Hi @Kenny326. I’d be happy to try and answer all of your questions. First, you can check out our Help Center Article here, which goes over all of the differences between the Gen 1 and Gen 2 Ring Alarm system. All Ring Alarm security devices are compatible with every Base Station. You can mix and match 1st and 2nd generation Ring Alarm Contact Sensors, Motion Detectors, Range Extenders, Keypads and third-party devices with any Ring Alarm Base Station.
As for the Range Extender, the 2nd gen is designed to be easier to use with a new button and indicator light on the front. Should you run into any concerns with the Range Extender regarding the battery, you’d want to contact our support team so they can take a look at the warranty and determine the best course of action. You can give our support team a call at one of the numbers available here. We’re taking additional steps to protect our team and help reduce the spread of COVID-19, so this has resulted in longer than normal wait times. If you are outside of the US, please read our response to COVID-19 here to see how to contact support.
