It comes with a battery but is not a standard battery you will have to hunt for a replacement for it

We have a doorbell but its really strange one at that because it just beeps once and thats it nothing else

The door bell is easy to set up and you can place anywhere as this is one of the benefits of having it wireless and on a another note if you move you can take it will you just in case the next place doesnt have a door bell at all

Goes rather far in distance it is 280m900 feel long in range thats actually a good distance on any kind of door bell lights up with a led blue light when the door bell has been ranged

Not able to judge the listed distance it covers

Probably will not purchase this model again but would recommend for someone that needs a reasonably priced doorbell
