Is this a safe battery?

[card]

Two of these came with a clone mod I ordered off ebay. I've been using them for about a month now with a shortstop fuse. With the shortstop fuse any time I go below about 1.8 ohms the fuse kicks in and vapor stops. There is no short, it always does this when I use a lower res coil. Right now I'm using a 1.5 ohm coil and the fuse kicks in after about a 2 second drag. So I'm considering ditching the shortstop but I want to make sure these batteries are safe first.

Maybe its these old eyes, but I can't tell what that is. What is that?

oops let me attach a better photo

Does it have an "AW" on it anywhere? What does the label say on the battery? 2000 mAh anywhere? "IMR" anywhere?

There's probably a good reason why the Shortstop fuse is kicking in. What juice delivery attachment are you using?

If there is no identifiable labeling on the battery, I personally wouldn't use it without the fuse.

It looks like a good one (colorwise), but as Baditude stated: there should be a "AW"-sticker on it and "IMR" written on it to be a save battery.

in the meantime the writing on the battery says:
IMG 18650 2200MAH 3.7V

Sorry to say, never heard of it. Meaning it's crap. Get yourself some good battery before it blows.

Depends What APV are you using it in.?

If you are using in a Mechanical than most experienced vapors wouldn't suggest it.
Only use high drain batteries from reputable sources in mechanicals

If in a VV, most have built in protection circuits and you should be fine. But it's your risk to take.

 

[Choc_Addic]

Yep. I wouldn't use that on a mod. May be ok to use in low power led flashlight!

 

[Baditude]

It's a generic battery disguised to look like the red AW IMR batteries. As always, consider the source (Ebay).

Genuine AW's IMR batteries are either 1600 mAh or 2000 mAh and will have an "AW" sticker on them.

I wouldn't even use it in a flashlight.

 

[Choc_Addic]

I might, but very very carefully.!!

The shortstop is also tripping when I use a 1.5 ohm coil and an Efest 18350 800 mah version 2 IMR that I bought from Fluid Vapor.com. Now I've read that these are actually good batteries. Would this suggest that the fuse is too sensitive? Im using these in a sigelei 20 mech and the no names are using in a caravela clone mech. My delivery system right now with my 1.5 ohm coil is an Igo L.

Since you are using a rebuildable atty, you may very well be pushing those batteries' amp limits and tripping the fuse. You might be sorry of the results if you use the batteries without the fuse on the RBA. I'm not familiar enough with the Efests to know their amp limitations.

I'm not a fan of Efest batteries. I have tried a pair in both 14500 (for a mechanical mod) and 18350 (regulated mod) sizes, and neither pair could compare with my usual AW. My only other recommendations would be Panasonic or MNKE for RBA usage.

Please note that a higher mAh rating is not an indication of the quality of the battery. There are no guidelines set for manufacturers in how they list their mAh ratings, and many inflate the rating to impress and entice customers that are not in the know.

Ok, So I put in the other 18650 no name and it fired great for a full 10 second pulse. The next pulse it cut off after about 3 seconds could this be an indication of pushing the battery's amp limits?

How do you determine the continuous discharge rating, where can I learn more about this?

Some good info in this thread from earlier in the week about 18650 batteries:

Never heard of an IMG and that doesn't sound promising.

The battery labeling can be deciphered as follows:

- Branding (AW or MNKE or Panasonic)
- Battery chemistry (IM = Manganese based, IC = Cobalt based, LFP = LiFePO)
- charging type (R = rechargable)
- Dimensions (first 2 digits is diameter, next 2 digits are length, 0 at the end for cylindrical)

So, an AW IMR 18650 is:
- Branding = AW
- Battery Chemistry = IM (Manganese based)
- charging type = R (rechargable)
- Dimensions (18mm in diameter, 65mm in length, 0 for cylindrical)

So, a battery labeled IMG doesn't make sense to me and would indicate a very cheap knockoff. As a comparison, the really cheap grey DKL batteries I have are on the low end of the scale but they're still properly labeled as ICR 18350.

The discharge rate is either listed in the product documentation or you can find people who have done bench tests on the internet, usually on flashlight forums. A quick search on Google pulled up this product page for the Efest 18350 max discharge rate Efest IMR 800mAh 3.7v 18350 Battery

Also, the 8c is based on the mAh. So, 8c means 8 times the mAh, in this case 800, to give you 6.4A as the max continuous discharge. In addition, your shortstop has its own Amp cutoff, usually 5A.
