2 Pack 40V 6.0Ah Battery and Charger Replacement for Ryobi 40V Battery and Charger Combo Compatible with Ryobi 40 Volt Cordless Power Tools

What It Is

This is a 2-pack of 40V 6.0Ah lithium-ion batteries and a compatible charger, designed as a replacement for Ryobi 40V cordless lawn mowers, trimmers, blowers, and other 40V tools. It’s for users needing extra runtime or a backup set.

Fitment & Compatibility

• Check your tool’s voltage: Only works with Ryobi 40V (not 18V or 80V) tools.
• Battery shape: Uses the standard Ryobi 40V slide-on interface; fits most 40V models (e.g., RY40180, RY40250 mowers; RY40440 trimmer). Avoid if your tool uses a different mount (rare, but verify).
• Charger compatibility: The included charger is a standard 40V charger (likely 1.5A slow charger). Works with original Ryobi 40V batteries too, but not with 18V or other brands.
• OEM vs aftermarket: This is a third-party replacement, not Ryobi OEM. May have slight fit tolerances—test on a level surface before use. Check battery pack dimensions (approx. 6 x 4 x 3 inches) to ensure clearance in your mower’s battery compartment.
• What to measure: Confirm your mower/deck accepts a 6.0Ah battery (larger than 4.0Ah) without blocking the handle or deck.

Key Things to Know

• Quality variance: 4.1 stars with 29 reviews suggests decent performance, but some users report shorter lifespan than OEM. Expect 1-2 seasons of heavy use.
• No installation needed: Batteries slide on; charger plugs into standard 120V outlet. No tools required.
• Common gotcha: The charger may be slower than Ryobi’s 4A rapid charger (takes 4-6 hours for a full charge). Plan accordingly.
• Warranty: Third-party replacements typically have 30-day to 1-year warranty—check listing details. OEM Ryobi batteries have 3-year warranty.

Should You Buy It

Buy this if you need a budget-friendly spare set for light-to-moderate lawn work and don’t mind slower charging. Skip it if you rely on your mower for large lawns (over 1/2 acre) or want OEM reliability and faster charging—stick with genuine Ryobi 40V 6.0Ah batteries.
