Car battery maintenance when car not used

Car battery maintenance is essential for every car owner. If you don’t take good care of your car battery, it can fail to start your car, leaving you stranded wherever you are. One reason why a car battery can fail is when your car is not used for an extended period. If you have to store your car for weeks or months, you need to take some necessary measures to ensure that your car battery remains in good condition. In this article, we will discuss some essential maintenance tips for a car battery when your car is not used.

The first tip for maintaining your car battery when your car is not used is to disconnect it from your car. The reason is that even when the car is not running, the battery supplies a small amount of power to the car’s electronic system. The continuous discharge of the battery if the car is not used eventually damages the battery. Therefore, disconnecting the battery is the best practice to prevent a complete discharge.

Another important tip is to keep your car battery clean and dry. A wet battery can cause a short circuit and damage the internal components of the battery. Additionally, keeping the battery clean ensures that the terminals and cables are free from dirt or corrosion. You can clean your car battery with a damp cloth and remove any corrosion using a wire brush.

In conclusion, taking care of your car battery when your car is not used is crucial to maintain its performance and prolong its lifespan. Disabling the battery, keeping it clean and dry and checking it periodically can help ensure that the battery is ready to use when you start your car again.

Keep Your Battery Charged

Keep Your Battery Charged

When your car is not in use, it is important to keep the battery charged to avoid a dead battery. You can use a battery maintainer or trickle charger to keep the battery charged, or you can start your car and let it run for 15-30 minutes every few days. Make sure to check the battery and charging system regularly to avoid any surprise problems.

Another way to help maintain your car battery when not in use is to store it properly. Park your car in a cool, dry place and avoid extreme temperatures and humidity, which can cause the battery to deteriorate. Remove the battery if you plan to store your car for an extended period, and keep it in a clean, dry area with a constant temperature of around 60-70°F.

Test Your Battery

Even if you take proper care of your car battery during periods of inactivity, it is still a good idea to test it periodically to make sure it is holding a charge. You can use a multimeter or have a mechanic perform a load test to check the battery’s condition.



By following these tips for car battery maintenance when not in use, you can help extend the life of your battery and avoid the frustration of a dead battery when you are ready to hit the road again. Take the time to properly care for your battery, and you will be rewarded with reliable performance for years to come.

Types of Car Batteries

Lead-Acid Batteries

Lead-Acid Batteries

A lead-acid battery is one of the most common types of car batteries. It stores electrical energy by using lead and lead dioxide plates and a sulfuric acid electrolyte. These batteries have a well-established technology and are known for their reliability and durability.

There are two types of lead-acid batteries: flooded (wet cell) and sealed (Valve Regulated Lead Acid, or VRLA). Flooded batteries require maintenance, such as adding distilled water to them. Sealed batteries are maintenance-free and do not require any watering.

Lithium-Ion Batteries

Lithium-Ion Batteries

In recent years, lithium-ion batteries have become more popular in the automotive industry. Lithium-ion batteries are lighter than lead-acid batteries and have a higher energy density, which means they can store more energy in a smaller space. They also have a longer lifespan compared to lead-acid batteries. However, they are more expensive.

Currently, lithium-ion batteries are mostly used in hybrid and electric cars. They are also used as a replacement for lead-acid batteries in some vehicles, but this is still not common.

Agm Batteries

Agm Batteries

AGM (Absorbent Glass Mat) batteries are a newer technology and are a type of valve-regulated lead-acid (VRLA) battery. These batteries use a fiberglass mat to absorb and immobilize the electrolyte, which allows them to be sealed and maintenance-free. AGM batteries are reliable, have a high power output, and can handle high temperatures.

They are commonly used in high-performance cars and motorcycles, as well as in marine vessels and RVs due to their resistence to vibration and cycles of charging and discharging.

  • Lead-acid batteries are the most common types of car batteries.
  • Lithium-ion batteries are becoming more popular in the automotive industry.
  • AGM batteries are a newer technology of lead-acid batteries.

When choosing a new car battery, it’s essential to consider the type of battery that suits your vehicle and driving needs. Factors such as the climate you live in, how often you drive, and the types of systems and accessories you use in your vehicle can all affect the performance and lifespan of your car battery.

Reasons for a Dead Car Battery

1. Lack of Use

When a vehicle is not used for a long period of time, the battery can gradually lose its charge. This can happen because the battery is slowly discharging on its own, or because electrical systems in the car are still drawing power even when the car is not running. If the battery loses too much charge, it may not be able to start the car when you’re ready to use it again.

2. Extreme Temperatures

Both hot and cold temperatures can affect the lifespan of a car battery. Extreme heat causes fluid in the battery to evaporate, leading to a breakdown of internal parts and a decrease in battery life overall. On the other hand, cold temperatures can make it harder for the battery to generate power, which can make it difficult to start the car. In both cases, extreme temperature fluctuations can reduce the lifespan of a car battery over time.

3. Overusing Electrical Systems

Electrical systems in a car, such as lights, radio, and heated seats, all draw power from the car battery. If these systems are used excessively or left on when the car is not running, it can drain the battery’s charge faster than it can recharge. Over time, this can cause the battery to die prematurely.

4. Corroded Connections

If there is corrosion on the battery terminals or other connections, it can interfere with the flow of electricity and cause the battery to lose its charge. Corrosion can often be prevented by keeping the battery clean and checking it regularly for signs of damage or wear.

5. Age

Lastly, car batteries simply wear out over time. Even with proper maintenance, a battery will eventually reach the end of its lifespan and need to be replaced. Knowing the age of your car battery and keeping track of its use and maintenance can help you anticipate when it may need to be replaced.

  • In summary, common reasons for a dead car battery include:
  • Lack of Use
  • Extreme Temperatures
  • Overusing Electrical Systems
  • Corroded Connections
  • Age
