I'm going out of the country, and the garage in which my car sits doesn't have an electrical outlet, taking the negative terminal out seems simple enough. My question is that if I do remove the negative terminal, effectively disconnecting my battery, are there any long-term ramifications? I'll be gone for 4.5 months. Thanks

No electrical outlet near by...

OP, there shouldn't be any long term effects but I can't say for sure.

Do you have an LCI? Some of those trunks don't have a key slot. So make sure you either put your seats down or have some other way of getting into the trunk after disconnecting the battery.

Sounds good. Thanks. I have a portable battery booster pack so I figure I can connect that to the terminal under my hood, providing enough juice to pop open the trunk.

I remember someone who couldn't do that and they had to find the wires going to the trunk latch and put 12v on it.

I would check before just to be safe.

I can't think of any serious consequences.You'll probably lose various settings (seat memory,radio presets,etc) and the transmission might have to "re-learn" your driving style (having lost *its* settings) but getting into the car won't be a problem with the little key in your keyfob.My "d" had a key slot hidden underneath...I'd wager that all '09 3's have one (but can't be 100% sure).

Have you considered removing the battery and hooking it up to a battery tender?

trickle charger is the best

I have a float charger on mine now. Last year, it sat for close to five months with no charger. Everything worked fine. You will find mixed opinions on here, but I think five months will be ok.

No, my understanding is they are the worst. No need for them anymore with tenders.

No you will lose some adaptations like throttle, maybe knock, octane, etc

But the seat and radio presets are stored in the key fob.

You will lose date and time and trip info though.

Does not work, been tried before. best is to fold down your rear seats, get from the back seat and pull the emergency trunk handle
