Will battery get charged when car is sitting idle, or you have to get it onto highway?
Battery died and had to jump start the car. Now have a question about charging the battery.
Normally I will drive my car on the highway for a while to charge the battery, but it is snowing outside and I am thinking if it is possible to charge the battery other than running on the highway? So
1. If you park your car in your garage and jump start it, then let the engine run for a while (say, half an hour or longer). Will it charge the battery? Or you have to get the car onto the highway?
2. If the alternator does charge the battery when the car is sitting idle, is it better to sit in the car and step on the gas pedal so that it charges faster?
3. Is there any other method if you do not want to bring your car onto the highway to charge the empty battery?
Thanks.
