7.5Ah Replacement for Ryobi 40V Battery and Dual Charger Combo Compatible with Ryobi 40V Lithium Battery OP4040 OP4026 OP40601 OP4050A OP4030 OP4050 OP40201 OP40401 (2Battery+1Charger)

What It Is

This is a 7.5Ah replacement battery and charger combo for Ryobi 40V cordless lawn equipment—mowers, trimmers, blowers, and chainsaws. It includes two high-capacity batteries and a dual charger, designed for users who need longer runtime and a backup charging setup.

Fitment & Compatibility

• Check your equipment voltage: Only works with Ryobi 40V tools (not 18V or 36V systems).
• OEM vs. aftermarket: This is a third-party replacement, not Ryobi OEM. It’s compatible with Ryobi 40V battery models OP4040, OP4026, OP40601, OP4050A, OP4030, OP4050, OP40201, and OP40401.
• Physical fit: Measure your existing battery compartment depth and width. The 7.5Ah battery is physically larger than standard 4Ah or 5Ah packs—may not fit under some mower decks with tight battery shrouds. Test clearance before use.
• Charger compatibility: The included dual charger works with all listed Ryobi 40V batteries, but may charge slower than Ryobi’s own rapid charger.

Key Things to Know

• Installation: No tools needed—slide battery onto tool until it clicks. Charger requires standard 120V outlet. Fully charge both batteries (4–6 hours each) before first use.
• Quality note: With only 1 review (4.0 stars), long-term reliability is unproven. Third-party batteries sometimes have shorter lifespan or lower cold-weather performance than OEM.
• Common gotcha: The 7.5Ah capacity means longer runtime (up to 60–90 minutes on a mower), but heavier weight—adds ~1 lb per battery. May cause fatigue on handheld tools.
• Warranty: Check seller’s return policy. Many third-party batteries have limited or no warranty compared to Ryobi’s 3-year OEM coverage.

Should You Buy It

Buy if you need a budget-friendly spare set for a single Ryobi 40V mower or trimmer and don’t mind the extra weight and unknown long-term reliability. Skip if you want guaranteed fit under tight mower decks, need fast charging, or prefer OEM warranty support for heavy daily use.
