Samsung 25r FAKES! What's really beneath the wrapper?

[Vap0r Lew]

OK guys bash me if u want but, ere goes.
I have purchased a lot of (what I thought was) authentic samsung 25r batteries. After posting a pic someone pointed out they were fakes/clones. My big question is.... if they are fakes/clones, how can you be sure and MOST IMPORTANTLY WHAT ARE THE TRUE SPECS ON THESE? someone said they were just as bad as a trustfire 5A battery. If that were so then they would've already vented on me. I've been using them in my sigelei 150W with builds around .3-.15 Can anyone enlighten me on this subject?

Where did you purchase them from? Authentic Samsung 25r's are 20A CDR.

Samsung 1865025R are a high drain, safe chemistry, 2500 mAh, 20 amp continuous, light blue IMR/hybrid battery. The ones I have are flat tops. These are among the best batteries for vaping at the present time, along with the LG 18650HE2 2500 mAh 20 amp continuous. Unlike most of the batteries on todays market, Samsung actually makes these batteries themselves. If you purchase these from reputable vendors like RTD Vapor, Illumination Supply, Lighthound, or Orbtronics you can be assured that the batteries are authentic.

I wouldn't fire any coils under 0.4 ohm with these Samsung 25R, as I pay no attention to "pulse" amp ratings, only heeding "continuous" discharge ratings. This allows for some safe headroom should a post screw become loose and change the resistance of the coil. In addition, I believe we put a lot of faith into these cheap Chinese made ohm readers to make accurate measurements.

I'm not really a new vaper I've been vaping over 2yrs now and know about just about all of it and I do hvac work so I've been familiar with ohms law for over 10yrs. My real question is what are the specs on the clone batteries? Does anyone know if the specs are different? Literature would be greatly appreciated!

 

[Vap0r Lew]

O yeah.... my ohm reader is a 120 dollar fieldpiece multimeter lol I'm pretty sure it's accurate [edited] lol field piece is a big brand name meter in the hvac industry

As far as I know clones of Samsung 25R's don't exist.

I think the dude talking to you was blowin' smoke up your ..... Where did you buy the batteries?

I've not read of Samsungs being cloned, just AW and Sony batteries. Purple Efest batteries are re-wrapped Sony, LG, or Panasonic batteries. Purple Efest Batteries

There is no way of knowing the specs of a cloned or fake battery. An unscrupulous/ignorant vendor selling a "fake" battery is not going to admit that it is a fake, if he actually knows that it is a fake to begin with. It's basically an unknown battery by an unknown manufacturer with unknown specs. This is why the vets here preach to purchase batteries from reputable vendors like I gave you above, who can verify their sources.

Post a pic of the battery with n without a wrapper

What's written on the actual cans?



And that's not true about automatically venting.
I'm many tests on youtube forced shorting either melted the wire or just killed the battery outright, in many cases they have to seriously abuse them to get any effect at all.

Samsung wouldn't be the no 1 battery used in power tools if they vented that easily and I have destroyed my share of battery packs with no effect except dead cells

Clone batteries can be anything including used batteries salvaged from laptop battery packs.

Looks legit to me..

Imo, the batteries most likely to be bogus are the ones claiming umpossible stats, like 35A continuous amp limit (I saw some batteries claiming 40A continuous, just asking for some idiot to blow their face off).

 

[Vap0r Lew]

these are the pics from the person claiming mine were Clones they stated that the one on the left was authentic

 

[nyiddle]

Huh, so there is a difference..

That said, I'd guess the ones on the left for fakes. The contact seems way too small on the one on the left.

Baditude? Looks like you've got another mystery on your hands.

I compared the pics to my Samsungs. Mine have the larger white ring on the positive end like that one on the left. That's all I'll say about this other than what I've already said about buying batteries online. Batteries are the one thing NOT to skimp on.

Ditto for mine.

With the real sony's running dry the cloners are moving on to the next scam...only buy from reputable vendors...I go with illumination supply.

 

[snork]

Ditto for mine.

Mine as well.

 

[Thrasher]

........

 

[caramel]

Looking at pics from reputable vendors.... they all show a three vent holes top cap.

One on the left definitely clone right ones are legit.
