How Long Does A Car Battery Last Without Driving?

There is no question that a car battery will last longer if you drive the car regularly. But do you know How Long Does A Car Battery Last Without Driving? How often should I charge my battery? And how do I know when to replace it? These are all common questions for drivers, and we’ll answer them in this blog post.

The AA recommends that you should start your car once a week to recharge the 12V battery. This will ensure that it is in good condition and can last at least two weeks without needing any attention from you, but if for some reason it’s not driving regularly, then they advise doing so just as often.

Driving your car can be a drain on the battery, so it’s important to look after it once you’ve stopped driving. It is also important to keep the terminals clean and corrosion-free, as this will stop any power from flowing properly.

If you’re not sure whether your battery is still in good condition, you can take it to a specialist or test it yourself. The best way to test your battery is with a hydrometer, which will tell you the state of your battery’s charge.

How Often Should I Start My Car If I’m Not Driving It?

If your car is old, you should start your car at least once a week, and you should keep the engine running for 15 minutes every two weeks. By doing this, the battery will stay charged and keep the wear on components like belts or hoses from occurring too quickly.

If you have a newer car, you should start your car once a month and keep the engine running for five minutes. This will help to maintain the battery charge, but it will also keep the fuel system working.

You need to know about your car battery because it’s not designed for deep discharges. This can reduce the lifespan of a lead-acid cell by up to 30% if repeated often enough.

In order to avoid this problem, make sure there are no lights on when doing so and also turn off any fans or other automatic devices in case they weren’t already turned beforehand because these might cause sparks during operation, which would increase the risk even further.

What Can I Do To Prolong The Life Of My Car Battery?

There are a few things you can do to prolong the life of your car battery:

  1. Keep the terminals clean and corrosion-free.
  2. Make sure your engine is running every once in a while.
  3. You should not leave your lights on when you aren’t using them.
  4. Don’t turn the heat on high when it’s not necessary.
  5. Don’t leave the radio on when you’re not in your car.

Charging Your Car Battery: Myths and Facts

There are a lot of myths about charging car batteries, so we’re going to dispel some of those myths and give you the facts.

  • One myth is that you should wait until the battery is completely dead before charging it. This isn’t true. In fact, if you do this, then you could damage the battery permanently. Instead, you should charge the battery as soon as possible after it dies or even when it’s just low on power.
  • Another myth is that you should only use the car battery when it’s at 50% power. This isn’t true either. In fact, letting your battery go below 50% can cause permanent damage, so it’s best to charge the battery before this happens.
  • Another myth is that you should only use a specific type of charger for your car battery. This isn’t true. Any good-quality automotive battery charger will work just fine.
  • Finally, one myth is that you should never charge your battery if it’s wet. This isn’t true. In fact, you can and should charge a wet battery as long as you take some safety precautions.

What Should I Do If My Battery Is Flat?

If your battery is flat, you should try to charge it before driving. If that’s not possible, then you’re going to have to get a jump start.

Step By Step Guide For Jump Start A Car

To do this, you’ll need another car with a working battery and some jumper cables.

  • Ensure both cars are turned off, connect the positive terminal of the flat battery to the red cable, and connect the other end to a clean metal part under the hood.
  • Next, connect one end of the black cable to the negative terminal on the good battery and the other end to a piece of metal on the car with the flat battery.
  • Now, start the good car and let it run for a few minutes. Once it’s started, try to start the car with a flat battery. If it starts, then drive it to a mechanic and have them look at the battery. If it doesn’t start, turn off both engines and try again.
  • Finally, you should disconnect the cables in reverse order to avoid any damage or sparks. It’s also a good idea to wait fifteen minutes before trying again.

Steps To Charging Your Car Battery

To charge your car battery, you need an automotive battery charger.

  • First, make sure the area around and under the hood of both cars is well-ventilated.
  • Next, connect the positive end of your charger to the positive terminal on the car battery and then do the same for the negative end.
  • Make sure the charger is set to 12 volts and start charging the battery.
  • Once the battery is charged, disconnect it in reverse order and wait at least 15 minutes before trying again.


A car battery will last for different lengths of time based on how it’s used and the type of battery you own. If your vehicle sits in the garage most days without being driven, then your mileage can be significantly less than if your car gets regular use for a week or two.

The best way to know what kind of life span you should expect out of your current battery is by visiting an automotive service center near you. Now this concludes our article about How Long Does A Car Battery Last Without Driving?

Frequently Asked Questions

When a car battery sits for too long, can it go bad?

Yes. Batteries do not like to sit too long, so the older they get, the more dramatic this will have on their lives. If you buy a car battery and use it for six months before switching it out with another one, then the degradation in performance will be very noticeable after that 6 month period of time.

How long can a car sit without driving?

A car can sit without driving for a certain amount of time, depending on the make and model. Most new cars will hold up well to sitting about four months without driving, but don’t just rely on the numbers.
A used car may need some work before it starts again after sitting around as long as new cars can go with no problems. So always consult your owner’s manual before considering leaving your car idle for such a lengthy period of time.

What is the average battery life?

Some cars have a 12-volt battery, but many more expensive vehicles and luxury vehicles use 24 volts. Car batteries will typically last 4 to 5 years or longer on average, given typical driving distances and climate control usage. But this varies according to the make and model of the car as well as utilization of electronics.
