Battery Tester Quick Guide
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.

Overview
1.1 Measuring Battery Wear
IMPORTANT
To determine if a battery is worn out, rst measure the internal
resistance of a new or good battery.
When the battery is worn out, the internal resistance rises to
approximately 1.5 to 2 times its default value (reference values).
The graph below shows the relation between storage capacity and
default value of internal resistance in a lead-acid battery. "CS",
"HS", and "MSE" denote JIS (Japanese Industrial Standard) leadacid battery types.
The internal resistance of an MSE (sealed stationary lead-acid
battery) can be read at approximately 1 m

Measuring Battery Wear
• The warning limit (WARNING) for an MSE (sealed stationary
lead-acid battery) is when the internal resistance reaches
approximately 1.5 times its default value. The failure limit (FAIL)
varies for each manufacturer.
• Default value of internal resistance may vary among batteries
with the same capacity, depending on the model or manufacturer.
Use the graph on the previous page as reference.
• Internal resistance warning limit (WARNING) and failure limit
(FAIL) varies for each manufacturer.

of Japan (BAJ)
Comparator function (p. 55)
With the comparator function, the battery measurement values
can be compared with the present threshold values to determine
which ranges those values fall within: PASS, WARNING, or FAIL.
In open (liquid) stationary lead-acid batteries such as CS, HS, and
alkaline lead-acid batteries, variations in internal resistance are
small compared with sealed stationary lead-acid batteries, and
sometimes it is difcult to determine worn out state of the batteries.

Measurement
3
To ensure safe operation, be sure to read "Operating Precautions" (p.
12) before starting the measurements.
• Internal battery resistance varies considerably depending
on charge or discharge status. To increase measurement
accuracy, make measurements under similar conditions (for
example, a fully charged battery).
• Lead-acid batteries (measuring objects) have high levels of
terminal resistance. For this reason, resistance values may
differ between the case and the tip of the terminal. Be sure to
connect the test lead to the terminals at a xed location.
For more information, see "Effects of Current Density" (p. Appx.5).
• Use the optional model 9460 Clip Type Lead with Temperature
Sensor to measure the battery temperature. Or, use a noncontact thermometer, such as a radiation thermometer, for
safety.
• Measurement may not be possible for insulated terminals, due
to insufcient ow of current for measurement. In such a case,
clean the terminal (remove the insulation) before measurement.

3.3 Adjusting Zero Value (Zero Adjustment)
The zero adjustment function displays subsequent measurement
results using the measured value (correction value) obtained when
it was performed as zero.
The dened accuracy does not require zero adjustment to be
performed when using accessory or optional test leads, but the

For more information, see "8 Specications" (p. 89).
• Performing zero adjustment adjusts the zero points of all
ranges.
• Even after the instrument is turned off, the correction values
are retained and the zero adjustment function is not canceled.
• After replacing the test lead, be sure to perform zero adjustment
prior to measurement.
• Be sure to use the included or optional zero adjustment board
when performing zero adjustment.
• Be sure to keep the test lead shorted during zero adjustment.

Adjusting Zero Value (Zero Adjustment)
• Keep the zero adjustment board at least 10 centimeters away
from the instrument.
• Be sure to use the included or optional zero adjustment board
when performing zero adjustment.
• Be sure to connect each of the SOURCE and SENSE terminals
by inserting the tip of the pin into the holes on the zero
adjustment board. (See the gure below.)
SOURCE
SENSE
• Do not place the zero adjustment board on top of the battery
or any metal. Electromagnetic induction effect could result in
unstable measurement values. In such a case, keep the zero
adjustment board away from any metal.
• Performing zero adjustment by connecting the tips of pin-
type leads or using a metal sheet other than the included zero
adjustment board will result in inaccurate adjustment of the
zero point.
• When the distance between the terminals on the battery
(measurement target) is more than the distance between the
holes on the zero adjustment board, use the holes at both
corners to perform zero adjustment.
• Consider the zero adjustment board to be a consumable.
Replacing it with a new one after using it around 700 times is
recommended.

Determining Battery-wear Judgment Values
3.5 Determining Battery-wear Judgment Values
To determine if a battery is worn out, rst measure the internal
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.
