5.0Ah Battery Replacement for EGO 56V Battery BA2800T, 2-Pack

What It Is

This is a 2-pack of 5.0Ah replacement batteries for EGO 56V arc-lithium lawn mowers, string trimmers, blowers, and other EGO POWER+ tools. Designed as a direct alternative to the OEM BA2800T, it powers medium-duty yard work without requiring a charger upgrade.

Fitment & Compatibility

• Voltage & Chemistry: Must be 56V arc-lithium (EGO’s proprietary system). Do not use on 40V or 80V tools.
• OEM Part Match: Replaces EGO BA2800T, BA1400, BA2240, BA4200. Fits all EGO POWER+ 56V tools (mowers, trimmers, blowers, chainsaws, etc.).
• Physical Check: Dimensions are 5.5 x 3.5 x 4.5 inches; weight ~2.2 lbs each. Verify your battery compartment depth (some older EGO mowers have tight slots).
• Charger Compatibility: Works with EGO CH5500, CH2800, CH2100, and CH7000 chargers. Not compatible with EGO’s rapid charger (CHV1600) without an adapter.
• Aftermarket Note: Not an OEM EGO product. If warranty coverage is critical, stick with genuine EGO batteries.

Key Things to Know

• Installation: Tool-free slide-on mount—just align the rails and push until it clicks. No wiring or screws.
• Performance: 5.0Ah provides ~45-60 minutes of mowing on a 20-inch deck (varies by terrain/grass). Less runtime than OEM BA2800T in cold weather (below 40°F).
• Common Gotcha: These batteries may not seat perfectly in some older EGO mowers (pre-2018 models) due to slightly thicker casing. Test fit before buying.
• Quality: User reviews note occasional cell imbalance after 50+ charge cycles. Keep the first charge to 8 hours to condition.

Should You Buy It

Buy this 2-pack if you need a budget-friendly backup set for multiple EGO 56V tools and don’t mind slightly shorter runtime than OEM in cold weather. Skip it if you rely on a single high-drain tool (like a 21-inch self-propelled mower) and demand maximum runtime per charge—stick with a single OEM 7.5Ah battery instead.
