[TenTec] O2 Question

[Kim Elmore]

The past couple of times I've been away from the rig for a few days, 
when I turn it on I see that it no longer completely retains its last 
state (band stack, rx BW settings, audio settings, etc.). Is this an 
early sign that I need to replace the backup battery in the radio? I 
know that it's a SnapHat battery and I've replaced it before, but don't 
recall how long ago. How long should it last?
