2Pack 7.0Ah Replacement for Ryobi 40V Lithium Battery Compatible with Ryobi 40 Volt OP4050A OP40601 OP4026A OP4040 OP4030 OP4050 OP40501 OP4015 OP40261 OP40201 OP40401 OP40602 Cordless Power Tools

What It Is

This is a 2-pack of 7.0Ah replacement lithium-ion batteries for Ryobi 40V cordless lawn mowers, trimmers, blowers, and other outdoor power tools. It’s a higher-capacity alternative to standard Ryobi 40V batteries, designed to extend runtime on compatible equipment.

Fitment & Compatibility

Check model numbers: This pack fits Ryobi 40V tools using batteries with model numbers OP4050A, OP40601, OP4026A, OP4040, OP4030, OP4050, OP40501, OP4015, OP40261, OP40201, OP40401, and OP40602. It will not work with Ryobi’s 18V or 36V systems.
Physical fit: The battery has the same slide-in interface as OEM Ryobi 40V packs, so it fits all Ryobi 40V tools and chargers (e.g., RY40500, RY40600 series mowers).
What to measure: Length ~5.5”, width ~3.5”, height ~4.5”. Verify your battery bay depth (some older mowers may have tight clearance).
Aftermarket note: This is not an OEM Ryobi battery—it’s a third-party replacement. May not charge on some newer Ryobi “IntelliPort” chargers (check charger model).

Key Things to Know

• Capacity vs OEM: 7.0Ah is larger than most stock Ryobi 40V batteries (usually 4.0Ah or 5.0Ah), giving longer runtime but adding weight (~2.5 lbs each).
• Installation: No tools needed—slide into tool battery port until it clicks. Remove by pressing release tab.
• Compatibility gotcha: Some Ryobi mowers (e.g., older 40V models) may not fully seat due to slightly thicker casing. Test fit before use.
• Quality: 5.0-star average from 23 reviews suggests reliable performance, but third-party cells may have shorter overall lifespan than OEM.

Should You Buy It

Buy this if you own multiple Ryobi 40V tools and want extra runtime for larger yards or heavy use, and you’re comfortable with aftermarket batteries. Skip it if you only need one battery or prefer OEM for warranty/charging reliability.
