BA2800T 5.0Ah Replacement for EGO 56V Battery Compatible with EGO Battery 56V Outdoor Tools, Lithium-Ion Battery Pack for Mowers, Blowers, Chainsaws, and Charger

What It Is

The BA2800T is a 5.0Ah lithium-ion replacement battery pack designed to power any EGO 56V cordless outdoor tool—mowers, blowers, chainsaws, trimmers, and hedge trimmers. It functions as a drop-in power source, compatible with the EGO 56V charger system.

Fitment & Compatibility

• Voltage & chemistry: Must match EGO’s 56V ARC Lithium platform. This is a third-party replacement, not an OEM EGO battery.
• Tool compatibility: Fits all EGO 56V tools (including mowers with deck sizes 16–21 inches, blowers, chainsaws, etc.) that accept the standard slide-on battery interface.
• Charger compatibility: Works with EGO 56V standard and rapid chargers (model numbers CH5500, CH2800, CH7000, etc.). Double-check your charger’s voltage rating—do not use with 40V or 80V chargers.
• Physical fit: Same form factor as OEM 5.0Ah battery (BA2800, BA2800T). Measure your battery bay depth if using a mower with a tight compartment—third-party batteries can be slightly thicker.
• Warranty impact: Using a third-party battery may void your tool’s warranty. Confirm with EGO or your tool’s manual before purchasing.

Key Things to Know

• Quality variance: At 3.7 stars from 32 reviews, expect moderate build quality. Some users report shorter lifespan or reduced runtime compared to OEM EGO 5.0Ah batteries (which typically last 2–3 seasons).
• No “fuel gauge” LEDs: Most third-party replacements lack the 4-LED charge indicator found on genuine EGO batteries. You’ll need to test runtime or rely on tool’s low-battery warning.
• Installation difficulty: Trivial—slide onto tool, click lock. No wiring or modification needed.
• Common gotcha: Charging may take longer with rapid chargers if the battery’s internal BMS (battery management system) is less efficient. Some users report the battery stops charging at 80–90% capacity.

Should You Buy It

Buy this if you need a spare battery on a tight budget and can accept reduced runtime, no charge indicator, and a shorter overall lifespan. Skip it if you rely on heavy daily use, need the LED fuel gauge, or want to keep your tool warranty intact—stick with OEM EGO BA2800T.
