2 Pack 40V 6.0Ah Replacement for Ryobi 40V Battery OP4060A1 0P40601 0P4075A OP4050A OP4026A OP40201 0P4040 0P401 Lithium-lon Compatible with Ryobi 40 Volt Cordless Power Tool

What It Is

This is a 2-pack of 40V 6.0Ah lithium-ion replacement batteries for Ryobi 40V cordless lawn mowers, trimmers, blowers, and other outdoor power tools. Each battery provides higher capacity than the standard 4.0Ah or 5.0Ah packs, extending runtime for larger yards or heavy-duty tasks.

Fitment & Compatibility

• Direct replacement for Ryobi models: OP4060A1, 0P40601, 0P4075A, OP4050A, OP4026A, OP40201, 0P4040, 0P401.
• Fits all Ryobi 40V tools (lawn mowers, string trimmers, leaf blowers, chainsaws, etc.) using the standard 40V slide-on interface.
• Check your tool’s model number – if it’s a Ryobi 40V tool, this battery will physically connect and power it. No adapter needed.
• Not compatible with Ryobi 18V One+ or 36V systems, or with other brands (Greenworks, Kobalt, etc.).
• Measurements: Same footprint as OEM 5.0Ah/6.0Ah packs. Ensure your charger supports 6.0Ah (most Ryobi 40V chargers do, but older 1.5A chargers may take longer). If you have a rapid charger (2.5A or higher), you’re fine.

Key Things to Know

• Quality vs. OEM: Aftermarket, not genuine Ryobi. Some users report slightly shorter lifespan or faster capacity fade than OEM. Check warranty (often 1 year vs. 3 years on official Ryobi).
• Installation: Slide on until it clicks. No tools required. Ensure battery is fully seated to avoid power loss during mowing.
• Common gotcha: The included charger (if any) is not always included in this pack – verify you’re buying just batteries or a kit with charger. Some listings are battery-only.
• Runtime: 6.0Ah gives roughly 20–30% more runtime than a 5.0Ah on a mower (e.g., 45–60 minutes vs. 35–45 minutes, depending on grass conditions). Use for larger lawns (1/2 acre or more) to avoid mid-job swaps.

Should You Buy It

Buy this if you own multiple Ryobi 40V tools, need extended runtime for a large lawn, and want to save money over OEM batteries. Skip it if you demand OEM reliability, need a warranty longer than 1 year, or only have smaller tools where a 4.0Ah pack already suffices.
