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.

Example: Changes in the internal resistance and voltage
due to battery wear

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.

Association 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) lead-acid batteries and alkaline lead-acid batteries,
variations in internal resistance are small compared with sealed
stationary lead-acid batteries, and sometimes it is difcult to
determine worn out state of the batteries.

Features

1.3 Features

Enables measurement without shutting down UPS

systems

This instrument uses high-precision AC resistance measurement
technology, and noise reduction technology. Time required for
measurement is reduced since the instrument is capable of
measuring live wires without requiring the UPS system to be shut

down.

Reliable measurement values

This instrument is capable of obtaining reliable measurement values
without being affected by lead or connector resistance because it
uses the AC 4-terminal method to measure internal resistance.

Simultaneous display of resistance, voltage, and

temperature

Without changing functions, this instrument can display
battery internal resistance, voltage, and terminal temperature
simultaneously. Temperature measurement requires the optional
model 9460 Clip Type Lead with Temperature Sensor.

Comparator function

The comparator function enables you to set threshold values for
internal resistance and voltage. This can determine battery wear
more easily.

Large memory capacity

This instrument can store up to 6000 sets of data combining
presently measured values (resistance, voltage, temperature, and
comparator measurement results). It can be used to measure up to
12 units of 500-cell cubicles.

Measurement

3

To ensure safe operation, be sure to read "Operating Precautions" (p.

11) 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 insufcient ow of current for measurement. In such a case,

clean the terminal (remove the insulation) before measurement.

Adjusting Zero Value (Zero Adjustment)

• Keep the zero adjustment board at least 10 centimeters away
from the instrument.

• Be sure to use the included 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.
