Cell phone battery antenna problem

Cell phone battery why there are three tentacles? What is the effect of that antenna?

Answer:

There are three terminals in the general lithium: + / - / T or + / - / C, compared to high-end, such as the camera's lithium battery there are four terminals: + / - / T / D or + / - / C / D.

Because the T / C / D three terminals only with the corresponding product when used to play a specific part of the function, and charging is not necessarily linked, so the general charge only connected to the +/- terminal.

Battery positive, battery type identification test contacts, battery negative, battery type recognition is very important, Nokia many mobile phone if you do not connect the contact will refuse to boot, Motorola will display invalid battery. SIM card reading failure and battery does not matter.
