Futurebatt 2 Packs 6000mAh Replacement for Ryobi 40V Battery OP40601 OP4040 OP40401 OP4026 OP40261 OP4050A Compatible with Ryobi 40 Volt Max Cordless Power Tools

What It Is

This is a set of two 40V, 6000mAh lithium-ion replacement batteries designed for Ryobi 40V Max cordless lawn mowers, trimmers, blowers, and other outdoor power tools. They serve as a direct aftermarket alternative to Ryobi’s OEM OP40601, OP4040, and similar packs.

Fitment & Compatibility

• OEM models replaced: OP40601, OP4040, OP40401, OP4026, OP40261, OP4050A.
• Tool compatibility: Any Ryobi 40V Max tool or charger that accepts the standard slide-on battery interface. This includes most Ryobi 40V mowers, string trimmers, leaf blowers, chainsaws, and hedge trimmers.
• Physical check: Measure your existing battery’s dimensions (approx. 6.5” x 3.5” x 4.5”) and confirm the slide rails and terminal layout match. Futurebatt packs are slightly taller than some OEMs—verify clearance in your mower’s battery compartment.
• Charger note: Works with any Ryobi 40V charger, including OP40401 and OP40301.

Key Things to Know

• Capacity vs. OEM: 6000mAh is higher than Ryobi’s standard 4.0Ah (4000mAh) packs, giving longer run time but slightly heavier weight (~2.5 lbs each).
• Installation: No tools required—slide on until latch clicks. Ensure the battery is fully seated; a loose connection can cause intermittent power loss.
• Quality & lifespan: Aftermarket batteries may have shorter cycle life than OEM. Avoid deep discharges (recharge before tool stops) and store in moderate temps to maximize life.
• Warranty: Futurebatt typically offers 1-2 years, but check seller policy. Single review at launch—low track record.

Should You Buy It

If you own multiple Ryobi 40V tools and need a budget-friendly backup set for longer mowing sessions, this two-pack is a solid value at ~$40 per battery. However, with only one review and unknown long-term reliability, it’s best for occasional users who don’t mind some risk. For heavy daily use, stick with genuine Ryobi batteries.
