2 Pack 7.5Ah High Capacity Replacement for Ryobi 40V Battery Compatible with Ryobi 40 Volt Battery Lithium OP40602 OP40401 OP4026 OP40261 OP4050 OP40601 OP4030 Compatible with 40V Cordless Tool

What It Is

This is a 2-pack of high-capacity 7.5Ah replacement batteries for Ryobi 40V cordless tools, including lawn mowers, trimmers, blowers, and chainsaws. Each battery provides longer runtime than the standard 4Ah or 5Ah packs, ideal for larger yards or heavy-use jobs.

Fitment & Compatibility

• Works with: Ryobi 40V battery platform tools (mowers, string trimmers, leaf blowers, hedge trimmers, chainsaws, etc.)
• Direct replacement for: Ryobi models OP40602, OP40401, OP4026, OP40261, OP4050, OP40601, OP4030.
• Not compatible with: Ryobi 18V or 36V systems, or any non-Ryobi brand tools.
• What to check: Ensure your tool has a 40V battery port (typically rectangular with a slide-on mount). Measure battery compartment dimensions: this pack is slightly taller than standard 4Ah units—about 5.5 inches tall—so confirm it fits under your mower’s battery cover or in the tool’s battery slot. Aftermarket, not OEM, so performance and lifespan may vary.

Key Things to Know

• Runtime: 7.5Ah delivers roughly 50% more runtime than a 5Ah battery—great for mowing 1/4 acre or more on a single charge.
• Charging: Use any Ryobi 40V charger (OP4080, OP4090, etc.). Charge time is about 2–3 hours from empty.
• Installation: Slide on, click in—same as OEM. No tools or modifications needed.
• Gotchas: Aftermarket batteries may have slightly shorter lifespan than OEM Ryobi. The fit under mower battery covers can be tight; measure your clearance first. Not all Ryobi 40V tools have the same battery release—check that the latch aligns with your tool.

Should You Buy It

Buy this if you have multiple Ryobi 40V tools, need extended runtime for large lawns or heavy tasks, and are comfortable with an aftermarket battery. It’s a solid value for the price, especially if you’re replacing old, worn-out OEM packs. Skip it if you prefer OEM reliability, have limited battery compartment space, or only need a single battery.
