3000mAh Replacement for EGO 56V Battery, 56 Volt Lithium Ion Battery 3.0Ah Compatible with EGO 56 Volt BA2800 BA1400 BA4200 BA2800T BA4200T BA1400T ST1502LB CS1604 CS1804 CS1403 Cordless Power Tools

What It Is

This is a 3000mAh (3.0Ah) aftermarket lithium-ion battery replacement for EGO 56V cordless outdoor power tools. It’s designed to power mowers, trimmers, blowers, chainsaws, and other 56V EGO equipment that originally used BA1400, BA2800, BA4200, or similar packs.

Fitment & Compatibility

• Models it replaces: BA1400, BA2800, BA4200, BA2800T, BA4200T, BA1400T, ST1502LB, CS1604, CS1804, CS1403, and any EGO 56V tool that accepts the standard slide-on battery interface.
• What to check before buying:
  • Ensure your tool uses the slide-on battery mount (not the older push-in style).
  • Verify your charger is 56V compatible (most EGO chargers work with 2.0Ah–7.5Ah packs).
  • This is an aftermarket (non-OEM) battery—performance and longevity may differ from genuine EGO packs.
  • Physical dimensions: ~6.5 x 5.5 x 4 inches; weight ~2.2 lbs—fits all standard EGO 56V tool slots.

Key Things to Know

• Quality: Aftermarket cells may have lower cycle life and less consistent voltage under load compared to OEM. Some users report shorter runtime in high-draw tools (e.g., mowers, chainsaws).
• Installation: No difficulty—slide onto tool until it clicks. No wiring or modification needed.
• Common gotchas:
  • May not charge on all EGO chargers (especially older models); test with a known-working 56V charger.
  • Battery gauge (LEDs) may be less accurate than OEM.
  • Not compatible with EGO 56V backpack or Nexus power station adapters.

Should You Buy It

Buy this if you need a low-cost spare for light-duty use (trimmer, blower, edger) and are comfortable with aftermarket performance trade-offs. Skip it for heavy mowing or professional use where consistent runtime and reliability matter—stick with OEM EGO packs for those jobs.
