I am loaned a prototype of an industrial device (running some Linux with an Android flavor). Each time I turn it off, it loses time, and I need to connect it to some Ethernet network then login by SSH to adjust it. The thing is going on tour for a demo (we make the application,) and our salesman hates it.
Sneaking in, I see this. To me it looks like a 3V battery holder without battery, perhaps because there is apparently not enough clearance around to insert one. I could fix this with wires and hot-melt, but I need to be sure.
Can someone confirm/infirm the intended use of this component?
Note: I would make sure the PCB is not attempting to charge the battery before, and after connecting one. Last thing I want is an explosion inside the thing!
