Does the battery life vary with number of cells; i.e., does run longer on a 6 cell than a 2 cell flashlight?

The battery life is directly proportional to the number of cells. Thus, a 6-cell flashlight would have three times the useful battery life of a 2-cell flashlight with the same type of battery.

I've always used them with two cell flashlights. If the six batteries are in series (- of one battery against the + of the next battery and so on), then you'll increase the voltage but the overall power capacity remains the same. For example, two 1.5 volt batteries in series gives you three volts, but overall should have the same overall power capacity as one 1.5 volt battery. Six would be 6 x 1.5 = 9 volts. Now Having said that, I have recycled nearly dead batteries into flashlights with these LEDs and still get very useful amounts of light for several more months (where the conventional flashlight bulb would have become too dim to use).Hope that helps,Joe I've always used them with two cell flashlights.

I have Nite Ize in both a 2-D cell Maglite as well as a 5-C cell. I really have not used them enough to draw an accurate comparison. I do recall that the 5-C cell, when I used it regularly with a halogen bulb, would eat batteries like crazy. The Nite Ize does seem to give a lot more bang for the buck. Sorry I cannot give you a more definitive answer.

I'm afraid I'm not able to answer that question as I do not have any 2 cell Maglite to compare with. Also, I do not use my Maglite frequently, hence the battery life based on my usage would be rather inaccurate.

Still on my first set of batteries but I found that different led's give different run times. Run times are usually shorter when using the rechargeable 18650 batteries. The longest runtime is with cr123 batteries at a little over 2 hrs.

The battery is pretty long-lasting. I don't know how many hours you can get out of it, but I use it as a modeling light with my speed light flash, and after using it continuously for 3 hours, it still has a good deal of oomph left. No noticeable weakening of the beam. The only thing to remember is that the battery dies quickly when it starts weakening. I think this is the best light I've ever bought -- nice and bright, and plenty long-lasting.

Short answer, no. Long answer: It seems there are multiple variants of this flashlight that are sold. Some have a memory function that at least keeps it in the same mode on each power on. Others have a memory function that is used by turning it on with a long press. I have noticed also that sometimes when turning it on with a normal short click if its been off for a while it turns on in the same mode I turned it off.

I'm not sure. The longest I've left the flashlight on the charger is overnight. It's not good for any battery to be charged constantly.

No. Neither does the battery. I suggest using an 18650 panisonic cell with at least 3000 mAh. Amazon has Orbtronic 3400mAh batteries right now. I'd get two of them per flashlight so that you have a spare to use while charging, and the Nitecore Intellicharger.

I am getting about one and a half hours of continuous use, on high power, out of a 1.5 volt AA battery. You may get more time if you use the 3.7 volt 14500 rechargeable lithium battery. I love the light, it is very bright, brighter than my 2 D cell mag lite. I bought 4 more to give to my family.

It takes a AA battery, however, it doesn't seem to make any difference which MaH you use. I've tried every combination possibe and the best I've had is 1 to 4 hours of light. The avarage is about 2 hours. This is after the experience of 24 lights.

This was a gift for someone else, so it took me some time to find answers and I do apologize for the delay. The flashlight takes triple A batteries and does not specify as to alkaline versus rechargeable, and has a strong illumination. As far as battery life the person I gave it to is not for certain for he only uses it on occasion so his batteries are still going strong. I hope this helps.

It will depend on the charger you use. They last so long that I forgot how long it took. Very bright in the correct flashlight. These are really strong batteries. They are not quick charge. I charged mine overnight with no problems. I am using them in a single cell flashlight. I would purchase the 26650 single cell flashlight with battery and charger for about $25. The 18650 single cell flashlight with charger and battery will be smaller in your pocket for less money, however it is not as bright but totally acceptable.

I've been using mine for about 3 months now, about 40, 5 sec. uses per night at high power. I've had no problems with the switch, and I've not noticed a decrease in brightness over that time (in reply to the question of whether it drains the batteries while off or not; I've never had it on for 5 min. at a time). I love this flashlight.

I use Ultrafire (from China) and Panasonic (from Japan) in a number of flashlights. I have charged all of them at least 10 times each, and can't really tell any difference between them. They all charge within 12 hours, pretty slow, but hold the charge for a long time; I'm talking about many months if you're not using them. Hope this helps.

While all 3 flashlights are almost equal in brightness and battery life, the difference is in the chargers. #75813 takes 10 hrs. to charge & can be charged in a car. #75832 can charge flashlight & spare battery at same time and also in a car. Takes 10hrs. #75816 Can charge flashlight & battery at same time & will charge flashlight in 2 1/2 hrs. (rapid charge) spare battery in 10 hrs. Can also be charged in a car

It comes with two 18650 3000 mah batteries. If you order 18650 (5000 mah) batteries they last longer. I have 10-12 of these flashlights and have never had any problem.

Hi W.J.Two thoughts here. First, I'm not happy with the performance of the battery's life -- seem to work OK for low power items (i.e. wireless mouse), but fall way short of the mark for higher demand items (flashlight) -- I'd guess 10 to 15% of an Alkaline battery life. That said, and in all fairness, it appears there were a number of 'knock-offs' introduced into the selling stream. I'm not sure if mine were part of the counterfit lot.The customer service group at Eneloop aren't the easiest to work with either. I invested about $350 in batteries, cases, charger, sleeves. I wish I could get my money back and move on.Sorry to share my disappointing experience. I hope yours is better. Hi W.J.Two thoughts here.

This flashlight USES 18650 individual cells or 26650 single battery.The price of the battery is not sure, to see whether the brand!

This is a very good flashlight, but for different battery useage i dont know
