Amazing Battery
it doesn’t waste the battery as much but on the blower it does on my small 20 W but on the 40 W I do get a little bit more time to blow more grass off of my yard. I would recommend it. Also keep in mind that you’ll need to buy the fast charger dual setup. That will pay off in the future.

The ultimate accessory for a growing WORX tool collection. Charge two 20V Power Share batteries in an hour, or just one even faster so your tools never run out of power.

WORX - 20V Power Share and 18V Li-Ion Dual Port Battery Charger - Black

4.8(58)

Two slots are better than one when you’re a power user of Power Share tools and lawn & garden products. Charge up two 18V/20V batteries at the same time in about 2 hours, or just one even quicker. It’s portable enough to throw in your bag and take with you on the job or to a project. And its long cord gives you the flexibility to plug it in almost anywhere once you get there. It also makes an excellent permanent home charging station and is wall-mountable for just that purpose. Ideal for those with larger lawns, as you’re probably going to need more than one battery to trim or edge the whole yard. And if you’re enjoying our 40V Power Share tools, which use two 20V batteries, this charger will prove to be indispensable. Power Share is the cost-effective way to build out a whole tool and lawn & garden and lifestyle collection. Every Power Share battery runs every tool on the platform. Every string trimmer/ edger, every drill/driver, every mower, every chainsaw, every Hydroshot power washer. Those same batteries even power our MAKERX line of crafting and hobby tools. So you save money because you don’t have to buy a new battery every time you buy a new battery-powered tool. And a dual-port charger is a great way to make the most of that platform.

Questions & Answers

For the dual battery slot lawnmowers, can this battery be used on its own instead of 2 2.0Ah batteries or do both battery slots need to be filled for the mower to operate?
Hello there! Thank you for your inquiry. For WORX mowers with a dual-battery port, the mower typically requires two batteries of the same voltage and amp-hour rating to operate properly. To determine the specific compatibility of your battery with your tool, please send the model number of the tool to reviews@positecgroup.com. An agent will be happy to review the information and confirm compatibility for you. Thank you for choosing WORX!

if i leave it used, why is the battery still self draining?
Hello there! Thank you for your inquiry. Even when the WA3674 lithium‑ion battery is removed from a tool and not actively being used, a small amount of self‑discharge is normal and expected. Inside the battery are electronic components—such as the protection circuit and battery management system—that continue to draw a very small amount of power to monitor voltage, temperature, and cell safety. This means the battery is never truly “off,” and over time it will slowly lose charge on its own. Factors like cold storage temperatures, how long it’s been sitting since the last charge, and whether it was stored fully charged or nearly empty can make the discharge more noticeable. Storing the battery for long periods fully depleted or fully charged can also accelerate the effect. For best results, WORX recommends storing batteries indoors, at room temperature, and at about a 40–60% charge, which helps minimize self‑drain and extends overall battery life. Thank you for choosing WORX!
