Great Cases

These are strong and easy to use cases. These are great for organizing and keeping your batteries safe, especially in your emergency bag.

These cases are always great

I've been purchasing here for about a decade now. These cases have lasted throughout. One was EDC for 7 years without issue. Tip: Strategically add thin insulation foam tape for avoiding noise when carrying in a bag or pouch.

Tough and doesn't open in your bag or pocket. I bought these to carry spare batteries for work. They do the job of protecting my 18650s very well. Highly recommend these

Recommend for those who carry extra batteries
May 12, 2019
For those who carry torches in the daily (edc). I recommend carrying extra batteries just in case you forget to charge it. Keeps it safe from coming in contact with keys and change. Great for storing them in: bug out bags, first aid, edc, tool box, lunch bag, etc.
The Ultrafire Battery Case is a safety step you shouldn't ignore
March 24, 2019
Carrying loose batteries of any type is a risk but particularly Li/Mn Type products (like the 18650 batteries used in vaping devices) the Ultafire Battery Case is an inexpensive precaution you should take.

But I give it a 4 instead of a 5 because while some of the cases I purchased will fit 2 18650's quite well, some of them are almost too tight to close properly. But they do close.
ProsGreat price
ConsSome are a little tight fitting.

Works better for CR123A/RCR123A's
December 31, 2016
Due to the nature of things Lithium Ion, 18650's tend to vary a bit in length and girth, so sometimes a bit of extra force is required to close this case if one or two 18650's are being stored... this makes for a concern the case will pop open, letting these powerhouse cells free to get into trouble. Double check your case to insure it locks up well. This style closure isn't the type Tenergy employs in its AA and AAA cases, which gives a better sense of secure closure, even making it a bit harder to open. This case closes more securely with the bit thinner CR123A's and RCR123A/16340's. With these the fit is a bit loose, so there's some rattling, but by the same loose fit the cover snaps shut more securely without the resistance of a plump 18650 cell fighting it. I also find that pairing one 18650 with two CR123A's works nicely, but if you pair with two RCR123A/16340's, you may find that due to the variance in length of the RCR123A/16340's maker by maker, two of these placed alongside the 18650 may also interfere with the fit and closing.
ProsHolds 4 CR123A's or 4 RCR123A/16340's nicely, closes reasonably securely with these Can hold 2 18650's or a single 18650 plus two CR123A's alongside Comes in two colors to separate types of cells being stored more easily
ConsMay not close securely with certain 18650's due to diameter - be careful to check and press firmly to close lest these cells roam free in your luggage

A Inexspensive plastic case
December 16, 2015
This is just a inexpensive plastic case, the case has slots for the batteries 123's to lay vertical or horizontal the 18650's lie vertical. "Rattle and Roll" the batteries fit very loose in the containers/ holders and rattle every time you make a step.
ProsUhh their blue...
ConsThe batteries fit very loose in the container and rattle every time you take a step

CR123 case

Item does what they say. It holds batteries. I don't own any 18650s so I have only used it for CR123. I have no doubt that they would fit.

Handy battery case
March 27, 2015
I agree with the other reviewers. These cases do their job of keeping your 18650s and CR123s secure and together. However, thicker 18650s will make the case hard to close and even harder to open due to the tight fit. You may need to use more than just a fingernail to open the little tab. If the batteries are on the thin side, and there is no pressure on the lid, the locking tab my not hold very well either. A rubber-band will solve that problem though. All in all, a good product to have for those size batteries. (*Note: This is the same case that comes with the Olight 18650 battery if you chose the box and not the blister pack.)

18650 battery fits snugly into place, and lid snaps shut. Would get another one, also customer service and the time it took to get here was very good.

case 18650 / CR123
February 18, 2015
Not a bad little case, but slighly a pain to open. And i found it can just kinda pop open at times. Solid enough to protect your cells, but if your throwing these in your pack or gear bags ect, I would just throw a quick rubberband around this case just to be one the safe side. With lithium cells , trust me they arnt anything you want loose in a gear bag with any metal objects.Yeah i found out the Scary hard way.
Prossolid enough to protect cells. clear see thru (easy identifiable cells)
Conssometimes hard to open. Sometimes just pops open on its own with the slightest bump. Not really reliable enough to be handled roughly or abused.

Not a tight fit.
February 5, 2015
The case fits CR123 but they rattle around and do not fit tightly. My Klarus 18650 do not fit because they are slightly oversized so overall I ended up not using these cases.
ProsTight snap closure Small size
ConsLoose fit
