Small Flashlight use creates major heat....I went back to standard AA
December 10, 2014
This battery pushes a major amount of power, and for the Nitecore (AA x 1) SENS flashlight I purchased the light got very hot. I ended up putting standard AA batteries in the light as I did not want to deal with the major heat generated or have my other Service technicians dealing with this and the charger and such. For extended run times for hikes, camping, or such, this extra power would surely give you enhanced light/burn time, but for the everyday pocket flashlight use for most people, the AA batteries would probably be fine.
I am sure every use has its own specific battery needs and power draw, so the battery may be great for other uses, but for the small Nitecore SENS flashlight, I don't see the beneficial value in having all this available power and heat. (When used on high for more than a few minutes.)
Pros:The battery can push a lot of power, so if you have a high drain power need, it will provide power enough to do the job.
The battery does project more lighting power in AA flashlights which are capable of handling this amount of power, but for the Nitecore SENS light, I like the low power setting to be a little more dim than it was with the 14500, so the extra power capability has both positive and negative usage impact.
Cons:This battery can generate a major amount of heat in a small AA x 1 battery, pocket sized flashlight, so consider your use to see if this battery or standard AA batteries can meet the need.
