Does Idling Car Drain Battery. If I disconnect the positive lead from the battery and only the neg is connected the next day I have a drained battery. If so it drains the battery quickly in the heart.
After the battery has been recharged the battery should also be tested to see if it is. But what is the deal with people who claim that idling their car drains their car battery. If the alternator has problems it will have minimal charge to no charge at.
I usually change my car battery every 3 years.
Keep in mind there are a lot of Prius taxis out there idling all the time. Idling does not allow your battery to charge and causes it to strain. That seems like a tiny amount but a single incandescent dome light pulls enough power to drain a battery in one day. In a normal situation leaving your car idle can charge your car battery.
