Which 18650 batteries do you trust?

[Lobby]

One other thing to keep in mind is to keep an eye on your batteries wrapper. I used to have to rewrap my batteries every couple of months. One of the mods I used to have tore wrappers often.

There appears to be a new Molicel, the M35a. Has anyone tried these or is there any reason why they shouldn't work well in our vapes?

"Manufacturer Rated Max Discharge Current: 10A"

Tinymight definitely wants 20A discharge and I think firewood and others likely do as well.

Confirmed same for firewood per the site.
"Please note, battery must be a flat top 18650 capable of supplying 20 Amps discharge current (minimum)."

 

[cybrguy]

Thanks, I didn't notice the amperage.

 

[anome]

Depends, but IMO
- Manufacturer Rated Max Discharge Current: 10A
seems to come up short for most use cases.

 

[FlyingLow]

I have not bought batteries in ages... any new developments? My old molicells do not hold charge like they used to.

Specifically shopping for 18650's for TOAD, TinyMight2 and P80.
Do I rebuy molicells?

 

[passenger]

I just bought a couple P28a to replace my older ones and they are still in high regard it seems. Never had an issue with those.

I'm very much a Molicel kind of guy these days. I have one set of the P30 s that seem to perform a little better in my Wand than the P28 but I'm still very happy with the P28s. I think I'll be buying the P30 for my next order, tho, especially if they are no more expensive.

Excuse my lack of battery knowledge, but do the sale Molicels work in TM2, Wand, DaVinci, Xmax even if they say they are not for vapes? Do they mean not for box mod vapes?

law yer speak to get around stupid laws.

Yes, the manufacturers are just covering their collective asses. Remember, cells like 18650s were never intended to be sold to the general public. They were always meant for OEMs to build their proprietary battery packs. In that scenario, users would never have a chance to f*ck up and cause a big oopsie.
I am sure the manufacturers have been sued a few times by idiots who f*cked up and tried to put the blame on the manufacturer. With that little warning on the battery, that should come to an end.

But yeah, if you have verified that your battery can deliver the amperage required by the device, you're good to go. Can't go wrong with (authentic) Molicel.

Stupid question that I'm probably being overly cautious over, and apologies if this isn't the right place to post, but one of my 18650 Molicels has attained a very slight nick in the plastic casing. I am sure there is no actual cell damage or perforation, I just always hear warnings repeated about not using batteries if the "casing is damaged" and I'm wondering is something like that a true safety issue?

I'm always very careful handling these batteries, I treat them like sticks of dynamite. Always kept in case when not being used and never charged unattended. The only way this could have happened would be my XTAR VC2 charger's retractable contacts snapping back and scratching it upon removal.

Any answers would be appreciated, battery safety is of the utmost importance.

I would rewrap it
Theres a tutorial video here

As cool and aesthetic as ours are, battery wraps aren’t used solely for keeping up appearances. They’re really there for safety reasons. High-quality bat

I recommend using PVC ones and avoiding the printed ones as the printed ones are usually a lot thinner

Ah a lot of fucking around then. If it helps, the nick in the casing is tiny, way smaller than the example shown on the video. I only use them in a Tinymight 2 and always in the plastic case when not in use or being charged. If it comes to it I'll order a new battery lol

 

[Hippie]

The real danger is the positive end becoming exposed, and shorting
So I'd buy the wraps now so you have them ready and monitor the situation

It worried me 1st time but now I've done it about 10 times, that's not an issue - with a little prep so the battery doesn't roll away or anything silly like that. It's just shrink wrap, you slip the clean battery and the insulator in the wrap, centre it all, and shrink it with some heat.
( and then do it again as most likely you'll not quite get it centred correctly 1st time lol )

Oh it's nowhere near either terminal end it's just a tiny patch on the side near the technical specs, everything else is entirely intact. Ty for the help though I appreciate it.

Re wrapping is pretty easy to do once you've done it a couple of times. These batteries have a lot of power and a short can be somewhat explosive or start a fire. At $3 to $10 each, if you don't want to be bothered rewrapping I personally would just replace them rather than risk a short. But I'm a boomer, so I know nothing.

If I'm not too vaked this evening I'll try and upload a photo of what I mean and you can see how inconsequential of a nick I'm talking about, the casing is 99.9% intact. I appreciate the caution though and I will be extra careful with it, of course.

 

[cybrguy]

In truth, a TinyMight in particular is probably not as much of a risk as a lot of other vapes in terms of stressing a tear in the wrapping. The walls inside the battery chamber are wood (at least in my T1s) so I think it might be hard to actually short. I still, as a matter of principle, always rewrap batteries that have a tear in the wrapping or insulator because it is easy.

Samsung or Panasonic.....have always found these to be reliable and long lasting

Hey, I got those sale Molicels and they are great. My TM2 is working again! Thanks @budski et al.

 

[simba]

Doesn't matter how tiny the nick in the battery wrap is, I would still rewrap them. It's very easy to do and wraps are cheap to buy. I would not take the risk to keep using those batteries in that condition

There are places that can re-wrap batteries, right? Just in case I'm not brave enough...

I've got a couple hundred I use some for my drone equipment, receiver and goggles. My dad collected them years ago. I have way too many, lol
