How to put the positive and negative poles of the rechargeable battery, and the consequences of removing the negative wire of the battery

When we leave the car without starting for a long time, it is likely to cause a serious battery loss. At this time, we need to charge the battery by ourselves. However, some friends don't know how to put the positive and negative poles of the rechargeable battery, thinking that just leave them casually. But in fact, this approach is very wrong, and the consequences are unimaginable. In order to avoid abnormal phenomena, let's tell you how to connect.

In fact, the method of placing the positive and negative poles of the rechargeable battery is relatively simple. First, connect the positive pole of the rechargeable battery to the positive pole of the battery and the negative pole to the negative pole of the battery, and then press the charging button to start charging. But do not overcharge the battery frequently. Although the current generated by charging is not very large, because the electrolyte is in a boiling state for a long time, not only the fine particles on the surface of the active material are prone to fall off, but also the grid may be oxidized in severe cases. , Resulting in loose peeling of the active material from the grid.

The consequences of removing the battery's negative wire

You must know that the negative terminal of the car is connected to the body, and the body is originally metal, so the whole car is connected to the negative terminal. In other words, at the moment the negative electrode of the battery is removed, the car's circuit can no longer form a loop (the battery cannot continue to supply power). Therefore, when we disassemble the battery, we must follow the order of "negative first, then positive", otherwise it is likely to cause a short circuit in the battery.
