still no answer to my question?

you know, not everyone can get electricity at a storage place and I'm quite positive the battery will be dead after 3 months if not disconnected.

 

Well, you got a lot of anwers that have no relation to your inquiry. Typical.

Pull the rear covers in the back.

Disconnect and pull the battery. Charge it now and then during that time.

You will have to use the key to open the car, then crawl to the back to reinstall the battery (hopefully kept charged).

Start it and drive off.

Simple.

 

Just take the battery out and take it with you! Put it back in when your ready to drive it!
