DTK 5Ah Battery Replacement for EGO 56V Battery Compatible with BA2800 BA4200T BA4200 BA1400 BA2800T BA5600T 56V Batteries

What It Is

This is an aftermarket 56V 5.0Ah lithium-ion battery replacement for EGO cordless lawn mowers, trimmers, blowers, and other outdoor power equipment that uses the ARC-Lithium platform. It’s designed to power your tool when the original EGO battery wears out or you need a spare for longer runtime.

Fitment & Compatibility

Before buying, confirm your EGO tool uses the standard 56V ARC-Lithium battery interface (most EGO models do). This battery is not compatible with EGO’s older 56V batteries that have a different shape or with any other brand’s system. It is listed as a direct replacement for BA2800, BA4200T, BA4200, BA1400, BA2800T, and BA5600T packs, but it will also work with any EGO tool that accepts those batteries (e.g., mowers, string trimmers, leaf blowers, chainsaws). Check your tool’s manual or look for the battery model number on your current pack. Physical dimensions are roughly 5.5 x 3.5 x 4.5 inches; measure your battery compartment to ensure a snug fit. This aftermarket battery is not an OEM EGO product, so it may lack the same internal protection circuits.

Key Things to Know

• Quality & Safety: Aftermarket batteries may have lower-grade cells and fewer safety features (overcharge, over-discharge, thermal protection) than OEM EGO packs. Check for UL or CE certification marks on the unit.
• Installation: No tools required—slide the battery into the tool’s battery slot until it clicks. It should lock in place firmly; if it wobbles, it may not be fully seated.
• Runtime: 5.0Ah capacity is roughly equivalent to EGO’s BA2800 (2.8Ah) and BA4200 (4.2Ah) in terms of total runtime, but actual performance varies by tool and load. Expect slightly less runtime than a genuine EGO 5.0Ah battery due to cell efficiency.
• Charging: Uses EGO’s standard 56V charger (not included). Charge time is similar to OEM packs (about 60–90 minutes). Do not use a 12V or 24V charger.

Should You Buy It

If you need a budget-friendly spare battery for light to moderate use (e.g., trimming, blowing, or mowing a small lawn) and are comfortable with the slightly lower quality and potential safety trade-offs of an aftermarket pack, this is a decent value. For heavy daily use or if reliability and warranty support are critical, stick with a genuine EGO battery.
