Fernando F. Lebron: Charged up fast and held a good charge for 90 minutes.

Mrguy: 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.

Chuck: 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...

Mark T.: Plugged the 4.0 Ah battery onto my WORX leaf blower and it seems that it auto turn off when I switch to high speed.

Seems to work well only at low speed.

This is unlike my original WORX 20V, 2.0 Ah battery that works well for both low and high speed.

Terry: This Powershare battery charges in about an hour and runs my Landroid L WR153 robot lawnmower for 2 hours. The battery can take up to 10 hours to charge on standard charger (WA3742), or two hours with a quick charger (WA3868). I bought the WORX WA3875 20V Li-Ion Dual Port 2 Hour Quick Charger on Amazon so I always have a spare battery to charge as it takes about 2 hours to charge. They also sell a 2.0Ah (WA3575) and a 6 .0 Ah (WA3671). All of these batteries will work in your Worx product if it is 20V and will fit as the 6.0 Ah is taller. The 6.0Ah will last 3 times longer than the 2.0Ah. The 6.0Ah is often sold out and harder to get.
My Landroid will fit the 6.0Ah tall battery, but not all Landroid's will fit the 6.0Ah battery.
For the $30 more, I would buy the larger battery for the Landroid mower, but for a tool you hold all day the battery may be heavy. The 4.0Ah 20V battery (WA3578) weighs about 1.4lbs.

Recommended for use with WA3742 20V charger or WA3868 20V quick charger.

Welsh Dragon: These batteries work with the WORX powershare tools. Easy enough to use and the useful feature is that there is power charge indicator on the battery itself. My only concern is the battery life, but this depends on usage.

Kris B: Bought this battery as a spare battery to power my WORX Pressure Washer. Charges up quickly on regular WORX charger with lots of power and necessary extra capacity for longer jobs like cleaning eaves and sidings for cleaning and prep work. As a Painter, I use my WORX Pressure washer to apply cleaning solutions followed by an electric (or gas) Pressure Washer for the wash and rinse. Great combo! Good Results.
