Do not charge

They were delivered quickly. Although they were easy to fit into the video doorball, they are not charging. I have tried swapping them over yet it is still the same. So not very happy as they are quite pricey

Misleading

I got more that I bargained for but the picture is misleading I thought it was coming with a box to place the batteries but I was wrong! I got 3 batteries instead like I said more than I bargained for but still. When it comes to the batteries well what can I say! They do the job
