When you require dc source it is preferable to use a dc power supply instead of a battery why?
It depends on where the power source is needed. In portable equipment for starting engines or portable equipment like cordless saws, drills, or lights a battery is the preferred method of power. In indoor stationary charging equipment for portable phones for example a continuous supply of AC power being converted to DC is more convenient than have batteries around the home that have to be charged when running low on voltage.
