TriSquare Battery Life

I can have both charged the same and use them,after a few hours of use,turning on and off,one talkie was slap dead and the other still showing 3 bars.
I think there is some thing wrong it.Very disappointed in their performance.
I may go exchange them next week.

Also,when I put rechargeables in them yesterday the battery meter only shows 2 bars.And I just charged them Friday.
