Upgraded 2Pack 7000mAh Replacement for Ryobi 40V Battery Lithium Compatible with Ryobi 40 Volt Battery OP4050 OP4026 OP4050A OP40601 OP40602 OP4040 OP4030 OP4050 OP40261 OP40201 Cordless Tools

What It Is

This is an aftermarket 40V lithium-ion battery pack (7000mAh, 2-pack) designed to replace Ryobi’s OEM 40V batteries. It powers any Ryobi 40V cordless lawn mower, trimmer, blower, chainsaw, or other tool in the ONE+ 40V system.

Fitment & Compatibility

Before buying, check these:

• Model numbers: Compatible with Ryobi OP4050, OP4026, OP4050A, OP40601, OP40602, OP4040, OP4030, OP4050, OP40261, OP40201. If your tool uses a different Ryobi 40V battery model, it will likely still work—Ryobi’s 40V platform is cross-compatible across all 40V tools.
• Physical size: Measure your existing battery compartment (height, width, depth). Aftermarket packs can be slightly thicker/taller than OEM, so verify it slides in and locks without forcing.
• Voltage: Must be 40V nominal (this one is). Do not use on 18V or 36V tools.
• Charger: Works with any Ryobi 40V charger (model OP406, OP408, etc.). Not compatible with Ryobi 18V chargers.

Key Things to Know

• Capacity vs. OEM: 7000mAh is higher than Ryobi’s standard 4.0Ah or 5.0Ah packs. Expect longer run time, but weight is also higher—check if your tool handles the extra heft.
• Installation: Slide in like any Ryobi battery. Latch should click firmly. If it’s tight, do not force—verify fitment first.
• Quality notes: Aftermarket cells (likely Chinese) may have shorter lifespan or lower cold-weather performance than genuine Ryobi. Only 2 reviews—limited real-world data. No warranty details listed.
• Safety: Use only in well-ventilated areas. Do not store fully discharged. If pack gets hot during charging, stop immediately.

Should You Buy It

Buy this if you need a budget-friendly way to double your Ryobi 40V runtime and are comfortable with aftermarket electronics. Skip it if you prefer OEM reliability, need a warranty, or your tool requires a compact battery (e.g., handheld trimmers may feel unbalanced with the extra weight). For mowers and larger tools, it’s a decent value gamble.
