Is Red Positive On A Car Battery

Is red positive on a car battery? This is a question that we often get asked and it’s one that can be a bit confusing. After all most batteries are black and have positive and negative terminals that are clearly labeled. So why is it that some car batteries are red and have positive and negative terminals that are not labeled?

The answer has to do with the way that car batteries are made. Most car batteries are what are called lead-acid batteries. Lead-acid batteries have two terminals one positive and one negative. The positive terminal is usually larger than the negative terminal. The lead-acid battery gets its name from the fact that it contains lead plates and lead dioxide.

When the lead-acid battery is being charged the lead plates give off electrons which flow to the lead dioxide. This creates a charge on the lead dioxide which attracts the electrons back to the lead plates. The lead dioxide becomes positively charged and the lead plates become negatively charged.

The reason that the positive terminal is usually larger than the negative terminal is because the lead dioxide becomes polarized when it is charged. This means that the electrons tend to flow to the positive terminal more than the negative terminal.

So to answer the question yes the red terminal on a car battery is usually the positive terminal. It is important to remember however that it is always best to check your car’s owners manual to be sure. also be careful when working with batteries because if you reverse the terminals you can cause damage to your car’s electrical system.
