Is this battery indent normal?

My son asked me if this indentation on the bottom of the Kamry 18650, is normal. I have no idea. The smaller battery doesn't have the indent. He just got the Kamry 101 yesterday. The battery came with it.

Thanks in advance, for any help.

p.s. He started to peel away the wrapper, then decided against it.

that is most definitely not normal and you should never peel away the wrapper. the exposed metal underneath can complete the circuit if it contacts the side of the kamry and fire even when not pressing the fire button. i would dispose of it and get a new one. i would recommend a sony vtc5

Being a telescopic mechanical mod (capable of using different size batteries), the K-100 is rather notorious for causing the above indenting by putting too much pressure on the battery ends when tightening the battery tube. It is not so much the battery, but the mod being used. You get what you pay for.

Edit to add the following: I would no longer use that battery. It's structural integrity has been compromised and it is more likely to vent in a catastrophic manner.

Almost looks like he tightened the telescoping tube down too much, not sure what the bottom post of the kamry looks like. I would recommend you check that, 'cause it will just happen again, no matter what battery he uses.

Any idea what we're looking for specifically - in the Kamry? What would tell him something is faulty?

With the design of the k100 switch I don't really see how it could be from over tightening. The battery rest on a spring with a insulator on top and a post comes through the middle of the spring when you push the fire button. Its more likely to be from pushing the fire button to hard or dropping it and it landing on a unlocked switch.

Interesting. We'll find out soon enough. If he can't afford a new, better quality battery tomorrow, I'll help him get it.

He's asking if it matters which way the IC chip goes on the battery in the K101. He said the indent resembles the button on the chip. He was told to use it when charging the battery - which he did with the large battery. It doesn't work in the Kamry when he puts the magnet towards the poll (on the small battery). But it works terrific when he turns it towards the firing button.

Thanks for your insight!

I used a K100 for about 8 months as my main vape device. I dented a battery like that once (but not quite that badly) when I dropped my K100 onto the button.

I assume when you mention the IC chip that it is a fuse, like the '2 cent' fuses we use in mechanical mods. If that is what it is, it's not critical to use when charging, but much more so when using the device.

IMO there is no way you can tighten this mod enough to make the battery dent without it firing constantly (without you holding the button down), even with a fuse in there.

I use Sony VTC3 and VTC4 batteries with my mechanical mods because they are very safe. My next battery purchase will be Sony VTC5s, unless something better comes along first. From what I've read of the Kamry brand batteries, they may not be the safest ones out there, but I'm not sure of that.

I do believe the '2 cent' fuses have a positive and negative end and need to put into the device the right way around.

I get the feeling reading some of the articles in the 'One Stop Reference Shop For New and Experienced Vapers' may be good for you both. I suggest at least Baditude's battery info articles and the one on Ohm's law to start with.

Bets of luck with it all :thumb:

If what you son was using is a safety fuse, then it is designed to fit via magnet to the negative (-) end of the battery (see above).


However, if what your son was using is a Kick module, then it is designed to lay on the positive (+) end of the battery (see below).
