Frequently Asked Questions

  • Does this battery come with a charger?

    No, this model does not come with a charger.

  • Which tools are compatible with this battery (WA3580)?

  • How much does this battery weigh?

    Each 40V battery (WA3580) weighs about 1.5 lbs!

  • How long can you trim on each 40 Volt Max Lithium battery charge?

    On the Worx 40V GT 3.0 STRING TRIMMER / EDGER, each 40 Volt Max Lithium Battery will provide enough working time per charge to trim up to the average 1/2 acre yard. Actual results may vary depending on the density of the grass or weeds you’re cutting, the amount of trimming versus edging, and the age of the battery pack.

  • How long does it take to charge the 40 Volt Max battery?

    It takes about 8 hours to fully charge the battery with a standard charger (WA3742), or about 2 hours with the dual-port charger (WA3877).

  • Are the 40 Volt Max Lithium batteries interchangeable with the 32 Volt Max Lithium Battery?

    While Share Volt allows you to share batteries between tools within the same voltage family, batteries should only be used with tools of a corresponding voltage. Use your 40V Max Lithium battery with any 40V Worx tool – even the power tools – but save your 32V battery for your 32V tools.

  • Are lithium batteries interchangeable with the Ni-Cad?

    Our lithium tools and Ni-Cd tools are separate platforms and are not interchangeable. Lithium batteries offer our customers maintenance-free technology without the hassle of managing the memory effect inherent in Ni-Cad batteries.

    The Worx WA3747 40V charger and the dual-port charger (WA3877) are compatible with the 40V batteries. Charging times will vary by style of charger.

    Regardless of the tool or job at hand, we recommend that our customers follow standard safety precautions while using our tools, including wearing safety eyewear, gloves, appropriate shoes and clothing, and keeping hair tied back. Always refer to the owner’s manual for complete safety information before operating any tool.

What is the average run time for the 40v vs. the 20v?  I recently bought the 20v trimmer/blower combo pack with 2 batteries, and have had the 24v trimmer in the past. Is the total run time for the 40v the same as 2 20v batteries?
