Advice My eGo III Twist died because of 5 press?

[peco77]

But why the battery won't turn on? It's not completely discharged so it should turn on. I press the fire button 5 times while charging and the battery goes wrong? What kind of fabrications are these eGos?

It could just be one of them things a brand new light bulb can work for 10 seconds or 10 years it could just be a bad one through i bet someone will be along soon with more ideas I do know if normal lithium batteries drop below a certain voltage they just die and wont charge again i'm not saying this is in your case through most mods have built in protection to stop them going to low

That's one I'd get an exchange for, it's conceivable that pressing the button while on charge will be a hard short but I'd just be guessing. 
If there's a serial number I'd check it against the manufacturer website, been there got the fake tee

Has the battery center pin stuck down? Try a wooden tooth pick, run it around the pin trying to force it upwards gently. If the pin is down too far the device wont work in anything.

To prevent this issue, always be gentle when screwing a cartomizer or charger on to your battery. Also if it triggers the short circuit protection, you first need to fix the short, then connect to charger to clear it
