Preventing a dead battery when keeping a car parked due to Covid-19
Due to Covid, we have "parked" one of our cars to save on insurance. Because of this, I am unable to drive that car. It sits in our garage. I have been starting the engine and pulling it out to the driveway every few weeks, but 2 weeks ago the car would not start due to not enough juice. I jump started it with my other car and let it run for 5 minutes. Unfortunately, 2 weeks later the battery is again not able to provide enough current to start the car.
What can I do to prevent this? I read that starting the car regularly will actually drain the battery more and that the alternator will not actually charge the car unless it's doing at least 1000 rpm. Since we can not drive the car due to lack of insurance what are your recommendations?
