2Pack 7000mAh 40V Replacement for Ryobi 40V Battery Compatible with Ryobi 40 Volt Lithium Battery OP4026A OP4015 OP40602 OP40261 OP40401 OP40601 OP4050A OP40601 Compatible with 40V Cordless Tools

What It Is

This is a 2-pack of 7000mAh aftermarket 40V lithium batteries designed to replace Ryobi’s OEM 40V batteries. They power any Ryobi 40V cordless tool, including lawn mowers, string trimmers, blowers, and chainsaws.

Fitment & Compatibility

Check your tool’s voltage requirement—must be 40V. These batteries fit all Ryobi 40V tools that use the standard slide-in interface (common on models like OP4026A, OP4015, OP40602, OP40261, OP40401, OP40601, OP4050A). They are not compatible with Ryobi 18V or 36V systems. Confirm your charger: these work with Ryobi 40V chargers (OPC4040, OPC4060, etc.). Measure the battery compartment depth—these are slightly thicker than some OEM packs due to higher capacity.

Key Things to Know

• Capacity vs. OEM: 7000mAh is about 30% more runtime than a standard Ryobi 4.0Ah pack, but aftermarket cells may have lower peak current draw for heavy loads (e.g., thick grass on a mower).
• No Ryobi warranty: This is a third-party battery; Ryobi will not cover damage if it fails or causes tool issues.
• Installation: Slide on like OEM—no tools or adapters needed. Ensure the latch clicks firmly.
• Charging time: Expect 2–3 hours on a standard 40V charger; faster chargers (like 40V rapid) may reduce that but could stress aftermarket cells.

Should You Buy It

Buy it if you have multiple Ryobi 40V tools and want extended runtime at a lower cost than two OEM batteries. Skip it if you need guaranteed compatibility with heavy-draw tools (like a self-propelled mower) or if you rely on Ryobi’s warranty for peace of mind.
