Reply to comment by superseriousaccount5 in LPT: After every mechanic visit, drive your vehicle around for 10 to 15 minutes extra before going back home. by TheMasterBaker01

I've heard it's about 30 minutes for a good alternator running solid on the highway. 2 hours or more just driving on small roads.

Highway or small roads dont make a big difference these days with virable alternators. They will change depending on your speeds. If you are trying to charge a battery from dead, you need to put it on a charger. If its sat with the door open for a couple minutes, driving from your house to the grocery store will be fine

It was dead the next morning. It needs a lot more than meandering for 15 minutes.

If worried, turn off all possible electrical and run the speed up. I keep a charger at home for all that though

If you can start a car, drive home and next day battery is dead, your battery is just bad.

This seems to be a lost idea on this LPT. Its mind blowing how many people know so little about cars but keep speaking like the mechanics are the ones in the wrong
