How Long Can A Car Sit Before Battery Dies?

Last year, the covid-19 global pandemic forced a majority of homeowners to work from home. As a result, people didn’t use their cars often.

Leaving your car sited for a long time can drain the battery. Although you may cut down on fuel and maintenance costs, your battery is at risk of damage.

But how does a car battery get drained when it’s not in use? Even though your car may be in one place for a long time, the battery continues to serve the alarm system, among other components found in the electrical system.

Extreme temperatures will also drain your car’s battery. In particular, high temperatures make the battery lose charge quickly.

So, when parking your vehicle, always look for a shady spot. Otherwise, your car battery will be more susceptible to damage.

How long does a car battery last without driving?

On average, your car battery can survive for a month when the car is left in one spot. Of course, this time varies based on several factors.

Some of these factors include the type and age of the battery. In addition, the type of electrical components you have in your will also determine the lifespan of your battery.

Leaving your car sited for a long period does not allow it to charge. At this time, the alternator is not on; hence it cannot charge the battery. Subsequently, you are likely to have a bad car battery.

So, ensure you take your car for drives frequently. Most new car battery models can last for approximately three years when maintained properly.

Also, your battery will last this long only when you drive it regularly.

Fortunately, you can use a portable car battery. Portable car batteries work better with cars that are left sited for long periods.

It is possible to charge a mobile car battery separately. So, even though your vehicle may be sited for a long time, you can always remove the battery and charge it on its own.

Besides, the battery is not inside the car. Therefore, the electronic system in the car will not drain the battery. A disconnected car battery can last up to six months if stored and maintained properly. Therefore, it is important to keep your battery charged at all times.

How to store a car battery

At times, you may have no choice but to leave your car immobile for a long time. In such a scenario, ensure you store the car battery properly.

It would be best if you removed the battery from the car and store it separately. Return it only when you plan to use the car.

Doing this will help you prolong the lifespan of your battery. Moreover, it puts the battery in a better position to retain charge. Below are some of the best storage techniques that can help you extend the lifespan of your battery.

How do you store a car battery?

The first thing to do before storing a car battery is to ensure you fully charge the battery. Storing your battery at full charge prevents damage and wearing out of the battery.

After charging the battery, examine the battery to check for any signs of damage. If you notice any problem with your battery, fix it immediately.

Keep in mind that the earlier you fix the problem, the better. Check for any signs of corrosion; corrosion usually appears like a thick blue film on the surface of the battery.

Also, check the battery for any signs of corrosion. If your battery is worn out beyond repair, it is advisable to replace it.

After fixing all the problems in the battery, ensure you clean it. More often than not, batteries experience corrosion on the positive terminal.

Cleaning the battery can help prevent battery corrosion. Use baking soda solution and a soft toothbrush to scrub the exterior surface of the battery gently.

Grime usually interferes with the terminals, which in turn lowers the efficiency of the battery. After cleaning the battery, ensure you leave it to dry.

Use a clean, dry cloth to eliminate all moisture from the battery. Never store the battery when it’s still wet.

Find the right storage location

After drying your car battery, choose the perfect storage location. Extreme temperatures significantly affect the lifespan of the battery.

Typically, heat lowers the charge retention of the battery. Therefore, ensure the storage area receives sufficient aeration.

The temperatures of the storage room should vary between 40 to 60 degrees Fahrenheit. Places that are too hot or too cold make the battery discharge faster.

Additionally, avoid storing the battery in damp places. Damp areas can lead to battery corrosion.

Recharge the battery regularly

Storing the battery is not the end. You have to keep monitoring the battery from time to time. Keeping track of your battery will help you boost its durability.

Check your battery at least once a month. But the more you monitor the battery, the better. If you can, test the voltage using a voltmeter to see the amount of charge in your battery. A voltmeter helps you know the best time to charge your battery.

What to do if your battery is dead?

As mentioned earlier, leaving your car sited for a long period can lead to a failed battery. If you ever experience a dead car battery, jump-start the car. Doing this will get the car going once again.

Nevertheless, jump-starting the car may not work at times. If this happens, consider replacing the car. Also, examine the alternator to confirm if it’s in good condition.

It would be best to employ a professional car mechanic to evaluate both your battery and the alternator.

Conclusion

At the end of the day, it’s all about keeping the battery in good condition. Consult a professional on the best car battery maintenance tips to incorporate.

A healthy battery keeps your car in good shape. Some ways you can maintain your battery include switching off your headlights, dashboard lights and going for long drives.
