Is your battery terminal hot to the touch? It’s not just you; it seems like everyone is noticing their batteries are overheating. Ever wondered why this is happening? Then this article is here to help!<\/p>\n
Battery terminals are hot for a few reasons. To understand why it’s important first to know what a battery terminal is and how it works. A battery terminal is the connection point between an electric circuit and the battery. It’s usually made from metal which means that when you’re charging your phone or laptop<\/a>, the heat generated by these devices will be transferred to its metal case through conduction.<\/p>\n If you have ever touched a battery terminal, you know that they are hot. This is because when batteries discharge, energy from the chemical reaction inside is converted to heat and carried away by electrons in the battery.<\/p>\n When a car<\/a> is in use, electricity flows from the positive terminal to the negative. The reason that it gets so hot is because of this flow of energy. As opposed to when you have your battery plugged into an outlet, and both sides get warm or even very hot, with batteries, there’s no current going back into the battery. Instead, that energy is being converted to motion and light with your car’s engine; this conversion requires a lot of power, making the terminals hot.<\/p>\n Be sure not to touch the hot battery terminal, as you could get burned, and there’s a chance that battery acid might be present. It should feel warm but shouldn’t burn your hand if you simply stick it into the water.<\/p>\n Another reason that the terminals get hot is because of electrical resistance and how power works in a circuit. As we discussed earlier, electricity flows from positive to negative. However, there’s always some amount of energy lost as it travels through your car’s components like wires and such; this loss creates heat which can make those parts warm or even hot.<\/p>\nWhat causes negative battery terminals to get hot?<\/h2>\n
