What It Is

This is a two-pack of high-capacity 7500mAh lithium-ion replacement batteries for Ryobi’s 40V cordless outdoor power tools—like mowers, trimmers, blowers, and chainsaws. It’s designed to give longer runtime than standard Ryobi 40V batteries, especially for larger mowing jobs or heavy-use tasks.

Fitment & Compatibility

  • Works with any Ryobi 40V tool that uses the standard OP-series battery platform (e.g., mowers, string trimmers, hedge trimmers, blowers, chain saws).
  • Direct replacement for OEM models: OP40261, OP4050, OP4040, OP40401, OP40201, OP40601.
  • Charger compatibility: Use with Ryobi OP401 charger or any Ryobi 40V charger (OP406A, OP408A, etc.).
  • Physical check: Same form factor as original Ryobi 40V batteries; slides into the tool’s battery port and clicks securely. No modifications needed.
  • Note: Not for 18V or 36V Ryobi tools—only 40V platform.

Key Things to Know

  • Capacity difference: 7500mAh is higher than many stock Ryobi batteries (typically 4.0–6.0Ah). Expect noticeably longer runtime, especially on high-draw tools like mowers.
  • Quality variance: Aftermarket batteries may have slightly less real capacity than claimed. Read recent reviews for batch consistency.
  • Installation: Zero difficulty—just slide in and click. No wiring, adapters, or tools required.
  • Common gotcha: Some users report the battery won’t charge if deeply discharged; always store with partial charge and use a Ryobi charger that supports the higher capacity.

Should You Buy It

You should buy this if you own several Ryobi 40V tools and need longer runtime without swapping batteries mid-job, or if your original batteries are worn out and you want an affordable high-capacity upgrade. It’s not for light, occasional use—stick with OEM if you prefer guaranteed fit and warranty support.
