For example: Tesla cars choos. This is the amount of energy the battery can store. Higher capacity means the battery can store more energy and provide more operating time for the device. The voltage and current of a battery determine the amount of power it can deliver. For the same current, higher voltage can provide more power to the device. Energy density is a measure of how much energy can be stored in a given volume or mass of the battery. The cell with high energy density will be more compact and lighter, but it may also have a shorter lifetime and may. This is the rate at which a battery can discharge its stored energy. It determines how quickly it can deliver its stored energy. For example: If the battery capacity is 1Ah, 1C is 1A discharge 1h to complete the discharge, 5C is.
