There are all sorts of reasons, but the most common are:

a car being left unused for a while, or only used for short journeys

a light being left on

a faulty component

a problem with the car’s charging system

a fault with the battery itself

Batteries can fail for other reasons too. Excessive vibration, over-charging, corrosion and extreme heat or extreme cold.
