BA2800 12.0Ah Replacement for EGO Battery Compatible with EGO Battery 56V 12.0 Ah BA2800T BA4200T BA5600T BA1400(12.0Amps-1P)

What It Is

This is a high-capacity 56V 12.0Ah lithium-ion battery replacement for EGO lawn mowers, string trimmers, blowers, and other 56V Arc-Lithium tools. It’s designed for long runtime on large lawns or heavy-duty jobs without needing a mid-task recharge.

Fitment & Compatibility

• Brand compatibility: Works with all EGO 56V Arc-Lithium tools and chargers. It replaces OEM models BA2800, BA2800T, BA4200T, BA5600T, and BA1400 (12.0Ah versions).
• Physical fit: Identical size and slide-lock mechanism to OEM 12.0Ah packs. Fits all EGO mowers, but verify your mower’s battery compartment depth (some older mowers may have a tight fit with taller packs).
• What to check: Ensure your charger is compatible (EGO standard 56V charger works). If you have a rapid charger, confirm it can handle 12.0Ah capacity (most do). Do not use with non-EGO 56V tools.
• Measurement: ~7.5 x 5.5 x 4.5 inches, 5.5 lbs.

Key Things to Know

• Quality: Aftermarket battery – not OEM. Cells may have lower cycle life or less consistent voltage under heavy load compared to genuine EGO packs. Check reviews for long-term performance.
• Installation: No tools required – simply slide onto tool or charger until it clicks.
• Gotcha: The 12.0Ah capacity is high; it may take longer to charge (3-5 hours on standard charger). Also, aftermarket batteries sometimes lack the fuel gauge accuracy of OEM packs.
• Warranty: Typically 1-2 years from seller, not EGO. Verify return policy before buying.

Should You Buy It

Buy this if you need extended runtime for large lawns or heavy trimming and want to save ~$50-70 over an OEM EGO 12.0Ah pack. Skip it if you rely on precise fuel gauge readings or need the longest possible lifespan – OEM EGO batteries generally last more seasons.
