As for battery life, I purchased mine used from a PM member and it came without instruction booklet but w/batteries installed. Used it for quite a while and finally batteries failed so put in a couple of rechargeable batteries. They pooped out same day installed. Limped through the rest of the hunt w/more rechargeables with same results so figured it needed NiCads or lithium. Purchased some lithiums and they didn't last very long either. Finally looked at a mojo add online and noticed the small print said AA batteries (4) not included.
Once I replaced the other two batteries (that were hidden from my old eyeballs) battery life improved immensely. lol
