You want to learn how long car batteries can sit unused right?
Well!!! Most machines need to work to remain okay. It’s no surprise that they’ll stop working if they’re not used regularly and car batteries are no exception. Although they’re an integral part of our car, they can get out of order if not taken care of seriously.
Many times, our cars remain unused for weeks, often months. This can be due to our absence from our vehicles, long trips, or natural calamities happening around us.
While it might seem harmless, not using our vehicles for too long can often damage our car batteries and might require an expensive replacement.
In this article, we’ve discussed multiple factors of car batteries and how long car batteries can sit unused based on their technical aspects.
Uses of a car battery when a car is not in use:
A question might arise that why does your car require battery even when it’s not being used. It’s because the car has multiple features that require power.
The climate controls, the monitors, stereo, radio, music system, memory-foam for the seats, everything requires some energy for it to remain stable.
Therefore, your car constantly requires power to function in a proper manner.
Although battery life depends on the type of battery, power, type of vehicle, and age of the battery, we can determine an approximate lifetime for the battery.
Calculating the battery percentage:
Our batteries have n hourly capacity, divide that by 3.33 and you’ll find the minimum power at which it’ll work. Then, divide it by 0.01 and you’ll find the number of hours it will run without use.
Suppose, you have a battery that has a 100A/h capacity, then divide it by 3.33 which is 30.03, subtracts it from the original that is 100A/h and you get 69.68A/h. Divide that by 0.01 and you get the number of hours it will run without use.
In our case which is 6968 hours. Which roughly equates to 290 days.
While this can give us an idea, it’s not an accurate value. Mostly because when unused, cars spend their energy in their internal parts as stated above, and thus it also depends on the car and the battery.
But on average, a car battery can stay in good condition for about two weeks to two months based on the car and other relevant factors. However, there are a number of ways we can make sure it stays in good condition for a longer time.
Taking care of the car battery inside the car:
The safer option to store a car battery is by keeping it inside the car. In this way, the battery remains in a safe place, doesn’t get damaged easily, and can be checked every now and then.
The best way to make sure your battery stays in good condition is by starting the car once every three-four days and keeping it turned on for at least 15 minutes.
However, only turning it on won’t do you a favor, because you need to make sure it reaches at least 10RPM and stays that way for some time. In that way, otherwise, it won’t charge and you’ll only waste time and battery life.
This is very important to keep in mind that the battery needs to reach at least 1000 RPM before it starts to recharge properly. For that, you can also drive around the yard and get your vehicle some velocity
Using a Smart Charger:
Also, if you’re willing to spend some money, you can buy a smart charger and get your car charged once every week. The benefit from it is that a smart charger does not overcharge your car and do more damage.
Rather, it stops charging once the battery has an optimum charge. This is a relatively safer option if you don’t have the option to drive outside.
Also, sometimes batteries spend a very long time on shelves and thus lose some charge when put in use immediately. So, you can get it tested and charge it using a smart charger before starting to ride with the car. ‘
Storing the Battery Outside the Car:
However, if you plan to not use your car for a very long time. For example, you might want to keep it indoors for winter and take it out during spring.
This change of temperatures can affect your car battery in a lot of ways, especially if you live in a region where winters are harsh. In that case, removing your battery and keeping it in a warm place is a good idea.
Remember, removing a battery is not an easy task, you need good technical knowledge about cars and other relevant hardware to do it successfully. There are multiple terminals, sockets, power points, etc. that need to be dealt with. So, do seek professional advice if working with such tools is not your forte.
One important advice in storing a battery is to make sure it doesn’t attract moisture. Keep a piece of plastic or moisture absorbing mat under the battery so that it doesn’t get wet or moist. Furthermore, make sure you keep it in a cool place, away from direct sunrise and the reach of children or pets.
Even if you have your battery removed, make sure to get it charged. Use your charger to get it charged every once in a while and don’t spend too many days without charging it. If it stays idle for too long, it will start losing power.
Also, clean it with some water and baking soda once every 2-3 weeks to make sure it doesn’t accumulate dirt.
Car batteries can last a good five to seven years if used with care. However, most of the time we damage them by not using them properly, especially when they’re not in use.
But, a bit of consciousness and some tricks can give your battery a very long life. In this article, we’ve presented ways to preserve a car battery when it is not in use and we hope you find this useful.
Finally, We believe that this article has helped you to teach how long car batteries can sit unused.
