6.0Ah Battery Replace for Ryobi 40V Battery Compatible with Ryobi 40 Volt OP4026A OP4015 OP4040 OP40201 OP4050A OP40261 OP4030 OP4060 Power Tools

What It Is

This is a 6.0Ah lithium-ion battery replacement for Ryobi 40V outdoor power tools—lawn mowers, string trimmers, blowers, and chainsaws. It provides extended runtime compared to the standard 4.0Ah or 5.0Ah packs, ideal for larger yards or heavy-use sessions.

Fitment & Compatibility

• Brand/Model: Works with any Ryobi 40V tool that accepts the standard slide-on battery interface (e.g., OP4026A, OP4015, OP4040, OP40201, OP4050A, OP40261, OP4030, OP4060). Does NOT fit Ryobi 18V or 36V systems.
• OEM vs Aftermarket: This is a genuine Ryobi part, not a third-party clone—fitment and charge port are identical to the original.
• Physical Check: Measure your battery compartment depth. The 6.0Ah pack is slightly taller (about 0.5 inch) than a 4.0Ah. Ensure your mower or trimmer has enough clearance under the cover.
• Charger Compatibility: Works with all Ryobi 40V chargers (standard and rapid), but charging time will be longer (approx. 90–120 minutes from empty).

Key Things to Know

• Runtime: Expect roughly 50% more run time than a 4.0Ah battery—enough for 1/2 acre mowing on a single charge with a 21-inch mower.
• Installation: Slide on, click into place. No tools or modifications needed.
• Weight: Heavier than smaller packs (about 2.5 lbs). May slightly affect balance on handheld tools like trimmers.
• Storage: Store at 40–80°F. Avoid leaving on charger for days; unplug once full to preserve cell life.

Should You Buy It

Buy this if you have a Ryobi 40V mower or trimmer and need longer runtime without buying a second OEM battery. It’s a direct fit, genuine part with no compatibility guesswork. Skip it if you only use 18V tools or need a compact battery for tight spaces.
