Hi all, I have a question about the e-trac battery with the x-1 probe attached. I was told by my dealer that the e-trac battery takes 12 hours to fully charge and should last around 20 hours worst case scenario with the x-1 probe. Does this sound right? I do not seem to be getting that amount of time out of mine. I am charging mine as we speak for at least 12 hours and I am going to keep track of the time I get out of it. It is still under warranty til August. Thanks all and HH.
