Question Winter storage, battery question

For 3 months storage with no electric available, is it best to dis-connect the battery or just leave it connected after giving it a full charge and hope it makes it through the 3 months? Why can't one just dis-connect the battery? I have the radio code.

you can disco it but depending on the batt it still may not hold a full charge. if you can leave the front trunk [fronk] ajar it will help you if you need to remove or jump the batt

The main issue with disconnecting the battery is the ECU will reset to factory default, meaning all the driving history will be lost. This is not a big problem, as the unit will relearn most it needs in a week or two of varied driving conditions. Just don't take the car for emissions testing before all stages are ready, as you will not pass.

If I had to store my car for 3 months

with no electricity available at the storage site I'd:

- Remove the battery from the car
- Leave the front hood ajar so you don't need any electricity to get back in but tape up with blue painters tape the opening (and the side vents, exhaust, etc.)
- Take the battery to a site that had electricity and connect a battery maintainer to it.

At the end of the storage, I'd deliver the battery, reinstall it, remove all the tape and the car and battery ought to be good to go.

Batteries don't like to be stored with no activity for that long. The maintainer will continue minimal activity to keep the battery fresh.

Stabul in the gas tank. Fresh oil. Pull the battery just after the car cools from a long run.
