Charger is kinda big, my other Worx charger is a tiny fraction of the size. It seems to charge the batteries in about 3/4 the amount of time as my other charger. The batteries are well-built with heavy plastic casing and plug in easily to my Worx tools. They work as they should and are a good value replacement compared to the price of the original brand. The extra charger is really handy. A good price and value for the money for what it is.

The charger is rated to supply 2A to the battery. I measured the chargers power draw from the 120V AC outlet at 42 Watts. I don’t know the efficiency of this charger, but with 42W in, there should be somewhere between 1 and 2 Amps flowing to the battery. The battery voltage tops out at 20.7V when the charger stops charging. All good.I ran a fixed 2A discharge capacity test on these batteries using my West Mountain Radio Computerized Battery Analyzer and got 1.91AH.I knew when I ordered this package that the batteries would not be 3.5AH. These are thin, 5 cell, batteries and I rarely see cells higher than 2AH in these after market batteries. I’m actually happy these are 2AH and not 1.5AH.Even though I knew these would not be 3.5AH, I still wanted this package because I like these smaller, lighter batteries. Most of my projects now are simple and short so my big batteries just sit in storage.And the current price of $46 for 2 batteries and a charger is a good deal.

They work in my Worx 40v lawnmower, which came standard with 4AH batteries. However, these are rated 3.5AH, and they do not have the reserve power compared to the oem batteries, which I should have expected, and last about half as long when mowing, which I didn't expect.If I wanted to replace these batteries, I would either stick with Worx brand batteries or get other replacement batteries rated at 5AH or 6AH.
