FERRYBOAT 56V 5.0Ah Compatible with EGO 56V Battery Lithium Replacement for EGO 56V Max Battery BA2800 BA4200T BA4200 BA1400 BA2800T BA5600T Power Tools Battery 1PACK

What It Is

This is an aftermarket 56V 5.0Ah lithium battery replacement designed to power EGO 56V cordless lawn mowers, trimmers, blowers, and other outdoor power tools that use the EGO ARC-Lithium platform.

Fitment & Compatibility

• Compatible EGO battery models: BA2800, BA4200T, BA4200, BA1400, BA2800T, BA5600T
• Works with: All EGO 56V tools that accept the standard slide-on battery interface (most models after 2012)
• Check before buying: Verify your tool’s voltage requirement is 56V and that it uses the same slide-on mounting. This battery is not compatible with EGO 56V backpack models or chargers that require a proprietary communication chip (e.g., some newer rapid chargers may not fully charge aftermarket packs).
• Physical dimensions: Approximately 5.5” x 4” x 3.5” – confirm clearance in your mower’s battery tray. Slightly thicker than OEM BA1400, so may not fit tight compartments.

Key Things to Know

• No tools needed – slides directly onto the tool’s battery mount; installation is identical to OEM.
• Capacity is 5.0Ah – matches BA2800 and BA4200 runtime. Expect 30–45 minutes of mowing on a standard 21” mower, depending on grass conditions.
• Aftermarket quality varies – 4.3 rating is decent, but some users report shorter lifespan (1–2 seasons) versus OEM (3–4 seasons). Check return policy.
• Charging note – Use your original EGO 56V charger. This battery lacks the communication chip found in newer EGO packs, so it may not charge if your charger has a firmware lock (rare but possible on very recent chargers).

Should You Buy It

Buy this if you need a spare battery for occasional use or own multiple EGO 56V tools and want to save roughly 40–50% over OEM. Avoid it if you rely on the tool daily for commercial work, need the longest possible lifespan, or have a very new EGO charger (post-2022) that might reject aftermarket packs.
