Doorbell 2 install

I want to connect this to my original doorbel, to be able to use its chime, it is battery operated and not mains electricity, is this OK, will it still work,

I intend to use the doorbell with its own battery,

Hey @Coptleigh. You can most definitely connect your Ring Video Doorbell 2 to your current doorbell’s setup. Please check out our Ring Help Center Article here for more information on how to achieve this. Hope this helps!
