Hioki BT3554 - Battery Tester Quick Guide; Lets Start by Measuring a New Battery; Example: Changes in Internal Resistance and Voltage

Let's Start by Measuring a New Battery
To determine if a battery is worn out, measure the data of a new
battery. As a battery wears out, its internal resistance increases to
approximately 1.5 to 2 times (reference value) that of a new one.
Use these values as guidelines when determining the battery wear
judgment values.
Example: Changes in the internal resistance and voltage
due to battery wear
New battery
Internal resistance: 0.5 m
ȍ
Voltage: 2.0 V
(The above values are examples.)
Battery requiring replacement
1.0 m
ȍ
(twice the value of a
new battery)
1.8 V (90% of the value of a
new battery)
