It is very difficult to charge, unless the engine is maintained at two or three thousand revolutions for a few hours. Therefore, as long as the fire can be ignited the next day, you can charge it little by little as you use the car every day. Generally, keep the engine at about 1500 rpm and charge for half an hour, and leave it overnight to ignite the next day.
