGO batteries for reliability and warranty.
