When do you need to connect a battery to a negative terminal?

When using a battery for both charging and discharging, it is necessary to connect the positive terminal of source to the positive terminal of battery and negative source to the negative terminal of battery. OK got it, but what happens if you put batteries the wrong way?

What happens if the battery cable is wrong?

The battery cable will be designed automatically according to the position of the battery terminals. So the incidence of the wrongly connected battery rarely occurs because the cable will not be connected if the battery is backwards.
