These were the right batteries for my video doorbell. The only problem I had was the center battery position would not fit snugly. A little tweeking and I got it to work finally. Always great reliable products and great service.

There are many brands of 18650 Lithium Ion online. From my previous experience, not all Lithium Ion batteries are same. Some can be really bad. This brand is a very good one. I've used these batteries to replace my power tool batteries. They provide enough power and last quite long.
