Battery failure or weakness is caused by reduced charge when some electronic devices still have to use a small amount of electricity to maintain operation or the owner forgets to turn off the headlights.

However, with cars that are less active, the generator cannot compensate for the lost charge, so the battery is weak or damaged, leading to the car can not start.
