FirstPower Replacement for Ryobi 40v Battery and Charger Combo 7.0Ah Lithium OP4026 OP40601 OP4050A OP4040 OP4030 OP4050 with OP401 Ryobi 40v Battery Charger

What It Is

This is an aftermarket 40V 7.0Ah lithium-ion battery and charger combo designed to power Ryobi 40V cordless lawn mowers, trimmers, blowers, chainsaws, and other outdoor power equipment. It replaces original Ryobi models OP4026, OP40601, OP4050A, OP4040, OP4030, and OP4050, and includes the OP401 charger.

Fitment & Compatibility

• Check your tool’s voltage requirement: This only works with Ryobi 40V tools (not 18V, 36V, or 80V). Verify the battery port shape matches your tool—Ryobi 40V batteries use a slide-on mount with a single release button.
• OEM vs. aftermarket: This is not a genuine Ryobi battery. It will physically fit most Ryobi 40V tools, but some users report slight tolerance differences in the slide rails or latch mechanism.
• Measure the battery compartment: The 7.0Ah battery is physically larger (approx. 6.5 x 4 x 3.5 inches) than smaller-capacity Ryobi 40V batteries. Confirm your mower’s battery tray has enough clearance—especially under the handle or deck cover.
• Charger compatibility: The included OP401 charger works with all Ryobi 40V batteries, but it charges slower (about 2–3 hours for a full charge) than the rapid charger models (OP40601 or OP4080).

Key Things to Know

• No “fuel gauge” on battery: Unlike genuine Ryobi batteries, this FirstPower unit lacks the LED charge indicator button. You won’t know remaining charge without the tool’s own gauge or by testing.
• Installation is plug-and-play: No wiring, tools, or modifications needed. Slide the battery onto the tool’s mount until it clicks. Remove by pressing the release tab and pulling.
• Performance vs. OEM: Users report comparable runtime to a genuine 7.0Ah Ryobi battery, but slightly less peak power under heavy load (e.g., thick grass or mulching). It may cut out earlier than OEM in high-drain use.
• Warranty and safety: FirstPower includes a 1-year warranty. The battery has built-in overcharge, over-discharge, and short-circuit protection. Store in a cool, dry place to maximize lifespan.

Should You Buy It

Buy this if you need a budget-friendly spare or replacement for a Ryobi 40V tool and don’t require the LED fuel gauge or maximum peak power for heavy-duty jobs. It’s a solid value for light-to-medium use like trimming, blowing, or mowing small lawns. Skip it if you need rapid charging, absolute reliability for commercial use, or a perfect OEM fit.
