Sorry if I'm being naive but I just got a lithium -Ion rechargeable battery pack (8.4V 2000mAh(2C)) and guess what..Yeah it has got 3 wires (a red one,a yellowish creamy one and a black one).Now could u please tell me what each one means and also the need for doing this.Btw what does 2C mean ?
In the off-change your pack might actually be a Lithium polymer pack I advise you to read the whole page, since often those packs are unshielded and mishandling those can easily lead to fire/explosive hazards.
I think the above replies are not relevant to the query raised " battery has three wires?
Yes… some battery has three wired (black, red and probably yello)… these kind of batteries may be old models…
Red Positive
Black is Negative
Yello earth connection.
Nowadays Battery has two wires only.
(If you tried to connect two pin wire to the 3 pin wired mobile/tab . You can use normally BUT charge can’t be acceptable) Replace the same type of battery is advisable.
