Discharge Efficiency: This parameter measures the proportion of energy provided by the battery when discharging. Battery type, load, and ambient temperature all have an influence on discharge efficiency. A higher discharge efficiency leads to longer battery life, making your battery serve you well with improved performance.
A higher charge efficiency means your battery will lose less energy every time you charge it, thereby making you have cheaper power expenses. You can use the Coulombic Efficiency (CE), which is the ratio of the actual delivered charge to the battery's theoretical charge capacity, to measure your battery's charge efficiency.
