2Pack 6.0Ah Replacement for Ryobi 40V Battery Lithium-ion Batteries Compatible with Ryobi 40 Volt Battery OP4026A OP4040 OP4030 OP4050 OP4060 and Power Tools

What It Is

This is a 2-pack of 6.0Ah lithium-ion replacement batteries for Ryobi 40V cordless outdoor power tools—lawn mowers, trimmers, blowers, chainsaws, and more. Each battery delivers higher runtime than the standard 4.0Ah or 2.6Ah packs, ideal for larger yards or extended use.

Fitment & Compatibility

• Brand & voltage: Designed for Ryobi 40V tools and chargers only. Not cross-compatible with 18V or 36V Ryobi systems.
• Compatible models: Works with OEM battery part numbers OP4026A, OP4040, OP4030, OP4050, OP4060, and all Ryobi 40V tools using those packs.
• Physical fit: Same shape and slide-in interface as OEM packs. Fits Ryobi 40V mowers (e.g., RY40180, RY401150), trimmers, blowers, and chain saws. No deck size or blade compatibility needed—just verify your tool uses the standard Ryobi 40V slide-in battery.
• What to check: Ensure your charger is a Ryobi 40V charger (not an older 18V charger). Aftermarket batteries may have slightly different LED indicators or button placement, but the rail and connector are identical.

Key Things to Know

• Quality vs. OEM: These are aftermarket replacements, not Ryobi-branded. They may have slightly shorter lifespan or lower cold-weather performance than genuine Ryobi packs, but reviews are generally positive for the price.
• Installation: None required—just slide onto the tool until it clicks. No wiring or tools needed.
• Charging: Use only a Ryobi 40V charger (OP4060, OP4080, or any charger labeled for 40V). Do not use a 18V charger—risk of fire or damage.
• Common gotcha: Some users report the battery indicator lights are less accurate than OEM. If your tool cuts out early, try re-seating the battery or charging fully.

Should You Buy It

Buy this if you need extra runtime for a large lawn or multiple 40V Ryobi tools and want a budget-friendly alternative to OEM packs. It’s not a good choice if you demand OEM-level reliability in freezing temps or need a warranty from Ryobi. For occasional to moderate use, it’s a solid value.
