A battery provides DC (Direct Current) output. This means the flow of electric charge is in one direction, from the positive to the negative terminal of the battery.
In contrast, AC (Alternating Current) changes direction periodically, which is what you get from power outlets in your home. So, whenever you're using a battery, whether in your phone, laptop, or flashlight, you're using DC power.
