resistance of a new or good battery, and decide the limits for judging
battery wear.
As a battery wears out, its internal resistance increases to
approximately 1.5 to 2 times
(reference value) that of a new or
good battery, and voltage values decreases to 90% of the default
value. Use these values as guidelines when determining the battery
wear judgment values.
Example of the battery wear judgment values

The above values are examples.
The above values vary depending on the manufacturer and
battery model. For more information, see "1.1 Measuring Battery
Wear" (p. 19).
