40V 6000mAh Replacement for Ryobi 40V Battery Compatible with Ryobi 40 Volt Battery OP4026 OP40602 OP4060A1 OP40601 OP4075A OP4050A OP4026A OP40201 OP4040 Lithium Ion(Multi-2PC)

What It Is

This is a 40V 6000mAh lithium-ion replacement battery designed to power Ryobi 40V cordless lawn mowers, trimmers, blowers, chainsaws, and other outdoor tools. It’s a higher-capacity aftermarket option (6000mAh vs. standard 4.0Ah/5.0Ah OEM batteries) for longer runtime on medium-to-heavy jobs.

Fitment & Compatibility

• Check your tool’s voltage: Only for 40V Ryobi tools (not 18V or 36V systems). The battery fits all Ryobi 40V ONE+ tools, including mowers, string trimmers, leaf blowers, and hedge trimmers.
• Model numbers: Compatible with OEM models OP4026, OP40602, OP4060A1, OP40601, OP4075A, OP4050A, OP4026A, OP40201, OP4040, and their variants. If your tool uses a slide-on 40V battery pack with a flat top, it’s likely compatible.
• Physical fit: Same dimensions as OEM Ryobi 40V batteries. Fits all Ryobi 40V battery slots without modification. No special adapter needed.
• Charger compatibility: Works with any Ryobi 40V charger (OP404A, OP406A, etc.). Do not use with 18V chargers.

Key Things to Know

• Aftermarket vs. OEM: This is a third-party replacement, not made by Ryobi. It may have slightly lower build quality and no official warranty from Ryobi. Check seller return policy.
• Installation: Fully plug-and-play. Slide onto tool or charger until it clicks. No tools required. Charge fully before first use (about 2–4 hours on a standard charger).
• Performance: 6000mAh = ~6.0Ah capacity. Expect 20–30% more runtime than a standard 4.0Ah OEM battery, but actual runtime depends on tool load and temperature.
• Common gotchas: Aftermarket batteries sometimes have shorter lifespan (fewer charge cycles) than OEM. Avoid deep discharge (tool cuts out) and store at room temperature. Some users report slight fit looseness on older tools—check for secure lock before use.

Should You Buy It

If you need a cost-effective spare or higher-capacity battery for heavy jobs (large lawns, thick brush, long trimming sessions) and don’t mind an aftermarket option, this is a solid choice. It’s not for users who demand OEM reliability or need a battery that lasts years of heavy commercial use. Best for homeowners with multiple Ryobi 40V tools who want extra runtime without paying Ryobi’s premium.
