Ring outdoor siren does'nt recognise rechargeable battery

I originally set up my outdoor siren with the D-batteries that came with the package, having only finding out after installation that the ring siren requires another power source to enable the dusk/dawn feature I purchased the ring rechargeable battery. After fully charging the battery I installed the battery in my Siren only to find the battery has not been recognised as being installed…any help would be appreciated thanks

Hi @daniel7512. When charging the Quick Release Battery, you will see a solid green LED light to indicate that it has been fully charged. When you insert the fully-charged Quick Release Battery, make sure to start with the pin side. If you are still unable to set up the Dusk to Dawn feature, try removing the Outdoor Siren and completing a new setup in the Ring app.
