I'm wondering the same thing here.I put my batteries on the charger last night before heading out his morning for my first time with my xr6 caller today,all pump and ready to see what my new caller will call in today.
Well went to first setup and called for a while then hit mute,Waited 15 min and hit caller again called for about 1 min then it all sudden shut off.Tried to send info again with no repsonse from caller Hmmmmmmmmmm.Finally got up and found my battery light was on,Dang it dead batteries.
"energizer recharagable battires are they good"
These are the batteries in using.It was also the first time using the batteries Should i recharge and will they last longer than a hour of calling or should i look at different batteries???
Any info will help out.Was kinda upset that i had to call it quites early due to dead batteries.
I also notice the caller had a charger spot to plug into to recharge,Can i use any recharger(car) or do i have to use a fox pro recharger and batteries??
Thanks for the help guiys.
