Wyze Sense Contact battery lasting 1 week

Hi everyone - i have several wyze sense contacts mounted on doors. One specific one is going through a battery in less than a week - I change the battery, and then about 5 days later get a low battery indication. Check with the meter, and the battery voltage is indeed down to 2.7 ish volts. The other contacts seem to be lasting at least 5 months. I have been using the same replacement batteries in all contacts, but only having issues with this one. Any ideas? Thanks.
