PostPosted: Fri Jun 01, 2018 12:52 am    Post subject: Battery Drain When Parked Reply with quote

Looking for some advice.

Some times I have to Park my car up outside for extended periods (2 to 3 weeks) without any use.

A trickle charger is NOT an option and I don't want to come back to a flat battery.

Would disconnecting the battery have any negative effects as obviously disconnecting would perserve battery life.

Thanks for any help offered?

Should be fine if you have a decent battery. I use Bosch S5 with no problems.

Steve997, your like me! There are times for a period of a few weeks I done get to drive my car as I have a company car to abuse and not only that when I get back from work late as normal I don't relish the idea of going back out to drive. So the 997 is a weekend car unless summer and me taking holidays. What I do is I disconnect the battery when not using, the good side of it is the battery always starts the car, the downside of it my Alpine stereo resets but that don't bother me as a few mins it takes I tap in the settings.

Just disconnect battery when not using, been doing it for two years and no problem!

just don't shut the bonnet or hope a passer by doesn't see it open and shut it


this handy device might be a wise investment,

car battery pack the size of an iPhone which will also charge your phone / iPad etc

I've been doing this for a while as I have a drain on my battery and will go flat after ~2 weeks. It's annoying, as I can leave the BMW 1 Series for a month at a time and it'll still start up straight away.. !

What happens if someone shuts the bonnet with the battery disconnected?

Is there a manual cable bonnet release?

Nope. But there is a pull-out terminal in the fusebox that you attach positive jump lead to, negative to anywhere suitable, and then you can operate bonnet release.
