This battery is compatible with the WG191, WG291, WG591, WG771, WG772, and WA3859.

Each 56V battery weighs about 2 lbs.

On the Worx WG191 String Trimmer/Edger, each 56 Volt Max Lithium Battery will provide enough working time per charge to trim up to the average 1 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.

It takes about 90 minutes to fully charge the battery with the WA3859 charger .

While Power Share 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 56V Max Lithium battery with any 56V Worx tool, but save your 40V battery for your 40V tools.

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 WA3859 56V charger is compatible with the battery.

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.

If you decide this battery isn’t right for you, we offer a 30-day Money Back Guarantee from the date of receipt (less shipping and handling). View more information here.
