i was searching on eBay for these to use for my e-cig, well it’s obvious that they were pulled from somewhere, i was wondering what kind of battery packs will contain these? i know laptop pack usually carry 18650. i’m about to order 10 of the 18500 on ebay, but if i can get them for cheaper then why not?
i’m also in the market for a good lithium charger that can charge 18350, 18500 and 18650. i’m on the road alot and need something that is small, good and reliable, one slot is fine, and does not require to use a spacer. i’ve been taking the nitecore i2 with me but that thing is too big. any recommendations will be greatly appreciated!
Xtar XP1 charger is a good choice. Go to their website and check it out.
thanks but on their website, it doesnt seem like it will charge 18650, or did they forgot to put it in the description?
- The XP1 is designed to charge 10440/14500/16340(RCR123A)/18350/18500 3.7V Li-ion batteries or AA/AAA Ni-MH/Ni-Cd batteries.
Sorry about that mistake. My bad. I have a Xtar SP2 charger than can handle 18650 batteries. It work just fine. It is a 2 bay charger. WP2s charger has a cover and can handle 18650 batteries also.
no big deal 
, i like the miller ml102, wish it would have the extendable spring like many other charger without requiring a spacer. that would just be perfect for me.
Compatible with: Li-ion: 26650, 22650, 18650, 17670, 18490, 17500, 17335, 16340

17500 and 18500 li-ion cells are commonly found inside DSLR battery packs.
Everything you need to know about the VP1 charger is here. The VP1 charges an 18650 with NO problems whatsoever. In fact, the VP1 also charges Sanyo 18500 cells without any problems as well. 
Review of Charger Xtar VP1
I bought these 18500 cells. These are excellent! http://www.fasttech.com/products/1420/10004184/1315401-authentic-sanyo-ur18500fk-18500-1700mah-37v-rechar
One of the 1st Li-Ion batteries I bought was an 18500, and I was told that they’re used for solar-powered lights at the time.
