Car batteries are an essential part of any vehicle, providing the necessary power to start the engine and keep it running. But what happens when you let your car battery sit for an extended period of time, such as during the winter months when you’re not driving it as frequently?
Many car owners assume that if they’re not driving their vehicle, the battery isn’t being used and will therefore last longer. However, this isn’t always the case. Letting a car battery sit for too long can actually have negative consequences, leading to reduced performance and even a shorter lifespan.
So, what exactly happens when you let a car battery sit? In this article, we’ll explore the potential risks and consequences of neglecting your car battery and provide some tips on how to keep your battery in good condition, even during periods of inactivity.
Effects of leaving car battery unused
1. Battery sulfation
When a car battery is left unused for an extended period, it is at risk of being affected by sulfation. This happens when the lead-acid inside the battery reacts with sulfuric acid and creates sulfates. The sulfates then stick to the lead plates inside the battery, making them harder for the battery to discharge when it’s time to start the vehicle. Sulfation can permanently damage a car battery or significantly reduce its life span if left unchecked.
2. Reduced performance
If a car battery is left unused for too long, its performance may be reduced when it is eventually used again. In extreme cases, it may take significantly longer to start the car or not start at all. In addition to sulfation, unused batteries may be susceptible to corrosion, which can affect the mechanical components required to start the car.
3. Electrical system damage
In rare instances, allowing a car battery to sit unused for too long may lead to damage to the vehicle’s electrical systems. For example, the battery may overheat and leak, causing corrosive acid to enter the engine bay and damage nearby wires. This is why it is essential to keep an unused battery at its manufacturer-recommended voltage levels or to hook it up to a charger to maintain this level.
To avoid the negative effects of leaving a car battery unused, it is best to follow the manufacturer’s guidelines for storage and maintenance. This may include storing the battery in a cool, dry place or regularly using a trickle charger to maintain its optimal voltage levels. By taking proper care of your car battery, you can ensure that it will be ready to go when you are.
What is internal corrosion?
Internal corrosion, also known as battery sulfation, is a common problem that occurs when a car battery is left sitting for an extended period of time. This is because the lead-acid battery is made up of a series of cells that contain lead plates and an electrolyte solution made of sulfuric acid. Over time, the electrolyte solution can evaporate, causing the lead plates to become exposed to the air and oxidize. Sulfation occurs when the lead oxide reacts with the sulfuric acid and forms a crystalline substance that covers the lead plates. This crystalline substance prevents the battery from being able to charge properly, leading to a loss of power.
How to prevent internal corrosion?
The best way to prevent internal corrosion is to keep your battery charged and use it regularly. If you plan on leaving your car for an extended period of time, it’s recommended that you disconnect the battery or use a battery maintainer to keep it charged. Additionally, it’s important to check your battery’s water level and add distilled water when necessary, as low water levels can lead to sulfation. Finally, keeping your battery clean and free of debris can also help prevent corrosion from occurring.
- Keep your battery charged and use it regularly
- Disconnect the battery when not in use
- Use a battery maintainer
- Check your battery’s water level
- Keep your battery clean and free of debris

Loss of capacity
What is loss of capacity in a car battery?
As a car battery sits unused, it can lose its ability to hold a charge, which is known as loss of capacity. This can occur due to a number of factors, including natural self-discharge, corrosion, and sulfation.
How does loss of capacity affect a car battery?
When a car battery experiences a loss of capacity, it may no longer be able to provide the power required to start the engine, which can lead to issues such as dimming headlights and a slow starting engine. Additionally, a battery with reduced capacity may be more susceptible to damage due to overcharging or undercharging, which can further reduce its lifespan.
To prevent loss of capacity in a car battery, it is recommended to:
- Ensure the battery is properly charged and maintained
- Keep the battery clean and free of corrosion
- Avoid leaving the battery unused for extended periods of time
- Use a battery maintainer or charger if the vehicle will not be used for several weeks or months
By following these best practices, car owners can help to ensure their battery remains in optimal condition and minimize the risk of loss of capacity.
What happens to a car battery when it sits too long?
When a car battery sits unused for an extended period, it can cause damage to the internal components, which leads to a shortened lifespan. The sulfation process occurs when the lead plates inside the battery react with the sulfuric acid electrolyte, forming lead sulfate crystals.
If the battery is left uncharged, the lead sulfate can build up on the plates, reducing the surface area available for chemical reactions and decreasing the battery’s capacity to produce electrical energy. Over time, this can cause the battery’s voltage to drop, making it less effective at starting a car or powering accessories.
How to prevent a shortened lifespan?
To prevent a shortened lifespan of your car battery, it’s recommended to keep it fully charged, especially if you aren’t using your car for an extended period. You can use a battery maintainer to keep the battery charged and prevent sulfation. Additionally, you can detach the battery from your car and store it in a cool, dry place to avoid extreme temperatures, which can also be damaging to the battery.
If your car is equipped with a modern electronic system, it’s recommended to consult the owner’s manual or a professional mechanic before removing the battery from the car to avoid resetting the electronic components.
- Keep the battery fully charged with a battery maintainer.
- Store the battery in a cool, dry place.
- Consult the owner’s manual or a professional mechanic before removing the battery from the car.
Difficulty in starting the car
When you let a car battery sit for a long period of time without starting your vehicle, you may experience difficulty in starting your car. This can be due to a few reasons:
- The battery may have lost its charge due to lack of use.
- The battery terminals may have corroded, creating a poor connection between the battery and the starter.
- The alternator may not be functioning correctly, preventing the battery from charging properly.
If you experience difficulty in starting your car, it is important to take care of the issue as soon as possible. Continuously trying to start the car can further drain the battery and cause even more problems. You may need to jump-start the car, replace the battery, or have the charging system checked by a professional mechanic.
What happens to a car battery if you don’t use your car for a long time?
If you let your car battery sit for a long time without using it, the battery will slowly discharge and lose its charge over time. This can cause the battery to become damaged, and it may not work when you try to start your car.
How long can a car battery sit unused?
A car battery can sit unused for several weeks or even a few months before it starts to lose its charge. However, the length of time depends on the battery’s age, condition, and capacity. If the battery is new and in good condition, it may be able to sit for a longer period without losing its charge.
Can a car battery die if you never use the car?
Yes, a car battery can die if you never use the car. If a car is left unused for an extended period, the battery will slowly discharge and lose its charge. This can cause the battery to become damaged and it may not work when you try to start the car.
