UltraFire 2*18650/2*17650/4*CR123A Battery Protective Case (2-Pack)

Pros: Cheap, and useful carring space.
CR123s can be store in width.
4 batteries in it.
18650 protected can be store
but a bit narrow and close.

Cons: There's no logo of Ultrafire.
A bit hard to open with nails.
Because the open bump is too small and hard.

Other: I think these are cheapest cases you can find.
Looks solid and tough.
Useful cases I think.
There's no logo of Ultrafire.
A bit hard to open with nails.
Because the open bump is too small and hard.
but I don't care.
feels good.

Pros: It is a case to put those all important batteries in. The case is made of a semi-soft hard plastic, flexible enough to not break, and hard enough to resist crushing. Batteries fit very well inside the case and minimize movement. Not too loose and not too tight; like it was made to hold those batteries. The latching portion of the case also holds the case closed very well.

Cons: None that I can think of at the moment, only time will tell on how well the case resist oxidation.

Other: If you are looking for a nice case for your batteries, to keep them clean and protected from shorting when they are not being used, then these handy little cases just might be what you are looking for.

Pros: - Keeps all loose batteries (which fits in) in safe and order.
- No need to fear short circuit.
- Easy to take spare batteries with you, inside pocket, bag...
- Covers batteries from scraps
- The structure is quite solid, 1.5 mm thick plastic with reinforcing fins inside...

Cons: ... but the fins are only on lower part. That makes the upper part more flexible and the batteries inside will rattle too. The fins should be on both parts.
- The case is not splashproof nor watertight. That is bad for outdoor storage (camping etc.)
- A little mold tension was noticeable in both cases and the seams were not firmly together (after closing)

Other: A must have product to store batteries.
But for a watertight case, you need to draw a plastic bag over the case (like Minigrip).

Pros: It is a good battery case to protect your batteryes from scratches and bumps, short-circuits and other disasters, not from water.
it fits well 4 cr123, they rattle a bit but it isn't so bad.
excellent if you are scared about losing your precious rechargeable cr123.
excellent if you are scared about short-circuiting your batteries.

Cons: the hinges are a little weak, i think they will broke in the long time, i don't care, they are very cheap...

Other: buy as many as you need, you won't be disappointed.

Pros: -cheap, cheap, cheap -solid material -protect your cells from short circuits, bumps and bruises, scratches and other issues when transporting (but not waterproof) -each case fits 4XCR123 or 2X18650 -fits protected cells

Cons: -snap closure is weak -hinges feel flimsy

Other: Protect your precious cells with these inexpensive cases (dangerous if handled improperly). Excellent value, can't go wrong at this price
