Boom! Does the battery taste different?

The battery's dead.

One bite and you 'll have electricity.

I don't know if you were told when you were young that batteries like the remote control have power when they run out, and they can be used for a while

Bite battery life method

We use batteries 5 and 7 called carbon zinc-manganese batteries. The principle of their power generation is the internal chemical reaction. When the battery is out of power, the internal chemical reaction has been relatively full. Since the material of the skin of this battery is relatively soft metal zinc, the bite that adults used to say was to let the zinc show some more and continue to participate in the internal chemical reaction so that the battery has a part of the extra electricity..

But ...

What time is it to bite the battery?

Moreover, biting the battery can not distinguish between true and false. And ... And ...

Cell phones are all lithium batteries now.

This?

This video, I just watched it for a few seconds, and I was already watching it.

This guy has the acting skills of not losing small fresh meat, dare to fight and fight.

And the blast effects are real.

It is said that the guy took his female friend to buy an iPhone battery and then tested the battery for authenticity. He put the battery in his mouth and bit it. It could have been an IQ drop. It could have been an obsession. He used the battery as gold.

then

At first glance, he is not very strong, or the battery can not say fried.

I feel sorry for the girl next to me, but from the video, two people should be fine.

Since 16 years, the battery explosion has been frequently reported. Then came the battery door incident at Samsung note 7.

Then there's the iPhone battery drum, and the repair explosion and so on.

So what was the cause of the battery explosion?

1 . When the positive and negative poles of the battery are put together, when the battery is short-circuited, the internal heat and current will be very large. For lithium batteries that are sealed and packaged, the shell will burst and burn. The situation appears.

2. In another case, it is more common when a reary penetrates the skin of the battery, the chemical composition inside, lithium ions, and air oxidation, producing a large amount of heat, resulting in explosions.

3. Overcharge. When the power is full, the charging circuit will be automatically cut off because of the charging protection chip, but it is still not recommended to connect the phone to the charger in the energized state for a long time.

So, it's okay don't always touch your battery, if you want to change batteries, recommend to the mobile phone repair.
