can I use this 26650 battery where I have been using a 18650 battery instead????

Yes as long as you take out the plastic sleeves for the 18650 if your light has them
2007793
No. The 26650 is a somewhat larger battery and will not always fit every device a 18650 does.
2007794
No. While the 26650 is the same length as the 18650 it is considerably larger in diameter. However, they're both 3.7v and if size were not an issue one should be able to use either size.

NO! I don't know what those other two reviewers got, but the ones I received does not allow the 18650 batteries to go in. SonOfUncleSam hit it right on the nose.

Both work. You can put either 2 or 3 18650 batteries in it. If you want to use 2 batteries, you can just take the last pipe on the flashlight away. The last pipe on the flashlight is designed to be taken away. But I really do not think 2-18650-battery can support the flashlight for long time. 3-26650-battery can support the flashlight less then two hours. When you use the flashlight indoor, it will work even shorter because it will become very hot. Also,There are inner pipes which can be taken our and which specially design for 18650 batteries. Those inner pipes can easily be taken out. You must put those inner pipe in to fit 18650 batteries. Actually, there is a video about 8500lm flashlight on YouTube, you can just search " 8500lm flashlight". I really do not know how many watts it has. I guess it may have about 50 watts. I know the HID headlights in cars normally have about 55 watts with 12v storage batteries. This flashlight has 11.1v.

I use them in my mod, they are the longest lasting batteries I own. just make sure your mod excepts 18650's.

Model number 18650 / 2 600 Ah Li - ion rechargeable battery. Best to go to a batteries plus to ensure proper fit.

Vivek, you can use this battery but please note that you will have to reuse and hardware you currently have as we sell only the battery itself. It has the same size and performs identically.

You can but it would be stupid to do so. I use 1 protected 18650 and it works great. Extremely bright light. I have had mine for two years and use it for everything. Best light I have ever had

The 18650 battery will work. Its designed to use 18650. However, not sure if quality 18650 batteries come in 4000mah.

No, you cannot use these in place of an 18660. The number denotes the size of the battery. The first 2 numbers are the diameter and the next 2 are the length. An 18650 is 18mm in diameter and 65mm long. A 26650 is 26mm in diameter and 65mm long.

The AA or AAA batteries are of a different size and shape and the voltage is different. I found that you can order conversion kits, but the reviews on them are not good. The 18650 battery holds a charge for a long time and I find it quite convenient. I keep a second battery charged at all times in the event I need to replace.

it's hard to say most use 18650 batteries but without the model of your flashlight it's hard to say. look here for your model and it will tell you what battery it uses.http://www.lightmalls.com/uniquefire-flashlights

I have the same light and the three (3) 26650 batteries and they fit fine. The 18650 batteries are the same length as the 26650, the only differences are the mAH rating and the 26650 are twice the size in diameter. Your flashlight should consist of four (4) body pieces which are the switch cap, two (2) body pieces, and the light assembly. If the light won't screw all the together I would check the switch cap and the for something that may have gotten stuck inside.

26650 batteries are larger than CR123 batteries. CR123 batteries are about the size of 16340 batteries. You can find a list of battery sizes at Wikipedia. Search for battery sizes.

the 18650 will not fit this flashlight. i own both this flashlight and the slightly larger ones that use the 18650 lithium rechargables. the smaller light uses 14500's or AA batteries...they are the same size. 14500's are highly recommended as they put out a lot more light and are 3.6v instead of the AA's which are 1.5v

no, you can do the opposite with an adapter 18650 with adapter will replace a 26650

google if they can be interchanged. You probably can. However, I don't know the answer for sure, but would strongly suggest you use the battery recommended for your item.
