639 views

When i leave my car parked and off for more than a month i often have to charge/replace the battery. However when i disconnect the battery it somehow lasts way longer. I cant think of anything that is on all the time when my car is parked (no alarms, remotes)

I had a car that did that. Took forever to find problem. Turned out that there was a problem with the switch for the small light in the trunk. The light always stayed on even when trunk was closed. Therefore a constant drain on battery.
