DTK Replacement for EGO 56V Battery BA1400 BA2800 BA4200, 56 Volt 2.6Ah Batteries Lighter Than 5AH (Easy to Carry, Light and not Tiring)

What It Is

This is an aftermarket 56-volt, 2.6Ah lithium-ion battery designed as a direct replacement for EGO’s BA1400, BA2800, and BA4200 power head batteries. It’s intended for use in EGO’s 56V cordless lawn mowers, trimmers, blowers, and other outdoor tools that accept the ARC-Lithium platform.

Fitment & Compatibility

• Works with any EGO 56V tool that uses the standard ARC-Lithium battery interface (most EGO mowers, string trimmers, blowers, chainsaws, and hedge trimmers).
• Does NOT fit EGO’s 56V “Power+” or “Select Cut” mowers that require the High-Efficiency (HE) battery (e.g., LM2100, LM2102SP). Check your tool’s battery slot – if it has a raised center rib, it’s an HE slot; this battery won’t lock in.
• OEM vs. Aftermarket: This is a third-party battery, not an EGO original. It uses the same physical dimensions and connector as the BA1400/2800/4200, but performance and longevity may differ.
• Measurements: ~4.9 x 3.5 x 5.5 inches, 1.5 lbs. Slightly lighter than a 5Ah EGO battery (about 1.8 lbs). Verify clearance in your tool’s battery compartment.

Key Things to Know

• Lighter weight – At 2.6Ah, this battery is noticeably lighter than a 5Ah or 7.5Ah pack, reducing fatigue during handheld use (trimmers, blowers). But runtime will be shorter (roughly half of a 5Ah).
• No installation required – Just slide it into the tool’s battery slot until it clicks. No wiring or tools needed.
• Charging – Works with EGO’s standard 56V charger (CH5500, CH2800, etc.). Charge time is similar to OEM 2.6Ah packs (~60 minutes).
• Common gotcha – Some users report the battery indicator lights don’t match OEM behavior (e.g., 3 lights may show at half charge). Also, aftermarket batteries may have a shorter lifespan (fewer charge cycles) than genuine EGO packs.

Should You Buy It

Buy this if you need a lightweight backup battery for handheld EGO 56V tools and want to save money over OEM (which costs ~$80-100). It’s a decent budget option for light-duty use – trimming, edging, or blowing – where the lighter weight helps. Skip it if you need maximum runtime for a mower or heavy-duty work, or if you want the reliability and warranty of an OEM battery.
