Okay this might sound weird but I swear my car acts differently after I've been stuck in heavy traffic for a few days in a row. Normally I work from home two days a week so my car gets a break. But last week I had to go to the office every single day and the traffic was absolutely terrible each time. By Thursday, my car was cranking slower than usual in the morning. Not dead, just sluggish. Like the battery was exhausted. I don't know how else to describe it. I mentioned this to a friend who knows more about cars than me and he started explaining the traffic congestion impact on battery health. He said that when you're sitting in slow moving traffic with the engine at idle, the alternator isn't spinning fast enough to fully power all the electronics and charge the battery at the same time. The AC alone draws a huge amount of power. Add the radio, the phone charger, the dash cam if you have one, and the battery is actually losing charge slowly while you sit there. Do that for an hour each way every day and by the end of the week the battery is running at a lower state of charge. That's why my car felt tired on Thursday morning. The battery hadn't fully recovered from the previous days of traffic. That makes so much sense to me now. But here's my question. Is there anything I can do to help my battery recover faster after a week of heavy traffic? Would going for a long drive on the weekend at highway speeds fully recharge it? Or should I buy a small battery charger and hook it up on Friday nights? I don't want to just accept that traffic will slowly kill my battery. There has to be a way to fight back. Anyone else noticed this same pattern with their car after a week of bad traffic? What do you do about it?
