(1) - 20V MAXLITHIUM BATTERY

The Worx 20V 4.0Ah battery is compatible with all 20V Worx tools – both garden tools and power tools! PowerShare lets you share the battery and save money.

The 4.0Ah 20V battery (WA3578) weighs about 1.4lbs.

On the Worx GT 2.0 String Trimmer/Edger/Mini-Mower, each 4.0Ah 20 Volt Max Lithium Battery will provide enough working time per charge to trim up to the average 1/2 acre yard. It’s like having two 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.

It takes about 10 hours to fully charge the battery with a standard charger (WA3742), or two hours with a quick charger (WA3868).

The Worx GT 2.0 features our highest capacity battery to date. This 20 Volt Max Lithium Battery has an amp hour rating of 4.0 vs our previous models (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 4.0 Ah battery (WA3578) can hold twice the amount of energy as previous models (WA3525). This extra capacity provides up to double 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 WA3742 20V charger and the Worx WA3868 20V quick charger are compatible, along with WA3835, WA3764, and WA3875. Charging times will vary by style of charger.

The difference between our Worx 20V batteries is their amp hour rating. The amp hour rating measures how much energy can be stored in the battery (energy capacity). The 20V Worx 4.0 Ah battery (WA3578) can hold twice the amount of energy as previous models (WA3525). This extra capacity provides double the run time.

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 the 4.0Ah 20V MaxLithium Worx battery isn’t the 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. For more information, click here.
