A discharge curve is a measurement of the reduction in voltage as a electrochemical cell or battery as it is discharged. There are two general types of discharge curves, sloping and flat. Flat discharge curves are typically seen with spiral-wound or jelly-roll cell constructions. These cells typically have low internal resistance due to their construction which consists of layers of anode and cathode material wrapped into a jellyroll shape and so can deliver high surge currents. This is the main reason they have flat discharge curves.

The other kind of discharge curve is the sloping discharge curve, typically seen with alkaline batteries and Leclanche cell. Due to the decreased surface area in contact with the typical "bobbin construction" cell, the discharge curve slopes downwards during the entire discharge cycle.
