7.0Ah 40V Lithium Ion Replacement Battery for Ryobi 40V Cordless Power Tools, High Capacity 2-Pack Compatible with OP4050A OP40601 OP4040 OP4030 OP4050 OP40261 OP40201 OP40401

What It Is

This is a high-capacity 7.0Ah 40V lithium-ion battery 2-pack designed to power Ryobi 40V cordless lawn mowers, trimmers, blowers, chainsaws, and other tools in the Ryobi 40V platform. It offers extended runtime for larger yards or heavy-duty tasks.

Fitment & Compatibility

• Brand & Platform: Works with all Ryobi 40V cordless tools (e.g., mowers, string trimmers, hedge trimmers, blowers). Not compatible with Ryobi 18V or 36V systems.
• Model Numbers: Compatible with OP4050A, OP40601, OP4040, OP4030, OP4050, OP40261, OP40201, OP40401, and most Ryobi 40V tools using the standard slide-in battery interface.
• Physical Check: Measure your existing battery slot – this battery is slightly taller than some 4.0Ah or 5.0Ah packs. Ensure your mower’s battery compartment has clearance (especially under the handle or cover).
• OEM vs Aftermarket: This is an aftermarket replacement. It may not include a charge-level indicator or be fully compatible with Ryobi’s “IntelliPort” charger features. Test fit before relying on it for a job.

Key Things to Know

• Runtime: 7.0Ah provides roughly 40% more runtime than a standard 5.0Ah pack – good for mowing 1/3–1/2 acre on a single charge depending on grass conditions.
• Installation: No tools needed. Slides into any Ryobi 40V tool or charger. May feel slightly snug due to higher cell count; do not force.
• Charging: Works with any Ryobi 40V charger (e.g., OP40601, OP40401). Charge time is longer (about 90–120 minutes from empty) due to higher capacity.
• Gotcha: Not all Ryobi mowers have a battery lock that works perfectly with aftermarket packs – if your mower has a push-button release, check that the battery clicks in securely and doesn’t wobble.

Should You Buy It

If you need extended run time for a large lawn or use multiple 40V tools, this 2-pack offers good value. It’s ideal for Ryobi owners who want backup batteries without paying OEM prices. Skip it if you need a guaranteed fit with older mowers that have tight battery compartments, or if you rely on the OEM charge indicator.
