Just make sure the regulator in the flashlight can deal with them, they give a little higher voltage, some are up to 4,7V.
Length and width can also vary a little.

On the backside, Li batts can give you a nasty fire...



I am not opposed to rechargeable battery's, but I hate products that work only on rechargeable battery's. I like knowing I can zip over to the store at say 8pm and be able to head out on my hike as soon as I am done...

Alas all these new battery sizes are so new to me, I nearly blew it on this purchase being my hatred for rechargeable only (the flashlight runs on 2 18650s). Frankly; as much as I know they are awesome, if a battery isn't labeled using the first 4 letters of the alphabet or start with a 9, I am lost lol! Hence, when I ordered the Barracuda, I clearly had no idea that 18659s only came in rechargeable format. Sigh.

Of course, the flashlight will also take 4 - 123s as well, so I am covered lol. Whew. I really need to learn more about these new formats. I am sure I'll get more out of my flashlight by doing so.

I bought a charger and two protected 18659s battery's (RediLast 3400mAH 18650 Protected) for my new flashlight. I figure they'll do 99% of the "heavy" work, and a 9 pack of 123's to back-up the 18650s.

I hope I didn't blow it as those two battery's and the charger weren't exactly free! They were dear enough to keep a man in smokes for a good week or two lol... sigh.

Hey how do you make a fire with the Li batts?
