How Long Can a Car Sit Before The Battery Dies?

How long can a car sit before the battery dies? This is one of the most asked questions about cars. Actually this depends on how we use and store it. And a short and simple answer is that a little under 2 months. Today we will discuss this matter in detail.

Cars have clocks, radios, and other things that are constantly draining the battery, even with the automobile off the power. Depending on how old your battery is (older batteries do not last so long) a week is the most I’d want to leave an automobile without being launched. If you were leaving it for longer, a battery, tender/minder trickle charger would be a good thing. You can disconnect the battery life, but that may be a nuisance with newer cars.

There are items in more contemporary cars that have battery power. It is called parasitic drain, things that release your battery without you knowing it. Even the dashboard clock, possibly the radio, and the engine will use just tiny electricity daily.

A lead-acid battery will DIE (like in be killed) when you keep pulling power when it has been discharged. The battery chemistry is ruined permanently if you leave the lights on for days, by injury.

If you know you’re not likely to use a vehicle, there are several small solar panel charger options that plug into the cigarette lighter outlet and will burn the battery so that it won’t die (literally) if the parasitic drain keeps pulling power from a discharged battery.

If your car is in the garage and not going to be used for a while, you can attach a battery maintainer to the battery to add a little power to the battery every so often. This assumes you have AC power near the car to run the battery maintainer. A battery maintainer is a low power battery charger that will check the battery voltage every so often and will top it off if needed. It won’t overcharge a battery like a traditional charger can.

Depending on the car, you can let your car sit for weeks at a time if you intend to get a storage plan set up. Look at what the safe sitting time for a car is. If you really want to know how long can a car sit before the battery dies? There is a basic solution already given above.

BMW says Four weeks is the max for storage without removing the battery, putting it on some life service, or a battery tender. The battery, if eliminated, is perfect for about six weeks to 6 weeks. Then you want to get it recharged.

But to be on the secure side, a battery tender is your best option, with the battery removed if you are planning to keep your car for long-term or winter storage.

When You Can Understand, Your Battery Will Die Soon or Dying

When You Can Understand, Your Battery Will Die Soon or Dying

1. Clicking noise when turning the key: If the engine does not crank in any way, the automobile will often only make a rapid clicking noise, signaling the available power is too low to crank the motor. You may try turning your key as many times as you’d like, you may even leave your car for a bit and return to try again, but the result is going to be the same. If your car will not start and everything you hear is a clicking sound, your battery is almost or dead.

2. Issues with electric parts: Most modern cars have many electronic accessories, including power seats, power windows, radio, dashboard lights, headlights, windshield wipers, and more. Every one of these things requires the power that comes out of your car’s battery to work. If these elements begin acting up, you need to have your battery checked.

3. Slow Engine Crank: This is probably among the most common signs of a perishing battery. The engine pulls amperage in the battery every time it begins. If your battery is near death, you will probably find your engine slow to crank. If you hear your motor cranking gradually, bring the car in whenever possible. Do not ignore this, or maybe you find yourself in the specific position we described above. If you want to save your car battery, you can use Battery Tender 12 Volt Junior Automatic Battery Charger. It works as a battery guard for your car and a great product that worth money.

4. Dim headlights: The headlights dim when they aren’t receiving the power they need to glow as brightly as they should. If your headlights aren’t as bright as you remember them being before, you may wish to think about having your battery checked.

5. The battery is”old”: The automobile battery usually only lasts around four or five years. The lifespan can fluctuate based on vulnerability to extreme temperatures (hot or cold) and your driving habits. Once your battery reaches the lecture mark, you may want to have it tested to see just how much life it has left. If you’re not sure how old your battery is, the date can frequently be found on the battery situation. But if you can’t find this, and so are still unsure, then you might want to think about having it analyzed.

  1. I really like that you touched on using a battery maintainer to keep the battery fresh while it sits. My brother has a nice car on his property that hasn’t been driven for a while now though. He needs to get it towed to a mechanic soon because it doesn’t seem to be starting properly.
