how long does your battery hold a charge?
I have a SMG M3 that seems to drain the battery a little. How long does your battery hold a charge without being driven?
The battery was replaced in June. I replaced it again under warranty again this week. I tested the power draw. It is pulling 50-60 milli Amp. I think this is acceptable power draw right? I wonder if the previous battery is bad. The current battery seems to hold enough power to start the car after sitting 5 days (so far). Thanks! |

My car started right up after 13 days of sitting. I have a Duralast AGM battery.
