State of Health (SoH)

The State of Health measures battery degradation and remaining capacity relative to its new state, providing a quantifiable value for how much a battery has aged. It is typically represented as a percentage, with 100% indicating a brand-new, perfect battery, and lower percentages indicating reduced storage capacity and power delivery due to factors such as cycle count, temperature, and age. SoH can help predict a battery’s life expectancy and when it may need to be replaced.
