3.7 batteries are the way to go.
August 15, 2020
If you don't own an led flashlight that uses these types of batteries you need to look into it. I have several of them and the small size of these flashlights are soooo much better than the old style type of bulky flashlight that I grew up with... I'm 65 by the way.... lol. These new style of led flashlights that these batteries power, have so many advantages over the way flashlights were made in the days of old.... Yep.... I'm a dinosaur but you are living in my past and living in dino land too if you don't get with the program here. The voltage of these batteries is 3.7 volts and you need to be careful not to put any batteries that have this voltage in the types of devices you have that they may fit in... but don't support the higher voltage of these... you will not be happy with the result of doing that. Make sure of the voltage requirements of anything you put these in before doing so. These batteries are about the same size as a AA batteries and will fit a lot of those types of devices so be careful with them .... also be careful to store them in a different area than those types of batteries so you and others won't make the mistake of getting this wrong and ruining your devices. Also, get a smart charger that will charge these up right for you... and the flashlight that these fit in.... and have a few of these batteries charged and ready to go and you will see why I am a fan of them. The light that these little gems emit is awesome and although these batteries seem to be a bit high priced... that is true... when you see the benefits of getting with the times... you will understand why I am hooked on them. Don't cheap out and keep buying batteries that you throw away after they lose their charge in your old style flashlight.... Get with the times people... you will be happy you did.

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.)
ProsThe 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.
ConsThis 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.

Does this battery come charged on arrival? If not, what percentage charge is it? Also, assuming a completely dead battery, how long does it take to charge? Thanks!
1 Answer
Itís a Li-Ion battery, so it will come with about 30-40% charge but should be fully charged before use. Charging should take roughly about 2 hours.
