Hello all,
My 545 is inside a heated garage. I have noticed that after 7-10 days of not starting it, the car feels just a bit strained to turn over. The battery is 2 years old and I have already replaced dthe alternator and tested the voltage. All is fine with the charging system. I know these cars draw a lot of power , even not driven.
i am going on a trip for 3 weeks. If I disconnect the IBS for that period of time, do you guys think I will retain more of a charge when I come back?

After a drive let the car sit idle at least 1/2 hour and then measure the voltage of the battery before starting. 12.6V+ is a healthy fully charged battery. 12.4V is about 75%, with 12.2V about 50%.

The IBS failure is really not all that common. What is more common is that the battery starts to lose its ability to hold a charge (yes, even after only 2 years). Rather than a healthy battery being able to sit idle 20-25 days at a regular closed circuit current (the amount of power that the car draws at rest with all systems off), a reduced capacity battery at 10 days is starting to get on the ragged edge.
