Contact Sensor 2nd Gen Draining Battery – serious issue
I have 8 door/window contact sensors 2nd gen installed in May’20. I have gone through 16 CR2032 batteries (8 replacements) in 2 months. Only 3 of the 8 are getting drained every few weeks. I have done a factory reset and re-paired them multiple times. Only 1 of the 3 is the main door, which gets used several times a day. The other 2 are on Windows that rarely get opened. Here are the primary issues I have identified: 1. The issue started in Sep/Oct’20 when these 3 sensors in question started getting polled for battery levels multiple times a day according to event history 2. The remaining 5 sensors do not get polled for battery level, do not have any events related to battery levels, and the batteries remain full 3. The Event History shows erratic battery levels for the 3 sensors in question, LOW, to FULL to OK all in the same day a few hours apart (see attached screen shot). They seem to be getting polled about 10 times a day 4. I spoke to support last week while replacing my second gen keypad for the 2nd time ( both times dead, no power). She said she had no knowledge of any issues with sensors and would have to start with “basic” troubleshooting which my sensors will pass, since they are technically “working”. Since this is obviously an update or software related issue, Is there an option to involve 2nd or 3rd level Ring support without going through 30 minutes of basic trouble-shooting?

I'm having the exact same issue.... I have a door and two window contact sensors within a few feet of each other - same distance from the base station. It's been close to a year since they were all installed. I've not had to replace the batteries in the two window contact sensors yet but it seems that back door sensor just blows through batteries. The front door and garage door sensors (both closer to the base station) don't blow through the batteries as fast either. I was thinking about swapping the back door sensor and front door sensors but when you pull them off their base, the base (stuck to the doors) has a barcode on there too. I mean, I get that the device and the base have no technical reason to match up but I'm guessing that bar code is in case the QR code on the device gets worn to the point it can't be read. I just haven't been willing to risk pulling on the base and perhaps taking some paint off one of the doors. Wanted to do a little research on the problem first, and found your post.

Hi Having same issue. First issue was with sensor failure and the replacement needing batteries on a weekly basis. Now it’s every couple of days. Then keypad totally died after only first recharge. Now two sensors are constantly having issues requiring Battery replacement every other day. Any way to correct this issue?

THi @Errol1. Try leaving a Contact Sensor next to the Base Station with a new battery installed. After a few days, take note of the battery level and see if there is an improvement compared to before. If there is, then distance may be a factor and choosing a new location for your Range Extender or Base Station, may be the best option.

Hi there, @HouTX ! You've reached the Ring Community, a neighbor to neighbor public forum. As this is a public place and not a platform that is monitored by our support team, we can certainly offer helpful suggestions and best steps for troubleshooting, but more advanced support will certainly come from the support team. After reading over the details you've listed efficiently, it certainly seems odd that batteries are fluctuating throughout the day. As you mentioned this being for 2 window and 1 main door Sensor, please ensure these areas are within the temperature controlled home, and not an external or porch like entryway/ windows. Ultimately, I'm recommending to avoid any cold areas, as these Sensors and batteries are rated for indoor use only. Other than environmental placement, distance from the Base Station/ Range Extender is great to consider. I'm sure you've already checked on signal range as a potential factor, so if all is in order as far as connection with the Base Station, the next best step would be to continue the troubleshooting process with our support team. Please give our support team a call at one of the numbers available [here](https://support.ring.com/hc/en-us/articles/213608406). If you are outside of the US, please visit [here ](https://support.ring.com/hc/en-gb/articles/213608406)to see how to contact support. Feel free to let us know how this goes! :)
