About this item

Product details

Worx WA3678 20V Power Share PRO 8.0Ah Lithium-Ion High-Capacity Batteries were developed to unlock the full potential of Worx Nitro power and outdoor products, offering extended run times, more performance, and greater protection against heat and impacts than standard batteries. But they’re still compatible with every Worx Power Share 20V & 40V tool, outdoor power and lifestyle product, and will increase the run times of those tools. 

They feature an Intelligent Battery Management System (BMS) that monitors and optimizes each individual cell in the battery which maximizes overall performance, and cell-cooling technology employs thermoplastic material to keep the cells cooler, longer, which extends run time. 

The full-wrap 360-degree cell encasing provides protection against the tougher tasks that advanced DIY-ers and professionals put their tools through, with shielding against impacts, vibration, and excessive heat. And the conveniently-placed charge-level indicator offers a constant readout of available charge for each Power Share PRO battery. The charge level readout is helpful when estimating how much time you need to switch out or recharge your battery. 

These 8.0Ah models deliver 4X the capacity and up to 4X the run time of a standard 2.0Ah battery. Upgrade any of your Power Share products and get more from every charge. 

With a 30-day money back guarantee, if for some reason you decide that these batteries aren’t for you, and a 3-year limited warranty, you know Worx engineers are confident that these batteries will live up to the expectations of professional users. 

Power Share PRO batteries are 100% compatible with all Worx 20V, 40V, 80V tools, outdoor power and lifestyle products that display the Power Share or Power Share PRO logo. Although the WORX Power Share PRO high-capacity batteries come standard with Worx NITRO products, they can also be utilized on the traditional Worx products to achieve longer runtime. 

Worx recommends that Power Share PRO batteries be used with Worx NITRO products to unlock optimal performance.Power Share™ PRO batteries are the driving force behind the new Worx Nitro Series of power and outdoor products. They offer more performance, more run time, and more protection against heat and damage than standard batteries, and are still compatible with every Worx Power Share™ tool in the family.

PRO 8.0Am Battery

I was only able to mow about half of my yard with the 5.Ah batteries that came with my mower, but using the 8.Ah i was able to complete my entire lawn on one charge. I will say that the 8.Ah are quite expensive, actually cost more than my entire mower.

Excellent Purchase

Purchased this battery for my WR342 Vision Cloud 4wd robotic mower. Has extended the cutting time significantly and I am satisfied with its performance and quick delivery. Would highly recommend.

Gets timber jobs done with one pair of batteries

[This review was collected as part of a promotion.] Great for the high strain that the chain saw puts on the batteries. Lawn mower get the job done with spare to use in the string trimmer.
