56v 5.0Ah Replacement Battery for EGO 56V Battery BA2800 BA4200 BA1400, Compatible with EGO 56 Volt CS1604 CS1804 CS1403 HT2400 LB6504 LB5804 LB6500 LB4800 HTA2000 PH1400 Power Tools

What It Is

This is a 56V 5.0Ah lithium-ion battery replacement for EGO 56V outdoor power tools. It powers cordless lawn mowers, string trimmers, leaf blowers, chainsaws, hedge trimmers, and pole saws that use the same 56V Arc-Lithium platform.

Fitment & Compatibility

• Voltage & chemistry: Must be a 56V tool (not 40V or 80V). All EGO 56V tools use the same battery interface.
• Replaces OEM models: BA2800 (2.5Ah), BA4200 (4.0Ah), BA1400 (2.0Ah). It is not a direct replacement for the 7.5Ah BA5600T or 10Ah BA6720T (different shape/height).
• Compatible tools: CS1604, CS1804, CS1403 (chainsaws); HT2400 (hedge trimmer); LB6504, LB5804, LB6500, LB5800 (leaf blowers); HTA2000 (pole saw); PH1400 (power head). Also fits most EGO 56V mowers, trimmers, and snow blowers.
• Physical check: The battery base is identical to OEM, but overall height is slightly taller than the BA1400. Ensure your tool’s battery compartment has clearance (most do).
• Aftermarket note: This is not an EGO-branded battery. It may not have the same over-discharge or thermal protection circuitry. Check that your charger works with third-party batteries (some EGO chargers reject them).

Key Things to Know

• Run time: 5.0Ah provides roughly 2x the run time of a 2.5Ah battery. Expect ~30–45 minutes on a blower (high speed) or ~45–60 minutes on a mower (self-propelled).
• Charging: Works with EGO standard and rapid chargers. Charge time ~60–90 minutes with a standard charger.
• Installation: Drops in like OEM—no tools needed. Slide onto tool base until it clicks. Remove by pressing the release button.
• Common gotchas: Some users report the battery gauge LEDs are less accurate than OEM. Also, the plastic casing may feel slightly less rugged. Avoid fully draining it (recharge when tool slows).

Should You Buy It

If you need a spare or replacement for light-to-moderate yard work and want to save ~40% vs. the OEM BA4200, this is a solid value. But if you rely on your tools for heavy commercial use or need the most reliable battery management, stick with the genuine EGO.
