I have an electric sprayer for cleaning solution at my job. I'd say the sprayer is in my hand for at least an hour a day, on and off. It's powered by one of these 16850 batteries at all time and is constantly being turned on and off throughout the whole day. A single charged battery can last me over two weeks, easily. I'm impressed at the capacity and how quickly these charge. I might even buy myself another sprayer for the other cleaning solution I use, just because this setup has been so reliable.

Works perfectly, lots of savings on buying batteries!

Battery charger works quite well. The Red indicator turns Green when battery is charged. Fully charged battery works quite well.The only reason I took one star away is because the battery does not remain seated against the Positive terminal. I had to use a rubber band wrapped around the battery and charger to keep it in place. Masking tape would also work.I would recommend this to a family member or friend.

Good fast charger for the battery.Works perfect upon opening the box

Awesome product.

The battery is ok but charger is so weak that comes with the broken charger.Can not use the charger but I just needed the batteries so I don't mine.

Cheaply made. Does not hold the battery in tight enough for charging. Had to use rubber bands to hold the battery in for adequate charge. Don't recommend. Save your money.

Excellent. Exactly wat was needing
