Description

Providing double the runtime of our standard 2.0 Ah Power Share battery, this 4.0 Ah version is for bigger yards or tougher jobs. When you need twice the juice to get that project done, this is the battery for you. It powers everything on the platform: Saws and leaf blowers, drill/drivers and trimmers, lawnmowers and nail guns. So, theoretically, you could power your entire Worx Power Share collection on just this one battery. Think of the money you’ll save. Max Lithium-Ion technology makes for a lighter, longer-lasting battery than other designs. They won’t wane or drain, and you’ll get a full charge every time you fill it back up on the charger. Previous versions of rechargeable batteries would suffer from the dreaded memory effect, which would prevent them from fully recharging as they got older. Not these. You’ll get a full charge all throughout its lifetime. This battery is intended to be used with the following chargers (not included): WA3742, WA3868 quick charger, WA3875 dual-port charger, WA3878 dual-port quick charger. Whether you’ve been on the Power Share platform for years, or you’re just beginning your collection, you’ll save money and be free from the cord. Stop paying at the pump, or getting snagged on trees, and enjoy the cordless power tool lifestyle.

    • Used with a string trimmer, and now I can actually get the whole garden done
Style: Power Share 20V 4.0Ah Pattern: Battery
I have a Worx string trimmer that came with a 2AH battery. That original battery always ran out about 80% through using it. This 4AH battery easily lasts the entire job, and I still have the 2AH one in reserve. It seems to be a pretty well-made pack, and the cells inside are hopefully quality and long-lifetime. It was pretty expensive, but that's the way these power tool companies work now. Cheap tools, expensive batteries. SPECIAL NOTE: I tried a cheap "6AH" Chinese knock-off no-name battery before I bought the name-brand one, and it wouldn't even charge with the official charger. When I took it apart and tested the 18650 batteries inside the knockoff Chinese battery, they corresponded to an overall battery pack that had about 2.5AH (not 6AH), so even if it had worked, it wouldn't have been worth the price, as it was about the price of a 2 or 3AH battery. Also, the reason it wouldn't charge was that the battery management system board was dead on arrival. Long story short, I do NOT recommend buying the knockoffs. They overstate their capacity, they use mediocre cells, the electronics in them are cheap and unreliable, and they are probably dangerous as a result. If you are strapped for cash, you might as well just buy the name-brand in a "lower" capacity. ... show more

    • Battery has power when you need it!

It's easy to charge, and easy to use. The battery holds plenty of power for the vacume.

    • Depends on what you use it for.
Style: Power Share 20V 4.0Ah Pattern: Battery
It works great for my Worx drill, shop light, sander. Anything you use constantly without stopping you should expect shorter life expectancy, i.e. blowers, mowers, etc. if it applies.

    • Honestly surprised - 1yr review
Style: Power Share 20V 4.0Ah Pattern: Battery
With all the junk that's out there in the world I didn't have high hopes for this battery. I bought it as an xmas gift last December and has been used all summer long. It really does last a long time and no detectable loss in performance. Slots in the Worx tools nicely, positive click when its seated. Really cant find anything different about it when compared to the worx branded batteries. ... show more

    • Chock full of electrons!
Style: Power Share 20V 4.0Ah Pattern: Battery
And ready to store more for your convenient use. I have about decided that this battery is about all the work I want to do with a WORX tool - in this case a chainsaw. By the time this battery gives out, so am I and it's time to quit anyway. Since they have a variety of battery capacities, base the size you buy (2A, 4A, 6A, etc.) on your age and the amount of time you want to work. That way, when you flop out in the easy chair after a round of yardwork you can tell the wife "I worked until the battery ran out.... it's recharging!" and you can recharge with cold adult beverage with a true metric to judge your work by. Inescapable logic! Just don't let you wife be ordering any extra batteries or that high speed charger thingy they sell. If you convert all your yard equipment over to WORX you can even use it as a bargaining tool! "Honey, I'm gona weedeat the yard until the battery runs out, then I have to call it....." You can tell your buddies at 1:00pm, "Hey, I gotta weedeat the yard first and the battery lasts about 45 minutes, so I can make that 2:00 pm tee time!" Thanx Worx! ... show more
