I have a problem with Sony 18650 vtc5. It won't work, any advice?

Hi, I'm new here (and to forums in general) so not sure if this question should be here or not. Anyway I have a problem with an 18650 Sony vtc5 battery. I ran the battery in my copper nemesis with a .5ohm build for a few days. Then a buddy of mine upgraded to a brass stingray with a magnet switch. I gave it to him to use. It fired a few times. And now nothing?!? It no longer works in any mod with any size build. It does nothing when I put it on my i4 Intellicharger. I've already bought new batteries but is there any saving this one at all??

Did his mech get hot at all when this happened? You really need a volt meter to tell what is going on now with that battery. If something happened that caused the voltage on that battery to drop waaay low your Nitcore doesn't have the smarts to recover from that.

I agree with Rick. Either your buddy over-discharged your battery during use and its dead, or he somehow shorted the battery and it unknowingly vented dead. What was his coil resistance? Did anything get hot while he used your battery?

The only way to see what's going on with the battery is to use a digital multimeter or 510 voltage meter to measure the battery voltage level. If it still has 2.5 volts left, it could be revived with a top quality charger like an xtar VP1.
