I have 2 Pedators. A few months ago I was having problems with 1 eating through batteries. I sent it in to the service tech here in the US. They said it was because I used the wrong battery. I used a Tek Cell instead of a SafeT battery. The other day I changed batteries in both computers & used the SafeT batteries, now both of them are saying "low battery" only a couple days after changing them. I am going to buy 1 more set of SafeT batteries & see if it may have been a bad battery issue, though I used 4 batteries before I found any that worked. It actually acts as if it is not getting a good contact with the terminals. Anyone else experincing these issues? These issues are getting a little tiresome.
