If you put in a 14650 battery it will last longer than the 14500. I own a 18650 model and it will last all day if you use a 3000 mah battery but will also last a long time with the 2200 mah battery. Hope this helps.
Do you know how well these paticuler batteries work?
They're Ultra Fire TRC 18650 3800 mAh
3.7v li-ion Low discharge rate, No memory effect
Short-circuit and over current Protection.

It seems like to high of mah for this paticuler battery. Anyone know?
