2Pack 40v 7500mAh Replacement for Ryobi 40V Battery 7.5Ah Compatible with Ryobi 40 Volt Battery Lithium OP4026A OP4015 OP4040 OP40201 OP4050A OP4015 OP40261 OP4030 OP40401 OP4060 Power Tools(2Pack)

What It Is

This is a 2-pack of aftermarket 40V lithium-ion batteries, each rated at 7500mAh (7.5Ah). Designed as a replacement for Ryobi 40V cordless lawn mowers, trimmers, blowers, and other 40V power tools, it offers extended runtime compared to standard 4.0Ah or 5.0Ah packs.

Fitment & Compatibility

• Fits Ryobi 40V tools that accept the standard slide-in battery platform (common across Ryobi 40V mowers, string trimmers, leaf blowers, chainsaws, etc.).
• Direct replacements for OEM models: OP4026A, OP4015, OP4040, OP40201, OP4050A, OP40261, OP4030, OP40401, OP4060.
• Check your tool’s battery slot – these are physically identical to Ryobi’s 40V pack; no adapter needed.
• Not compatible with Ryobi 18V One+ or 36V systems.
• Verify your mower’s battery compartment can accommodate the slightly larger 7.5Ah footprint – some older models have tight clearance.

Key Things to Know

• Aftermarket quality: Not OEM Ryobi. Expect slightly shorter lifespan and potential variation in charge capacity. Read recent reviews for batch consistency.
• Installation: Slide on, lock in – no tools required. Works with your existing Ryobi charger (40V fast charger or standard).
• Common gotcha: Some users report the battery indicator lights may not match actual charge level. Fully charge before first use.
• Weight: 7.5Ah packs are heavier than 4Ah – may affect balance on handheld tools (trimmers, blowers). Fine for mowers where weight is less critical.

Should You Buy It

Buy this if you need affordable extended runtime for heavy mowing or trimming sessions and don’t mind aftermarket trade-offs. Skip it if you prefer OEM reliability, need consistent battery gauge accuracy, or use tools where weight matters (e.g., pole saws). For the price of one OEM 7.5Ah, you get two here – but expect shorter overall service life.
