Dead Battery after 5 Days Idle
Hi Team. 2016 3.5i. 12,935 original miles. New battery installed Feb 21 at BMW dealer. Interstate AGM. I bought the car in March of 21. I live in Virginia and temp has been between 50 and 90 F for the last 3 months. The car sits in the garage during the week and sometimes weekends. After about 7 - 9 days I go to start it up and it needs a jump. No other issue other than that. I am taking battery back to Interstate today so they can test it. If that comes back OK, than what else is happening? Why do I need to jump it only after it sitting idle 7-9 days? Thanks in advance.

Is it an option to use a battery conditioner, my zed is hooked up whenever it’s not in use , to date I have no issues and my car sits for weeks , especially during the winter .

+1, a trickle charger hooked up under the bonnet/hood will sort that out.
Saying that a battery that’s a few months old should not be fully discharging in a week unless there’s a drain on it

You must have a circuit draining the battery..either something like a tracker / dash cam / after market blue tooth device..
There was an issue of some car’s Bluetooth module not allowing full shut down ..a software revision fixed that..
A fully battery charged battery should last at least 6 weeks then start ..

As long as you are not in and out of the car waking the system. Let it go to sleep and wake it up when you want to drive it.

So I bought a 35is with all the toys to play with.
