2Pack 7500mAh Extend Capacity Replacement for Ryobi 40 Volt Battery Lithium and OP401 Charger Compatible with Ryobi 40v Battery OP40401 OP4026 OP40261 OP4050 OP40601 OP40602 Cordless Tools (Green)

What It Is

This is a 2-pack of high-capacity 7500mAh replacement batteries for the Ryobi 40V cordless platform. Designed to power any Ryobi 40V tool (mowers, trimmers, blowers, chainsaws) and compatible with the OP401 charger, they offer extended runtime compared to standard 40V batteries.

Fitment & Compatibility

• Tool Compatibility: Fits all Ryobi 40V cordless tools and equipment (lawn mowers, string trimmers, leaf blowers, hedge trimmers, chainsaws). Common models include OP40401, OP4026, OP40261, OP4050, OP40601, OP40602.
• Charger Compatibility: Works with the Ryobi OP401 charger (and most other Ryobi 40V chargers). Do not use with 18V or other voltage chargers.
• Physical Fit: Same size and slide-mount as OEM Ryobi 40V batteries. No adapter needed; slides directly into tool battery port.
• What to Check Before Buying:
  • Confirm your tool uses Ryobi 40V (not 18V ONE+ or 80V).
  • Verify your charger model is compatible (OP401 is confirmed; most Ryobi 40V chargers work).
  • If using in a mower, ensure the battery compartment can accommodate the slightly taller profile (some mowers have tight lids—measure if unsure).

Key Things to Know

• Capacity: 7500mAh vs. standard 4000–5000mAh OEM batteries—expect 30–50% longer runtime per charge.
• Quality: Aftermarket, not OEM. Reviews are mixed on long-term durability; some users report cell degradation after 1–2 seasons. Check warranty (typically 1 year).
• Installation: No tools required. Slide battery into tool until it clicks. Press release tab to remove.
• Gotchas:
  • May not fit mowers with a sealed, non-removable battery tray (check your mower model).
  • Heavier than OEM (approx. 2.5 lbs each) due to larger cells.
  • Some users note the green color doesn’t match Ryobi’s standard green.

Should You Buy It

Buy this if you need extended runtime for heavy mowing or trimming sessions and are comfortable with aftermarket batteries at a lower price than OEM. Skip it if you prioritize long-term reliability, need a perfect color match, or use tools with tight battery compartments.
