Are these 3.7 batteries different than AA batteries.
829521
yes these are different because have them different voltage and I can use my flash light with this aa batteriesthe zize is different too
829522
yes. the battery is a video camera batt. i didnt find any at the store so i bought them on Amazon. I would stay away from the 501b. mine is defective. get the 502b
829523
Yes, this light can be powered by two cr123 batteries that should be in the photo section of your local big box store. The other option is using the 18650 batteries which are available on amazon and maybe some hobby stores
829524
Yes, they are longer and more thick. Essentially, they are 2 cr123s put together.
829525
Yes they are. They are closer to the size of a C cell battery but twice as long. They are the same type of cell that is in laptop battery packs. If you search 18650 you will find the batteries and chargers here on Amazon for very good prices. All the Ultrafire batteries I have bought work great. This is by far the best of the best when it comes to budget flashlights like these: http://www.amazon.com/UltraFire-WF-502B-XM-LT6-Flashlight-Clip/dp/B006LVBDNU/ref=sr_1_3?s=hi&ie=UTF8&qid=1364293375&sr=1-3&keywords=ultrafire+502b

Regular AA batteries will work and recharge as well as the premium batteries that come with it, but you will not get as many recharges.

Sorry to be so late. They are the size of a standard AA battery, not the short ones sometimes used in solar lights.

I bought this for my son and he said it was "AA" batteries. I bought it for him to use when working on his car and he loves it. Hope this helps.

These are not batteries, but merely casings so you can use a AA battery as a D battery, since you cannot buy rechargeable D batteries. I have not had much luck using them, so I am not a huge fan.

There is no difference to me. These are all small batteries and I don't go out with out 3 fully charged at least! I own a total of 5 batteries. They are so inexpensive, it is not worth worrying about a possible few minutes of power.

Double AA is about 30 % smaller and will not work but these 3.7 v are excellent

Unlikely as the 3.6V battery is slightly larger in size than AA batteries, both in width, and more importantly, in length. It is not a great difference, but most likely enough to make it too large for your flashlight.

No, the batteries I ordered are AA not AAA? My device uses AA, so not sure what your uses. These AAs are the same size as non rechargeable, so. I assume the AAAs will be the same

the batteries are very similar, but not the same. there is a slight difference in actual size

Yes, they are like any cr123a batteries. They seem to hold a very good charge and are worth having. The charger works great too.

No they are not. They are bigger and much stronger. You have to find a flash light that will hold both types of batteries.

I don't know, but I suspect they were older batteries when I received them because they did not last very long

12v A23 batteries. They look like little short AA batteries and I, personally, have only been able to find them online.

Hi Joe,These rechargeable AAA sized batteries are the same size as regular Alkaline AAA batteries.
839467
MY answer was AA, They are not AA just similar in size AA would be 1.5 volts@. These are a little larger and are 3.7 volts @. Sorry for the confusion, Hope this clarifies the issue.

These use a triple A "AAA"... I would not recommend you to get these battery only last for about 3 - 4 hours
