I was getting low battery notifications after just a few days of installing the batteries. It seemed the battery contact was loose so i added a piece of foil to one side (see pic- bottom battery) to tighten/increase the pressure on the battery contacts. That seemed to fix the issue temporarily. The problem is if someone closes the door hard it seems to get loose and then the low battery/depleted error comes on and then I have to manually open the unit and adjust the battery contact again. Is there another known fix for this?
