Question: Do these come with a plastic case?
Document: Batteries work great, last long, love that they come with a clear plastic case, so you can hold your spare batteries in the case. As always Amazon delivery was quick and packaging solid!
These batteries are all the rage in the high performance flashlights forums. So I got some. They are good and do last a long time. I chose to buy them through Amazon. In case I had any customer issue problems.
If you think 1/8 inch longer batteries is going to be a problem for you, you might want to think about something else. (assuming you're comparing to the super cheap (SureFire?) batteries that come with headlamps &#60;$20.Spend the money - you will love having batteries that really function! !
Though they're new, if current perfomance is an indicator of things to come, then I chose well. I'm using three of them to power a high end super thrower hand held spotlight, 3800 lumens that can illiuminate objects up to 1000 yards away. As you can imagine this puts enormous strain on the batteries, so much so that eachomr  has s built in protective circuitry, built by Seiko, to prevent any number of things that could possibly go boom in the night.
works good in one of my mechanical caravela mod  with the smallest pin in the top cap only thats what I purchased them for vapor mod I've been using flat top batteries work also
the item is as described it look and feels quality. I'm using them with my 8000lm flash light and boy it flashes.
performs as advertised. I am a vaporThe batteries perform as advertised. I use them in vapor equipment. I would reccomnd to a friend
a truly trustworthy company in its postings and product. As many have attested to , threw usage and daily experiences this battery is worth the high trust worthy stamp of approval. safe, reliable and dollar for dollar a valued purchase. thanks for the high integrity. Keep up the superior STANDARDS
Wow...these are great batteries. They hold a charge for weeks even through moderate to heavy use with my Nitecore P16 flashlight. They are worth the price! !
What a disappointment. I'm sure this battery is awesome, but it doesn't fit the two different applications that a normal 18650 does. I wish they had advertised this in the description. If your device doesn't have tight tolerances, this might be a great battery. Not a cheap roll of the dice though...
Answer: yes
