56V Battery Replacement for EGO Power+ Battery 56V, 7.5Ah - BA4200T, 1-Pack

What It Is

This is an OEM replacement battery for EGO’s 56V cordless outdoor power equipment line. The 7.5Ah BA4200T is designed for high-drain tools like mowers, trimmers, blowers, and chainsaws, offering extended run time for larger yards (0.5+ acres).

Fitment & Compatibility

• Voltage & platform: Only works with EGO’s 56V ARC Lithium system. Not compatible with 40V, 80V, or other brands.
• Model match: Direct replacement for BA4200T. Also fits BA2800, BA1400, and BA1120 slots, but run time will vary.
• Mower fit: Fits all EGO push mowers (LM2000, LM2100, LM2102SP, etc.) and select self-propelled models. Check your mower’s battery compartment depth—some older models have a tight fit for the 7.5Ah’s taller profile.
• What to measure: Battery dimensions are ~7.5 x 4.5 x 5.5 inches. Measure your compartment if upgrading from a smaller Ah battery.

Key Things to Know

• Genuine vs. clone: This is an OEM EGO part, not third-party. It includes the fuel gauge button and charge indicator. Third-party 56V batteries often lack overcharge protection and may not fit securely.
• Installation: Slide in until latch clicks. No tools required. If it doesn’t click, check for debris in the slot or bent terminals.
• Run time: 7.5Ah gives ~45–60 minutes on a standard mower (depending on grass height). Roughly 1.5x the run time of the 5.0Ah BA2800.
• Common gotcha: Do not store fully discharged. EGO batteries can go into deep sleep if drained to zero. Recharge within 24 hours of use.
• Weight: ~3.5 lbs—heavier than smaller Ah packs. May affect balance on handheld tools.

Should You Buy It

Worth it if you already own EGO 56V gear and need a high-capacity OEM battery for larger lawns or heavy trimming. Skip if your yard is under 0.25 acres (a 5.0Ah is cheaper and lighter) or if you’re trying to cross-brand adapt—this only works in EGO’s own tools.
