I'm thinking of using a coin cell battery retainer on an upcoming project. The target application will be in a medium-to-high vibration environment with around 1-2 years between battery changes. Unit will be in a dust-tight enclosure.
The retainer in question is MPD BK-5033. I'm concerned with maintaining good battery contact, as it powers a uC storing values in RAM. The application is very, very low power, and there are some capacitors to prevent millisecond length glitches. What bothers me is the idea of creating a pad on the PCB that has to maintain contact with the battery terminal.
If anyone has experience with this type of battery holder, I would love to hear any pointers.
