Laser Rangefinder Battery Story
I was on the course today and on the back 9 my Bushnell V4 went completely dead. One fairway reading it worked fine, the next hole nothing. I went home and put my meter on it (CR-2 battery) and it read 3.58 volts for a 3 volt battery. I went to the store and purchased a new CR2, put it in and everything works fine now. So possibly lithium batteries can still hold acceptable voltage but loose their ability to provide current to the device. Electrical pros feel free to chime in. So even if you think your laser died try changing out the battery first.
