Hi @Veg! The Ring Alarm Retrofit Kit features it’s own internal battery backup. Find out more about this in our Retrofit Kit Manual. If you are experiencing power concerns or still have questions about this, feel free to reach out to our support team, or check back here in case neighbors shared their recommendations. I hope this helps!

I used a “battery eliminator” and it’s plugged into a UPS so no need to replace or recharge batteries and the UPS provides power in event of a power failure.

Battery Eliminator - CR123A, 1 Cell Battery Replacement- AC Source, 3VDC
