State of Health (SOH): SOH is a measurement that depicts a battery''s overall health and how long it has left to live in comparison to a brand-new battery. It considers elements including the number of cycles, capacity fading, and changes in internal resistance.
This method is useful for accurately measuring battery capacity without the need for discharging the battery. However, it requires specialized equipment, such as a spectro, to perform the measurements. Factors Influencing Battery Performance When it comes to measuring battery capacity, several factors can influence battery performance.
