When it comes to car batteries, understanding the basics of how they work is crucial for maintaining a healthy and reliable vehicle. One of the most common mistakes that car owners make is mixing up the positive and negative terminals of their car battery. This can lead to a range of problems, from a dead battery to a potentially hazardous situation. In this article, we will delve into the world of car batteries and explore what happens if you put the negative on the positive car battery.

Understanding Car Batteries
A car battery is a type of lead-acid battery that stores chemical energy in the form of lead plates and sulfuric acid. The battery has two terminals: a positive terminal (also known as the cathode) and a negative terminal (also known as the anode). The positive terminal is marked with a “+” sign, while the negative terminal is marked with a “-” sign.
The positive terminal is connected to the battery’s positive plate, which is made of lead dioxide. The negative terminal is connected to the battery’s negative plate, which is made of pure lead. When the battery is connected to the car’s electrical system, the chemical reaction between the lead plates and the sulfuric acid produces electricity.
How Car Batteries Work
Here’s a simplified explanation of how car batteries work:
- The chemical reaction between the lead plates and the sulfuric acid produces electrons.
- The electrons flow from the negative terminal to the positive terminal through the car’s electrical system.
- The electrons flow through the car’s electrical system, powering the car’s accessories such as the lights, radio, and engine.
- The electrons then flow back to the negative terminal, completing the circuit.
This process is known as the electrochemical reaction, and it’s what powers the car’s electrical system.
Why Mixing Up the Terminals is a Problem
Mixing up the positive and negative terminals of a car battery can cause a range of problems, including:
- A dead battery: When the terminals are mixed up, the chemical reaction between the lead plates and the sulfuric acid is disrupted, causing the battery to drain quickly.
- A blown fuse: When the terminals are mixed up, the electrical system can become overloaded, causing a fuse to blow.
- A short circuit: When the terminals are mixed up, the electrical system can become short-circuited, causing a spark or even a fire.
These problems can be costly to repair and can even cause damage to the car’s electrical system.

Immediate Effects
When you put the negative terminal on the positive car battery, the immediate effects can be:
- A loud bang or spark: When the terminals are mixed up, the electrical system can become overloaded, causing a spark or even a bang.
- A dead battery: When the terminals are mixed up, the chemical reaction between the lead plates and the sulfuric acid is disrupted, causing the battery to drain quickly.
- A blown fuse: When the terminals are mixed up, the electrical system can become overloaded, causing a fuse to blow.
These immediate effects can be startling and potentially hazardous.
Long-Term Effects
The long-term effects of putting the negative terminal on the positive car battery can be:
- Battery damage: When the terminals are mixed up, the chemical reaction between the lead plates and the sulfuric acid can cause damage to the battery.
- Electrical system damage: When the terminals are mixed up, the electrical system can become damaged, causing problems with the car’s accessories.
- Fire risk: When the terminals are mixed up, the electrical system can become short-circuited, causing a spark or even a fire.
These long-term effects can be costly to repair and can even cause damage to the car’s electrical system.
