56V Lithium-Ion 5.0Ah Battery Replacement for EGO Power+ 56V BA2800T, 1-Pack

What It Is

This is a 56V 5.0Ah lithium-ion battery replacement for EGO Power+ outdoor equipment, designed to power mowers, trimmers, blowers, and other tools in the 56V Arc-Lithium platform. It’s a direct fit for the BA2800T model and is often used as a spare or replacement to extend runtime without waiting for a charge.

Fitment & Compatibility

• OEM vs. Aftermarket: This is an official EGO battery (not third-party), so it will work with all EGO 56V Power+ tools and chargers. No adapter needed.
• Model Number: Must match BA2800T or be listed as compatible with EGO’s 56V lineup. Check your tool’s battery part number (printed on the battery or in the manual) to ensure it’s the same voltage and connector style.
• Physical Fit: The 5.0Ah battery has the same dimensions as other EGO 56V batteries (e.g., BA1400, BA2800). It slides into any EGO 56V tool’s battery slot, but verify your tool model supports this capacity (most do, but older or smaller tools may lack the space for larger Ah packs).
• Charger: Works with any EGO 56V charger (CH5500, CH2800, etc.). No special charger required.
• What to Measure: If you’re replacing a different brand or size, measure the battery slot depth and width (roughly 6.5” x 3.5” x 4.5”) to confirm clearance.

Key Things to Know

• Quality & Performance: 5.0Ah provides a good balance of runtime and weight—about 45–60 minutes on a standard self-propelled mower (depending on grass conditions). It’s a genuine EGO cell, so you get consistent power delivery and no compatibility issues.
• Installation: Zero difficulty—just slide it into the tool until it clicks. No tools or wiring required.
• Common Gotchas:
  • The 5.0Ah battery is heavier than the 2.5Ah BA1400 (about 3.5 lbs vs. 2.2 lbs). This can affect balance on handheld tools like trimmers.
  • If your tool is older (pre-2015), check that the battery release latch aligns properly—most do, but a few early models had slightly different tabs.
  • Do not store fully discharged for long periods; EGO batteries have a built-in BMS but still benefit from partial charges if not in use.

Should You Buy It

If you already own EGO 56V gear and need a reliable spare or replacement with more runtime than the 2.5Ah pack, this is a solid buy. It’s a genuine OEM part with no fitment guesswork and good reviews. Skip it if you have a 2.5Ah charger that’s slow (this battery will take longer to charge) or if you need the highest capacity (6.0Ah or 7.5Ah) for heavy mowing. Right for most homeowners with one or two EGO tools.
