Why Battery Parameters are Important. Batteries are an essential part of energy storage and delivery systems in engineering and technological applications. Understanding and analyzing the variables that define a battery''s behavior and performance is essential to ensuring that batteries operate dependably and effectively in these applications.
Energy density. Energy density is often used to compare different energy storage technologies. This parameter relates the storage capacity to the size or the mass of the system, essentially showing how much energy (Wh) can be stored per unit cell, unit mass (kg), or unit volume (liter) of the material or device.
