has anyone else on here ever gotten the message "overcharged" when they turn on their E-Trac for the first time after charging their stock battery ? this happened to me the other day when I took the battery off the charger, stuck it in the ETrac, went to my next door neighbor's house to hunt and when I turned it on, it said overcharged (or maybe just "overcharge", can't remember) on the display, made a musical note and immediately turned itself off... It did this about 5 times in a row before it finally powered up the way it is supposed to... has this ever happened to anyone else ? I have heard that the RNB batteries are a higher voltage than the stock Minelab battery too and I hear that they work great.... how in the heck could I have overcharged the stock battery ???
