explain this

I use an armband radio while running. The battery
compartment lid is damaged, I repaired it using a
sophisticated high tech rubber band technique.

Occasionally, the lid connection is visibly loose,
yet the battery indicator shows high capacity. But
when I adjust the elastic to tighten it, the display
will drop to a lower capacity. Similarly, if I
thumb press the lid tight, it also shows low capacity.

huh?

How reliable are these battery indicators, anyhow?
They're ubiquitous, so they must be very cheap.

Lid connection? The lid has a connection to it?

I don't think I've ever seen one. Is it on the battery, or on the
radio, or what?
