If you’re in the market for a new battery or simply curious about the types of batteries available, you may have come across the term “energy density” before. Energy density is a measure of how much energy a battery can store per unit of weight or volume. The higher the energy density, the more power the battery can provide for its size.
Batteries with high power density are used for power tools, medical devices and transportation systems. An analogy between energy and power densities can be made with a water bottle. The size of the bottle is the energy density, while the opening denotes the power density.

Energy Density and Power Density: The quantity of energy stored per unit of mass or volume is measured by the energy density (Wh/kg or Wh/L). How much power can be delivered per unit of mass or volume is indicated by the power density (W/kg or W/L). In particular, these factors are crucial for portable and mobile apps.
The energy density of AA batteries varies depending on the type of battery. Alkaline AA batteries, which are the most common type of AA battery, have an energy density of around 100-150 Wh/kg.
