Next, you need to identify the positive and negative terminals on the battery. The positive terminal is usually marked with a plus sign (+), and the negative terminal is usually marked with a minus sign (-).

It’s important to identify the positive and negative terminals correctly before you start charging the battery. If you connect the charger to the wrong terminal, you could damage the battery or even cause an explosion.
