It is a rainy night on the highway, so I open the Lamp and Rain Wiper and drove for 5 hours. When I reached the destination, the battery is fully dead. So I bought a jump starter, and drove for 10 minutes to the supermarket for charging the battery by the car generator. Although the car light resumes, I cannot have enough power from the battery to start the car. How long should I drive to charge the battery so that I can get rid of the jump starter?How long for a car to recharge a discharged battery for normal start?Where to begin....
If the car battery is in good condition and there is nothing wrong with the charging system, ten minutes is enough to get the engine started again. But you already know your charging system is not working - that is why it died in the first place.
The first thing you have to do is get the charging system fixed. The typical problem is that the alternator is bad, but it might be a bad alternator belt or a bad regulator (you don't mention make, model, or year, and some cars have separate regulators). Until the system is charging you will have increasing trouble - soon the jump starter will be dead and so will the car battery.
Then the car battery has to be tested and charged. Deep discharges like that are awfully hard on the battery. If it is just a year or two old it will just have a shorter life, if it is several years old it may not survive this episode. And if the battery is okay, it is vital to charge it with a battery charger and not the car charging system. The new alternator may not survive trying to completely recharge the battery, and if it does its life expectancy will be reduced drastically.How long for a car to recharge a discharged battery for normal start?HARD TO SAY I WOUULD EITHER BY A BATTERY CHARGER AND RECHARGE IT OR TAKE TO CHOP AND HAVE IT RECHARGED CUS DRIVING IT IN NOT GOING TO RECHARGE ENOUGH SINCE UR DRAINING AND CHARGING TOGETHER
