  Hey @RustyE! The battery used in Contact Sensors and Motion Detectors is a CR123A battery, which can be found on Amazon.com. That being said, these batteries can last up to 3 years depending on usage. I recommend visiting the specific sensor in your Alarm devices list to see what battery level it is reporting. In the top right of the device page in the app, you should see a battery icon where green is good, yellow is low, and red is needing replaced. If you do need to replace a battery, check out our [help center article about replacing the battery in your Alarm devices](https://support.ring.com/hc/en-us/articles/360000215383-Replacing-the-Battery-on-Your-Alarm-Devices). I hope this helps! :)

  I have 11 door/window sensors in my home, one has gone through three batteries since my installation in September. This is the only one that I've needed to replace. All the other sensors are working fine and haven't needed a replacement. Could it be something wrong with that particular window sensor?

  No, not yet. I have the type 1's and it said to put a cr123a lithium battery into it. I bought the battery...we'll see if it lasts. Did you replace yours? If so, with what?

  RIng sent me a replacement window sensor and I sent the defective one back. I haven't had a problem with it since last year. For some reason it kept draining the battery in two weeks without opeining or closing that particular wiondow.

  I got a same problem. I have 5 sensors, 4 for door and 1 for windows. For whatever the reason Window sensor battery is draining fast. I read the forum saying alot of usage will drain but the funny thing is this window is never open and there is no activity yet this sensor sucks up the battery most. The other 4 sensors are still at 99% and works fine. Do I have defective sensor? Should I contact ring support?

  I too have a window sensor that keeps draining battery life. But oddly, it says battery ok then battery full then repeat for a few days until it says battery low then battery ok and so on. I just replaced the battery a few days ago and doing the same thing all over again.

  Hi @Dustibanana. Try leaving your Contact Sensor next to the Base Station for a few days. If the battery doesn't drain quickly like it has been previously, then this will let you know that distance is more than likely the issue. If it does drain quickly next to the Base Station, you'll need to contact our support team.

  I have an issue with a ring second gen door contact sensor. I have to replace the battery every 2 weeks and do not use the door often. Range to extender and base station are good. I’m going to call support because I know it’s a defective sensor. I’ll post the outcome of the situation after I speak with someone and see if we can add some advice/help with this issue.
