I want to buy an 18650 battery to go with this, but they seem to come in different lengths depending on their mAh. What's the right mAh?

I don't know the right mAh, but I happen to have an 18650, and it's been working well. Mine is 3800 mAh, 3.7 V Li-ion. I'm not an expert on this, please try it on your own risk.

Unfortunately, the 18650 rechargeable battery will not fit in the flashlights. Mine just arrived around a half an hour ago, and tested them with the 18650, which sticks out from the base of the flashlight about a quarter of an inch. I'm not sure if this post was referring to an older model, but it doesn't fit the current.

I ordered a 6 cell ion lithium battery. My part number was not listed for any of the batteries, so I ordered the one I thought met the specifications of my Dell battery. I was advised by others when I had asked question who said not to go bigger (# cells) than what I had because it wouldn't fit. I would definitely buy Anker brand. When I researched batteries Anker really seemed to be top of the line. Very glad I went that way. Hope this has been some help to you. Good Luck.

The answer is in the name of the battery. It's a 18650, which means it's 18mm x 65mm.

I purchased 3.7V 18650 3000mah Rechargeable Batterys. They seem to work well. I've used them for about a year so far.

I had to Google 18650 battery to see how big it was but it looks like it's about the same diameter as a cr123 and about 1.5x the length so I would think it would fit one 18650

As long as the voltage is the same you are just fine. The higher the mAh number the longer it will hold a charge.I always try to find replacement rechargeable batteries with a high mAh rating. mAh stands for milliampere hours.

Should be the exact same battery. The higher the mah, the longer the battery will be.

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

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

No. A 18650 battery is much larger. This one accepts a 14500 battery which is explained in the following article; http://lightsngear.com/what-you-need-to-know-about-the-14500-lithium-battery/

18650 is 4mm thicker, and 15mm longer than AA according to what I read. There does not appear to be any extra space in the flashlight battery compartment. I would say no. The 18650 will not fit.

I have found that the 18650 3000mAH batteries work very well with it. You can get the inexpensive charger andd use them over and over again or charge up an extra set for when the ones in the flashlight drain down. The specific brand I use is UltraFire batteries.

Can't be. An 18650 is WAY bigger than a CR123A and has 2-3,000 mAh. In a word...unpossible.

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.

Any charger that will fit the 18650 batteries. Amazon has some that are around 6 bucks and I use it. It's generic but works great.

I believe the 18650 is the same thing as a AA or AAA battery. If so, then yes it will. Sorry, I was wrong. It may be the same size as aaa or aa but LI-ion batteries need thier own kind of charger. I was thinking that this charger was Li-ion, but it is NiMH. It probably will not work.
