How to Fix a 510 Ego battery:
Some Ego batteries can suddenly stop working. Most of the times the problem is the connector pin being pushed down too much by over tightening the tank to the battery. With 510 ego batteries it is always wise to screw the tank just enough to allow contact between the coil base and the battery head and avoid over tightening.
Some ego batteries have a spring loaded pin which is a very good feature to avoid this problem, other (specially the smaller ones) don’t have a spring loaded pin and sometimes if you over tighten it, the round small pin inside the 510 connector will sink deep down not allowing contact with the 510 thread of your tank (or your charger). That being the case, you will think you have a dead battery when in reality all you need to do (if possible) is fix the internal pin.
If you want to know if your battery has a spring loaded pin simply take a pen and try to push down gently the connector pin. If it moves down and comes back up it has a spring under the pin, if it does not move down, do not force it, it simply does not have a spring under the pin.
No power and no charge? Maybe it is just the pin, and if that is the case there is a chance you could bring your battery back to life.
What you must do is very simple but must be done very gently. Take a toothpick or preferably a pair of thin tweezers, or something of similar shape and gently pull up the center pin of the battery a little bit (and I really mean just a little bit). Introduce the toothpick between the pin and the thread wall. Do this on one side of the pin gently and go around the pin repeating the little pull on the other side until you lift that internal contact just a tad. Connect your battery and see if it works. If it still has no power then try lifting it up a little more, but be careful not to pull too much or the pin could detach completely from the battery (in which case you would ruin the battery).
Most of the times this simple operation brings the ego battery back to life so before disposing your battery you might want to give it a try, just make sure you do it gently.
Afterwards, just be careful not to over tighten the tank into the battery. Sometimes the thread of the tank is too long and if you tighten it all the way in it will push the pin back inside to the point of it loosing the contact. So try to screw the tank just enough to make contact and power up instead of screwing the thread all the way until it stops.
