Surefire batteries offer extended life
The 123 Surefire Lithium batteries have a long lasting life and really perform in my Surefire flashlight.  I use the light to track deer and the batteries ensure that I can stay on the trail longer if necessary.  I also found the price via Amazon for these batteries to be very favorable to the consumer as opposed to buying them at a retail location.  They also arrived very fast.
