2Pack 7.0Ah Replacement for Ryobi 40V Lithium Battery Compatible with Ryobi 40 Volt Battery OP4050A OP40601 OP4026A OP4040 OP4030 OP4050 OP40501 OP4015 OP40261 OP40201 OP40401 OP40602 Cordless Tools

What It Is

This is a 2-pack of 7.0Ah replacement lithium batteries for Ryobi’s 40V cordless lawn mowers, string trimmers, blowers, and other 40V tools. Each battery delivers 7.0 amp-hours for extended runtime compared to standard 4.0Ah or 5.0Ah packs.

Fitment & Compatibility

These batteries are a direct replacement for Ryobi 40V models including OP4050A, OP40601, OP4026A, OP4040, OP4030, OP4050, OP40501, OP4015, OP40261, OP40201, OP40401, and OP40602. They fit all Ryobi 40V tools and chargers that accept the standard slide-on battery interface. Before buying, verify your tool’s voltage (must be 40V) and that the battery slides on without forcing—some older Ryobi 40V tools (pre-2015) may have slightly different latch designs. Measure the battery compartment: the 7.0Ah pack is larger than 4.0Ah units, so check clearance in mowers with tight battery wells (e.g., some push mowers). Aftermarket, not OEM, so warranty and performance may differ.

Key Things to Know

• Quality & Safety: Aftermarket batteries may lack the overcharge/overheat protection circuits found in genuine Ryobi packs. Use only with a Ryobi 40V charger and avoid leaving on charge unattended.
• Installation: No tools needed—slide the battery onto the tool until it clicks. If it doesn’t seat fully, check for debris or latch misalignment.
• Gotcha: The 7.0Ah capacity means longer runtime, but it also adds weight (~2.5 lbs per pack). On handheld tools like trimmers, this can cause fatigue.
• Common Issue: Some users report the battery indicator lights not matching genuine Ryobi behavior—lights may stay on briefly after removal or show charge inaccurately.

Should You Buy It

Buy this if you need affordable backup batteries for multiple Ryobi 40V tools and don’t mind trading OEM reliability for lower cost. It’s a good fit for budget-conscious owners of compatible mowers, trimmers, or blowers who want longer runtime per charge. Skip it if you prioritize safety certifications, warranty support, or consistent charge reporting—stick with genuine Ryobi packs.
