DTK Replacement for EGO 56V Battery 5.0Ah BA2800 BA2800T BA1400 BA1400T BA4200 BA4200T Cordless Tool Batteries

What It Is

This is a 56V, 5.0Ah aftermarket lithium-ion battery designed to power EGO cordless lawn mowers, trimmers, blowers, and other 56V tools. It replaces the OEM BA2800, BA2800T, BA1400, BA1400T, BA4200, and BA4200T models.

Fitment & Compatibility

• Works with: All EGO 56V tools (lawn mowers, string trimmers, leaf blowers, chainsaws, etc.) that accept the standard EGO slide-on battery pack.
• Does NOT fit: EGO 56V tools requiring a different battery form factor (e.g., backpack batteries or older 56V models with unique connectors). Check your tool’s manual for “56V ARC Lithium” battery type.
• Physical size: Same dimensions as OEM BA2800/BA1400 (approx. 5.5 x 4.5 x 3.5 inches). Measure your battery compartment if unsure.
• Voltage: 56V nominal (same as OEM). Do not use in 40V or 80V tools.
• Aftermarket note: This is not an EGO-branded battery. It uses the same slide-on interface but may have slightly different plastic molding. Confirm the latch alignment and terminal pins match your tool before purchase.

Key Things to Know

• Quality: Aftermarket batteries often use lower-grade cells than OEM. Expect slightly shorter runtime and a higher chance of early capacity loss (typically 1-2 years vs. 3-5 years for genuine EGO).
• Installation: Zero difficulty—slide onto tool until it clicks. No tools or wiring required.
• Common gotcha: Some EGO chargers (especially newer ones) may not recognize aftermarket batteries. If the charger shows a red flashing light, the battery may be incompatible. Test with your charger first.
• Warranty: Typically 1-year limited (check seller). OEM batteries have 3-year warranty. This is a budget trade-off.

Should You Buy It

Buy this if you need a spare battery for light-to-moderate use and want to save 40-50% over OEM cost. Skip it if you rely on your EGO tools daily, need maximum runtime, or want the reliability of a genuine EGO battery with full warranty support.
