Hey yotehunter that is very interesting. I have a couple flashlights that use lithium batteries. You re right. They cost more but perform much better. Batteries are weird though. It depends a lot on what you are powering it seems. For example, the Foxpro. I might get a day or two of hard calling with ni-cads. When it goes dead, it is all of a sudden, bam, it's dead. Now with alks I have only got to experience one set go dead in the FP so far. It was a used set out of my flashlight. They started to fade on high volume. I reduced the volume and was able to finish the stand. I really didn't notice a performance change till that time. The gradual loss of voltage at the end is more desirable than the sudden complete loss of power during a stand. Plus 4 alks for a whole season of calling is pretty cheap. Lithium's are $7.50 a battery where I live but I'm sure they can be found much cheaper elsewhere.
Now in a flashlight I much prefer the lithium batteries. They retain a crisp white light till the end and clearly outperform the alks.
You seem to really now your stuff about batteries yote. Appreciate the great info you are sharing. What do you do for a living again? Not trying to pry, just kind of interesting. /ubbthreads/images/graemlins/smile.gif
