How long can a car sit before the battery dies?

Depending on the vehicle, you can let your car sit for months at a time if you plan to have a storage methodology in place. Take a look at what the safe sitting time for a vehicle is.

BMW says Four weeks is the max for storage without removing the battery or putting it on some form of life support or a battery tender. The battery, if removed is good for about six weeks to 6 months. Then you need to have it recharged.

However, to be on the safe side a battery tender is your best option with the battery removed if you are planning to store your car for winter or long-term storage. Ideally, a battery that has been removed otherwise needs to be recharged every 12 weeks.

You can, of course, prepare your car before hand and then you can store it almost indefinitely, as we will show you in the next section.

How to store a car for winter?

Putting your car up for winter is not as simple as just parking in a garage or one of those storage container lots where a lot of America's put their unused goods.

However, having said that it is not rocket science either, it is just a matter of doing things in a logical manner, and your car will be ready to use the following spring no worse the wear in the process.The first thing you need to do is get any outstanding maintenance out of the way.

Fix those little things that you have been putting off, like running lights that are not working, etc.Next, get yourself an oil change to remove and contaminants inside the engine. Take the car out for a spin to let the new oil and filters flush everything out.

Make sure you change out the oil and air filter as well. Just before entering the storage area have the car waxed to protect the finish if you are planning to put a cover on the car.

Next, take your car to the gas station. Have the tires pumped up to 5 PSI over the normal readings you use usually. Have a fuel stabilizer added and then top off the tank. Take your car to its hibernation spot, then seal the vents grill, and if you like to put some mothballs in the exhaust pipe before plugging it.

You might also want to open up some baking soda and put a couple of plastic tubs of the stuff in the front and back seats. Disconnect the battery and remove it to a place where it can be put on a maintainer and finally tape off the windows to seal the insides of the vehicle.

Though, many say you should run it during the winter months. However, unless you are using a heated facility, you might be doing more damage than good by trying to turn over a winter's frozen engine.

Put your car to bed and then wait until spring and it will be ready to go for your spring, summer, and fall driving the next year.
