Hey All,
I'm going away for 3 weeks and car will be garaged (UK 530i, late 2003 model).
I've read quite a bit of stuff about all sorts of weird things happening when battery goes low, and some really scary things as well- is there anything i can do to prevent any idrive mishaps and issues when i return?

My battery's OK, never had any problems with it yet, although I have had low batt warning a couple times when playing stereo for a while with engine off....

Unfortunately I have no-one to start it while I'm away...well, actually, I do, but I would risk a dead idrive than have someone else drive my car

Many thanks in advance for your wisdom.

No problem Traveller.

Three weeks is nothing if your battery is in order.

But a 5 year old battery is beginning to be on the limits.


PS. Where is Middle Earth?

i would disconnect the battery compleatly if its in a garage, and re connect when you get back, saves any alarm going off issues for nehbours.
but if your battery is ok, then 3 weeks is fine as our cars have a "sleep" mode where it shuts down almost everything.

Thumbs down

I suggest a trickle charger too - especially if the car will be stored in an extremely cold or extremely hot climate. Most have an auto-off to prevent overcharging.

It should be connected directly to the battery terminals or the + battery post under the bonnet/hood.

I have heard where some people plugged chargers into their cigar / cigarette / 12v aux sockets in car and didn't realize when the car is OFF those 12v sockets are not powered and the battery cannot be maintained thru those connections!

Whatever you do, but DO NOT DISCONNECT the battery!

If you're a bit doubtful, buy a new OEM battery.
They are not that expensive.

I was gone for almost 5 weeks and just locked the car when I left. I never had any problem when I came back.

Thanks for your replies,

although bit unclear about the battery disconnect / don't disconnect issue...

About the trickle charger, can it just go straight on, i.e with the battery connected?
