56V Lithium-Ion 12.0Ah Battery Replacement for EGO Power+ Battery 56V BA6720T, 1-Pack

What It Is

This is a high-capacity 56V lithium-ion battery replacement for EGO Power+ lawn mowers and other 56V EGO tools. The 12.0Ah rating provides extended runtime for large lawns (typically 1–2 acres) or heavy use across multiple tools like string trimmers and blowers.

Fitment & Compatibility

• Exact replacement for EGO BA6720T – works with all EGO 56V tools (mowers, snow blowers, chainsaws, etc.).
• Check your tool’s voltage requirement – this is 56V, not 40V or 80V. Do not use on non-EGO brands.
• Physical size – measures roughly 8.5 x 5.5 x 6 inches; verify your battery compartment can fit this thicker 12.0Ah pack (some older EGO mowers may have tight clearance).
• OEM vs aftermarket – this is an official EGO replacement, not a third-party knockoff. It includes the same port and locking mechanism as original.
• No deck size or model number needed – if your tool takes a 56V slide-in battery, it will work.

Key Things to Know

• Runtime – delivers up to 2x the runtime of a standard 5.0Ah battery; expect 60–90 minutes of mowing on a 21” deck.
• Installation – slides into any EGO 56V tool’s battery slot; no tools required. Press the release button to remove.
• Charging – requires an EGO 56V charger (sold separately if not included). Charging time is ~60–90 minutes with a standard charger; faster with a turbo charger.
• Weight – about 3.5 lbs (heavier than smaller Ah packs). This can make handheld tools feel unbalanced; best for wheeled equipment or stationary use.

Should You Buy It

Buy this if you have a large lawn (½ acre or more) and already own an EGO 56V system. It’s ideal for minimizing mid-mow battery swaps, but skip it if you only need a backup for a small yard—a 5.0Ah or 7.5Ah battery will be lighter and cheaper.
