How long should my DC 30's operate on a full charge?
I went hunting the other night at 7:30 returned at 11:30. One collar showed 1/2 charge, the other 3 showed 3/4 charge. I left them on purposely in the truck. I returned around 8:00 the next morning to check them, they were all "off". Is this a realistic operation time? All collars are programmed at 5 second update.

John,

I'm no expert on those time bombs waiting to give problems. But that sounds like about the right amount of time at five seconds.

Take care, Willie

Sounds like your batteries are getting weak unless it was pretty cold out.

Mine on 10sec update drop 1 battery bar in about12hrs so i say you have weak batterys
