The battery that runs an entire family of power and lawn & garden tools . the Worx 20V Power Share 2.0 Ah battery. It runs your cordless 20V & 18V Worx tools . and even pitches in to help power the 40V & 80V tools on the platform . too. (You’ll need two 20V batteries total for the 40V tools . and four batteries for the 80V tools.) It charges in about 5 hours . but you can get the 20V Quick Charger and fill it back up in about an hour (charger not included). It’s full of MaxLithium tech which makes it much more efficient than the older style of rechargeable batteries that would quickly lose the ability to hold a full charge. So you’ll be able to power drills and circular saws . leaf blowers and grass trimmers . Hydroshots and lawnmowers . over and over and over. It lasts longer than the previous 1.5 Ah model . so you can work longer before needing a recharge or swapping out to another battery. This WA3525 2.0Ah 20V Power Share battery makes a great addition to any existing Worx cordless tool collection. Extra batteries are always nice to have. It’s also an excellent way to start a tool collection with a cordless Worx tool that doesn’t come with a battery. Whichever it is . you’ll be pleased with this power-packed efficient little source of rechargeable energy. Get one and get to work!
