Can I Leave The Battery Out Of My Car For The Winter?

I have a 2011 Buick Lacrosse, it has the push button start to it, just a fob you keep with you to start it. I have seen post when replacing the battery last fall that if left out to long will effect the computer, and being it dont take a key really dont want that. I am parking the car in my garage for the winter and want to take the battery out so I can hook it up and keep it charged all winter until next spring, and will once in a while go start the car. I dont have power to my garage and just ran a cord out there last winter and worked out good, but want to avoid running cords out this winter.

Would taking the battery out for probably 2 weeks at a time be a good idea? I try to start once a week and drive about once a month during winter, but winters get cold here, and I replaced a couple batteries last winter on cars used daily it got so cold, so would like to keep battery safe.

    I would connect a trickle charger like this one 981 and use fuel stabilize

    Use a solar charger. Harbor Freight Tools sells them for about $20. It will keep the battery topped up and no more than that is needed.

    I left the battery hooked up in my car for 2 years and never started the motor. Snow winters. When I got my license back, started the car like normal.  My car was 07 so an older technology battery than 2011.

    . leave the battery alone. The cold won't hurt it, or there would be MANY stranded cars up at the ski hills (& yet there are none).

    .   A battery is like a cup of coffee. The liquid is the charge of the all the accessories are "sipping coffee from the top, so not much power is taken away.   A starter motor is Like a BIG GULP of coffee, so much power is taken away and the charging system replaces the power with little peestream going into the battery.  So, unless you were planning a 200 mile trip @ 60MPH, you won't replace the power taken out from activating the starter the battery will not be fully charged.  Idling excessively will not charge the battery.

    . Removing the battery; just mucks up the computer because you killed the power.

    "I replaced a couple batteries last winter on cars used daily it got so cold,"

    Yeah, that happens for 2 reasons.  The cool weather puts more strain on the battery   AND

    Batteries AGE.  Average N.A. battery lasts about 7 years then it is history, though the battery warranty is for 72 months(or 6 years) so they were like old men trying to turn the motor over and they DIED.  Basically it is human nature not to change something that still works fine but come Nov. or the first snowfall the old batteries show their age. 

    . People wait until the car battery starts to die before they shell out money for another battery. Which is the colder months.  Nothing you can do to stop aging.

    . In 7 years time those same cars will have the same battery problems AGAIN.

    I would simply run AC power to the garage. Lets you use power tools when working.

    Why not just have two batteries. You can keep one charged up for emergencies.
