(1) - 20V MaxLithium Battery

The Worx 20V 6.0Ah battery is compatible with all 20V Worx tools – both garden tools and power tools! Power Share lets you share the battery and save money.

Check out the full line of compatible 20V Power Share tools.

The 6.0Ah 20V battery (WA3671) weighs about 1.7lbs.

On the Worx GT 2.0 String Trimmer/Edger/Mini-Mower, each 6.0Ah 20 Volt Max Lithium Battery will provide enough working time per charge to trim up to the average 3/4 acre yard. It’s like having three batteries in one! 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.

While the battery is compatible with any of the 20V battery chargers we have available, we recommend using the WA3868 quick charger, which will take about 3 hours to recharge the battery.

The 6.0Ah 20 Volt Max Lithium Battery has the highest amp hour rating we’ve offered to date compared to our previous models (4.0, 2.0, and 1.5 amp hour rating). The amp hour rating measures how much energy can be stored in the battery (energy capacity). The 20V Worx 6.0 Ah battery (WA3671) can hold up to three times the amount of energy as previous models (WA3525). This extra capacity provides up to triple the run time.

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 20V Max Lithium battery with any 20V Worx tool – even the power tools – but save your 32V battery for your 32V 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 WA3671 6.0 Ah 20V battery is compatible with any of the 20V chargers we offer. Charging times will vary by style of charger. To give you the fastest recharge available, we recommend using the WA3868 20V quick charger.

All of these models are 20V Worx batteries. The difference between them is their amp hour rating. A battery’s amp hour rating measures how much energy can be stored in the battery (energy capacity). The 20V Worx 6.0 Ah battery (WA3671) is our highest capacity battery to date. It can hold up to three times the energy as the WA3525 and 25% more than our 4.0 Ah battery (WA3578). This extra capacity provides up to triple the run time of our original 20V.

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 date of receipt (less shipping and handling). Please call our customer service center at 1-866-354-9679 (WORX) and we’ll be happy to assist. View more information here.

Worx batteries are covered by a 1 Year Limited Consumer Warranty and are not eligible for warranty extension.
