I'm confused about UltraFire 14500 AA sized 3.6V Li-Ion Rechargeable Battery 900mAh CR 14500 Lithium Ion: What ARE these batteries good for if they are not good for replacing regular AA batteries?

Those batteries can replace regular aa in certain items only.They give more power than the regular aa but have to be used only in compatible items.For example they are great in this flashlight http://www.amazon.com/BBQbuy-300lm-Flashlight-Torch-Adjustable/dp/B006E0QAFY/ref=sr_1_2?ie=UTF8&qid=1355173097&sr=8-2&keywords=mini+flashlight

The battery is a Lithium Ion Battery, and I actually think the lifetime is pretty anemic (is only 900mAh if I remember correctly). Still it's good for several hundred shots (fewer if you use a lot of flash), but if you are on a long vacation, that is not enough. I'd recommend getting a backup battery, preferably one with a higher capacity (e.g. 1100 mAh). Also, when it gives the "battery warning" you probably have less than 10-20 shots left before the battery dies.

The number in the battery code is actually the dimensions as well.. 18650 means it is roughly 18mm thick and 65mm long... but this is not exact dimensions.. the actual sizes is more like 18.6mm by 65.2mm.. and if the battery includes a protection circuit the length can be up to 68mm.A 14500 battery would be 14mm X 50mm which is the same size as an AA battery.

The 18650 batterie are larger that the 14500, and need a specific charger for them. They are about half-way between a AA and C size battery, the 14500 is an AA size battery.

AA batteries will not work with this light. A single 18650 battery is what is recommended preferably a Panasonic or Tenergy 18650....most of the 18650 batteries sold are junk like ulrafire and trustfire.This is the one you need for your AA batteries--> UltraFire 7w 300lm Mini Cree Led Flashlight Torch Adjustable Focus Zoom Light Lamp

Are you referring to the AA or the AAA? I don't know too many AA batteries that only have 900mAh capacity. Even the first AA NiMH batteries i got were at 1600mAh. Double check that you are getting the correct size batteries.

www.amazon.com/Ultrafire-Lumens-Zoomable-26650-Flashlight/dp/B0092Q1N7W is a great use of the batteries. You will need something that takes the 26650 battery and a charger for the batteries to use them.

No. They are 18650 batteries. Probably removed from a used up laptop battery.Ultrafire batteries are crap. You might get lucky, and get a good one, probably not.

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

That's one downside here. AA's are too small. An alternate is the C123. That will be a pricey alternative because the XMLT6 will gobble them up. Go with the rechargeables.

I have tested AA and AAA alkaline and rechargeable up to 2500 ma in rechargeable. I have also used it with the CR123 3v lithium that my flashlights use with very good success. I have not tested any other batteries so far. My AA rechargeable batteries are the nickel metal hydride type. I have not tested the older nicad type rechargeable.

I have several 18650 batteries. They are all the red UltraFire batteries, but I'm sure they would be the same size as yours. The single red UltraFire 18650 battery is too long and too narrow for this flashlight. At least the "AAA" batteries it takes are easy to find.
