    I have used these regularly in a P7D LED flashlight. They have produced decent run times and do not heat up etc. like some cheaper batteries. The rating of 2600maH seems fairly accurate.
    Cons:
    None that I can think of except that the 2600maH may be slightly overrated. Very tight fit in my .sku1251 Ultrafire charger(pro...
