Let’s start by measuring a fresh battery
To evaluate whether batteries have deteriorated, measure the
internal resistance of a fresh battery. Deteriorated batteries will have
about 1.5 to 2 times (values for reference purposes) as high internal
resistance as a fresh one. Use these values as guidelines when
determining deterioration evaluation values.
Example: Changes in the internal resistance and voltage
associated with battery deterioration
Internal resistance: 0.5 m
