Possible issue with purple efest 18650 35a battery

Howdy,
Just got two of these batteries in the mail today. After charging them both, then checking with my meter they read a solid 4.2 volts. However, one will not fire on my black copper stingray clone but the other has no issues. Its not getting hot, and I don't notice anything peculiar about the appearance. Does anyone know what's going on? Thanks in advance.

Is the wrapper on the bottom preventing connection?

Is the wrapper on the bottom preventing connection?

That would be my guess too.

Wow, I feel like am idiot. Thanks guys. I pulled the wrapper back on the one (it was actually covering more then the one that was working) and presto!

Well, about a two months ago I got a pair of purple 350's, in less than a week one of them would no longer fire any of my devices, while the other one worked just fine. Like you, I discovered this after pulling the battery fresh off the charger, and it was working prior to recharging it .. I chalked it up to the fact that Efest is simply a janky brand of batteries, which I knew going in, but I needed some flat top 350's.

Never had any problems with any of my Efest Batteries.

Have read many many post about Stingrays not firing and am willing to bet a lot of those are Stingray Switch/Battery Wrap relationship issues.

I have an Efest 18650 35A flat top purple and a Sony VC4 18650. I don't use the Efest on higher settings or super low ohms, only the Sony. Or does anyone know if the Efest 35A would be safe to use in a DNA 30 mod?

No reason to think it would not work fine. DNA is a Regulated Mod with built in protection.

I spent over an hour with my stingray clone and a multimeter trying to figure it out. Finally found the button contact was too big for my battery. I have had sonys and efests both not work and work. It must be a close thing and it differs from battery to battery in the same line,

I love my efests. I have 1 purple, 1 red, and 1 black. And 4 efest 350's. These little guys are awesome.

I have one of the 35A Efest 2600's 18650 and would like to get another. The mod box I was using I believe was faulty, not the battery itself. They aren't a hot battery, had a chance to use it in my Cloupor DNA 30 mod and its performing beautifully.

Oops, 2500's not 2600's
