7.5AH Battery Replacement for Ryobi 40V Battery Lithium Compatible with Ryobi 40 Volt OP4026A OP4015 OP4040 OP40201 OP40261 OP4060 Power Tool Capable of Handling the Cleaning Task (Green)

What It Is

This is a 7.5Ah lithium battery replacement for Ryobi’s 40V line, designed to power cordless lawn mowers, string trimmers, blowers, and other 40V tools. The higher capacity (7.5Ah vs. standard 4.0Ah or 5.0Ah) gives longer run time, ideal for larger yards or heavy cleaning tasks.

Fitment & Compatibility

• Check your tool’s voltage: Only for Ryobi 40V tools. Will not work with 18V or 36V systems.
• Compatible models: Works with OP4026A, OP4015, OP4040, OP40201, OP40261, OP4060, and most Ryobi 40V batteries (check your tool’s manual or battery port shape). Not OEM—third-party replacement.
• Physical fit: Same slide-on form factor as Ryobi 40V packs, but verify dimensions (approx. 6.5 x 4 x 3.5 inches) to clear battery compartment on mowers or handhelds.
• Charger compatibility: Works with standard Ryobi 40V chargers (OP401, OP406, etc.). Avoid using with fast chargers not rated for 7.5Ah—may cause overheating.

Key Things to Know

• Run time: Roughly 50% longer than a 5.0Ah pack. Expect 45–60 minutes on a push mower (depending on grass height and speed) or 2–3 hours on a trimmer.
• Installation: No tools needed—slides on and clicks. Ensure contacts are clean before first use.
• Quality note: Aftermarket battery; may not last as long as OEM Ryobi packs (cell quality varies). Check for UL/CE certification to reduce fire risk.
• Weight: Heavier than smaller packs (~3 lbs). Can make handheld tools feel unbalanced—fine for mowers but noticeable on long trimmer sessions.

Should You Buy It

Buy this if you have multiple Ryobi 40V tools and need extra run time for a large lawn or heavy-duty cleaning tasks, and you’re comfortable with an aftermarket battery to save money over OEM. Skip it if you prefer original parts for warranty peace of mind or if your tool’s battery compartment is tight—measure first to avoid return hassles.
