Aoasur 5.0Ah Battery Replacement for EGO 56V Battery (Green-5.0AH)

What It Is

This is an aftermarket 56V 5.0Ah lithium-ion battery designed to power EGO lawn mowers, trimmers, blowers, and other 56V arc‑lithium tools. It’s a direct replacement for EGO’s original BA1400/BA2800/BA4200 batteries, offering similar runtime for medium‑duty residential jobs.

Fitment & Compatibility

• Works with: All EGO 56V products (mowers, string trimmers, leaf blowers, chainsaws, hedge trimmers, etc.) that accept the standard EGO slide‑on battery pack.
• Does NOT fit: EGO 56V backpack batteries or any tool requiring a different voltage or connector.
• Check before buying: Verify your tool’s model number ends in a 56V designation (e.g., LM2100, LB5300, ST1500). This battery is not compatible with 56V “Power+” or “Power Load” models that use a different battery shape.
• Measurement note: Physical dimensions are identical to OEM EGO 5.0Ah packs (approx. 5.5 x 3.5 x 4.5 inches). It fits all standard EGO battery compartments.

Key Things to Know

• Quality: Users report about 80–90% of OEM runtime (roughly 30–45 min on a 21” mower). Some units have minor fitment looseness; ensure the latch clicks securely.
• Installation: No tools needed – slides onto any EGO tool exactly like the original. Press the button to remove.
• Common gotchas: The battery indicator lights may be less accurate than OEM. Also, it won’t charge in EGO’s rapid chargers (use standard EGO 56V charger). Avoid leaving it fully discharged for long periods.
• Warranty: Typically 1–2 years (verify with seller). Not covered by EGO’s warranty.

Should You Buy It

If you need a spare battery for occasional use or have a tight budget, this is a decent value. It’s not as durable or long‑lasting as an OEM EGO battery, but for homeowners who mow a standard ¼‑acre lot once a week, it’ll get the job done. Skip it if you run your equipment commercially or need maximum runtime – go with a genuine EGO 5.0Ah or 7.5Ah pack instead.
