XPR6550 stops working

[kg9h]

Finally got the radio I wanted an XPR-6550.
All seems ok but the radio sometimes just turns off.
If I squeeze the radio by slightly pressing the front into the back the radio re-boots and turns on and stays on for hours. But sometimes it turns off.
The contact points seem ok, the battery a factory Impress one.
I heard that the contacts are two sided meaning inside they mate with a pc board. The contacts mating with the battery look perfect.
How hard is it to remove the radio to clean the inside contacts?
Never been inside one of these but did many GP-300's back in the day.
Thoughts?

Clean the contacts with a pencil eraser.

It sounds like the battery is pulling away from the radio chassis. As these radios get older, I have seen that happen. They also have issues where the volume knob wears out the plastic piece that gives you the "click" when you shut it off. I'm not saying that's the issue here but keep that in mind. The volume control is not and expensive part but it is a pain to solder.

Thank you for the reply. Yes the volume pot does not have a "huge detent" but it IS there. Also the radio does seem to have a rubber boot on it, near the contact springs. Maybe the boot is now too high?
Going to try another battery tomorrow.

I have had problems with clone batteries having the same problem. They were bought online and sold as factory brand batteries.

Hmmm good point, I have an IMPRES, seems Motorola throughout. PMNN4069A Li-Ion.
I do agree, the battery seems to be slightly away from the radio.

I have had some in for service with bad volume controls, the switch fails.
