2Pack 40v Upgraded 7500mAh OP4026A Replacement for Ryobi 40V Battery 7.5Ah Compatible with Ryobi 40 Volt Battery Lithium 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 to replace Ryobi’s OP4026A and other 40V platform batteries. They’re intended for cordless Ryobi lawn mowers, string trimmers, blowers, chainsaws, and other outdoor power tools that use the 40V One+ system.

Fitment & Compatibility

Before buying, confirm your tool uses Ryobi’s 40V One+ battery platform (not the 18V system). These batteries are physically identical to the OEM OP4026A—same slide-on mount and terminal layout. Compatible models include OP4040, OP40201, OP4050A, OP4015, OP40261, OP4030, OP40401, and OP4060. Works with most Ryobi 40V mowers (e.g., RY40180, RY40190, RY401140) and other 40V tools. Do not use in tools that require a 36V or 18V battery. Check your tool’s manual or existing battery label for model number.

Key Things to Know

• Capacity vs. OEM: At 7.5Ah, these hold more charge than standard 4Ah or 5Ah Ryobi batteries, extending run time by 50-80% per charge. However, actual capacity may vary ±10% after break-in cycles.
• Installation: No tools required—slide the battery onto the tool until it clicks. Remove by pressing the release button. Ensure the battery is fully seated; a loose connection can cause intermittent power.
• Quality & Safety: Aftermarket batteries may lack internal protection circuits or cell balancing found in genuine Ryobi. Some users report shorter lifespan (1-2 seasons vs 2-3 for OEM). Use only with compatible chargers; do not mix with non-40V chargers.
• Common Gotcha: These batteries are slightly heavier than OEM 4Ah packs due to higher capacity. Check clearance on mowers with tight battery compartments—some users report a snug fit but no issues.

Should You Buy It

If you need extended run time for large lawns or heavy trimming and are comfortable with aftermarket performance trade-offs, this 2-pack offers good value at ~$41 per battery. However, if you prioritize long-term reliability, safety certifications, or seamless warranty support, stick with genuine Ryobi batteries (OP4026A or OP4040). Best for budget-conscious users who don’t mind replacing batteries more frequently.
