40V 6.0Ah Battery Replacement for SKIL 40V Battery Power Tools, Compatible with SKIL 40 Volt Lawn Mower, Leaf Blower & String Trimmer, Lithium-Ion High Capacity Batteries

What It Is

This is a high-capacity 40V 6.0Ah lithium-ion battery replacement for SKIL 40V power tools, including lawn mowers, leaf blowers, and string trimmers. It’s designed to extend runtime for larger yards or heavy-duty use.

Fitment & Compatibility

• Brand fit: Works with SKIL 40V tools only (not compatible with other brands like Greenworks, Kobalt, or Ryobi).
• Model check: Fits most SKIL 40V mowers, blowers, and trimmers (e.g., SKIL PWRCORE 40 series). Verify your tool’s voltage and battery slot shape before buying.
• OEM vs aftermarket: This is a third-party replacement, not SKIL-branded. It may have slight differences in latch fit or weight.
• Size: Dimensions are similar to OEM SKIL 40V 6.0Ah batteries (approx. 6.5 x 4.5 x 3.5 inches). Measure your battery compartment to ensure clearance.
• Charger compatibility: Works with SKIL 40V chargers (e.g., SKIL BY8703-00). Not compatible with 20V or 80V chargers.

Key Things to Know

• Quality: Rated 4.6/5 from 22 reviews, but aftermarket batteries may have shorter lifespan or slower charge time than OEM.
• Installation: Drops in like the original—no tools or wiring needed. Just slide into the battery port until it clicks.
• Gotcha: Some users report the battery indicator lights may not match OEM behavior (e.g., fewer LED segments).
• Safety: Lithium-ion cells can swell or fail if overcharged or stored in extreme heat. Use the included charger and store at room temperature.

Should You Buy It

Buy this if you already own a SKIL 40V tool and need a budget-friendly spare or a higher-capacity battery for longer runtime (e.g., mowing a 1/4-acre lawn). Skip it if you want guaranteed OEM reliability or need compatibility with non-SKIL tools.
