Battery Tester Quick Guide

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

1.1 Evaluating Battery Deterioration

IMPORTANT
To evaluate whether batteries have deteriorated, rst measure the
internal resistance of a fresh or non-defective battery. If a battery has deteriorated, the internal resistance will increase
by 50 to 100 percent (value for reference purposes) from its initial
value.
The graph below shows the relation between the amount of battery
charge available and the initial value of internal resistance in a lead­acid battery. “CS,” “HS,” and “MSE” denote lead-acid battery types according to Japanese Industrial Standard (JIS). The internal resistance of an MSE (sealed stationary lead-acid battery) can be graphically read at approximately 1 m and approximately 0.13 mΩ (1000 Ah).

Evaluating Battery Deterioration
• For an MSE (sealed stationary lead-acid battery), the warning
threshold (WARNING) of the internal resistance is dened as about 1.5 times its initial value. The rejection value (FAIL) varies depending on the manufacturer.
• Initial values of internal resistance may vary among batteries under measurement with the same capacity, depending on the model or manufacturer. Use the graph on the previous page for
reference purposes.
• Warning thresholds (WARNING) and rejection values (FAIL) of
internal resistance vary depending on the manufacturer.
Source: Battery technician certication textbook, Battery Association
of Japan (BAJ)
The battery measurement values can be compared with the present threshold values using the comparator function to determine the scope in which the values fall
within: PASS, WARNING, or FAIL.
See “4 Comparator Function (Evaluation Based on
Threshold Values)” (p. 67).
Changes in the internal resistance of open (liquid) stationary
lead-acid batteries, including CS and HS, and alkaline lead-acid batteries, may be smaller than sealed lead-acid batteries. Thus, it is sometimes di󰀩cult to determine whether such batteries have been
deteriorated.
22
Evaluating Battery Deterioration
Measuring lithium-ion batteries
The instrument measures internal resistance and voltage of batteries using AC having a frequency of 1 kHz. The internal resistance of lithium-ion batteries can also be measured; however, that of a packed battery will include the protective resistance, which is installed in packed batteries. Besides, the instrument may not be
able to diagnose and evaluate the deterioration of such batteries
because changes in the internal resistance of lithium-ion batteries due to deterioration may be smaller than lead-acid batteries.
23
Overview

1.2 Overview

The instrument measures internal resistance, voltage, and terminal temperature of lead-acid, nickel-cadmium, nickel-hydrogen, and other types of batteries, enabling you to determine if batteries have
deteriorated.
To measure terminal temperature, the 9460 Clip Type Lead with Temperature Sensor (option) is required. To measure an ambient temperature, the 9451/9451S Temperature Probe (option) is required.
After measurement, connecting the instrument to your computer with the accompanying USB cable enables measured data transfer to the computer. Also, you can browse through and record measured data on your smart phone or tablet using the wireless communications function.

The instrument can be populated 100 sets of prole information (comments, such as location information and device information, and the buttery number information). Saving measured data in connection with prole information makes it possible for you to manage measurement locations, UPSs, and batteries easily.
Measurement recording prompt
The instrument and your mobile device with GENNECT Cross installed, using the display and voice prompts, respectively, can inform you of comparison results and the battery number you are to measure next. This enables you to record measured data quickly.
Automatic hold function and automatic memory
function
When these functions are enabled, the instrument can automatically, at the instance when the display freezes measured values, save the measured values in its internal memory. This can lead to increased operational e󰀩ciency.
Measurement without the need for UPS system
shutdown
The instrument uses high-precision AC low-resistance measurement technology and noise reduction technology. Time
26
Features
required for measurement will be reduced since the instrument is capable of measuring live wires without requiring a UPS system
shutdown.
Reliable measured values
The instrument is capable of obtaining reliable measured values without being a󰀨ected by wire resistance of the test lead or contact resistance because it uses the AC four-terminal method to measure internal resistance.
Simultaneous display of resistance, voltage, and
temperature
Without switching functions, the instrument can display battery internal resistance, voltage, and terminal temperature simultaneously. To measure terminal temperature, the 9460 Clip Type Lead with Temperature Sensor (option) is required. To measure an ambient temperature, the 9451/9451S Temperature
Probe (option) is required.
Comparator function
The comparator function enables you to set threshold values
for internal resistance and voltage. This can evaluate whether
batteries have deteriorated more easily.
Computer interface
Measured data can be transferred to your computer.
Wireless communications function
Connecting the Z3210 Wireless Adapter (option) enables you
to browse through and record measured values with your smart
phone and tablet.
You can utilize the measurement recording prompt in sync with your mobile device with GENNECT Cross installed.

Measurement

3
To ensure safe operation, be sure to read “Operating Precautions” (p. 11) before starting the measurements.
• There is a considerable di󰀨erence in the battery’s internal resistances between a full-charge state and a discharge state.
To improve evaluation accuracy, perform measurements under
a constant condition (for example, in a full-charge state).
• Terminals of lead-acid batteries (objects under measurement)
have a high resistance. Thus, resistance values may di󰀨er
between contact locations, the case side and the tip of the terminals. Place the test lead into contact with the terminals at
the same location every time. See “11.4 E󰀨ects of Current Density” (p. 157).
• Use the 9460 Clip Type Lead with Temperature Sensor (option) to measure the temperature of the battery terminals.
Otherwise, use a non-contact thermometer, such as a radiation
thermometer, for safety.
• If terminals are covered with an insulating layer, the measurement current cannot ow su󰀩ciently, resulting in
measurement failure. In such a case, clean the terminals to
remove the insulation layer before measurement.
45
Inspection Before Measurement

3.1 Inspection Before Measurement

Check the instrument for any damage that may have occurred during storage or shipping, and perform functional checks before use. If you nd any damage to the instrument, please contact your authorized Hioki distributor or reseller.

Adjusting the Zero Point (Zero Adjustment)

3.4 Adjusting the Zero Point (Zero Adjustment)

When the zero adjustment function executed, the instrument will
regard the measured values (correction values) as zero to display
subsequent measurement results.
Only if an accessory or optional test lead is used, the instrument can meet the accuracy specications even without executing the
zero adjustment. However, execute the zero adjustment in the following cases:
• When you wish to increase measurement accuracy For the 3 m on whether zero adjustment has been performed.
See “9.3 Accuracy Specications” (p. 123).
• When using a test lead, including Hioki product, that is not an accessory or option of the instrument or whose length has been
extended
IMPORTANT
Use only the Hioki-specied test lead. Hioki does not guarantee the accuracy and proper operation if any test lead not specied by the company is used.
• Performing zero adjustment adjusts the zero points of all ranges.
• Even after the instrument has been turned o󰀨, the correction values will be retained and with the zero adjustment function remaining enabled.
• After replacing the test lead, always perform zero adjustment prior to measurement.
• Always use the included or optional zero-adjustment board when performing zero adjustment.
• Keep the test lead short-circuited during zero adjustment.
• Keep the tips of the test lead away from any metal components.

Adjusting the Zero Point (Zero Adjustment)
• Keep the zero-adjustment board at least 10 cm away from the instrument.
• Always use the accompanying or optional zero-adjustment board when performing zero adjustment.
• Insert the pin tips into the hole on the zero-adjustment board
and place each of the SOURCE and SENSE terminals into contact with the hole on the board. (See the gure below.)
SOURCE
SENSE
• Do not place the zero-adjustment board on top of the battery
or any metal. Electromagnetic induction e󰀨ect could result in unstable measurement values. In such a case, keep the zero­adjustment board away from any metal.
• If zero adjustment is performed with the Pin Type Lead short- circuited at the tips or using a metal sheet other than the zero­adjustment board intended for this purpose, the instrument
cannot adjust the zero point accurately.
• When the distance between the terminals on the battery (target under measurement) is more than that between the holes on the zero-adjustment board, use the outermost holes to perform zero adjustment.
• Consider the zero-adjustment board to be a consumable. It is recommended to replace it with a new one after the use of
around 700 times.

Determining Battery-Deterioration Evaluation Values

3.7 Determining Battery-Deterioration Evaluation Values

To evaluate whether batteries have deteriorated, rst, measure the internal resistance of a fresh or non-defective battery, and then decide the battery-deterioration evaluation values. Deteriorated batteries will have about 1.5 to 2 times (values for reference purposes) as high internal resistance, generating only
0.9 times as high voltage as a fresh one. Use these values as guidelines when determining deterioration evaluation values.

4.3 Setting Threshold Values for the Comparator

This section describes how tot set threshold values for the comparator (resistance warning threshold, resistance rejection value, voltage warning threshold).
You can set the threshold values through GENNECT ONE or GENNECT Cross. See GENNECT ONE (contained in the accompanying CD) or User Manual on GENNECT Cross.
Example: Threshold values for a battery that initially has
an internal resistance of 0.4 a voltage of 2 V.
Resistance warning threshold: 0.6 Ω (1.5 times the initial value) Resistance rejection value: 0.8 Ω (2 times the initial value) Voltage warning threshold: 1.8 V *: The initial values mean the resistance value a fresh battery or
non-defective battery has and the initial voltage value such a battery can generate.

Examples of how to read the comparator output table
Example 1:
If the measured resistance is less than or equal to the resistance warning threshold, and the measured voltage is more than or equal to the voltage warning threshold, the [PASS] segment will appear.
Example 2:
If the measured resistance exceeds the resistance warning threshold but is less than or equal to the resistance rejection value, and the measured voltage exceeds the voltage warning threshold, the instrument will show the [WARNING] segment and produce beeps.
When the resistance warning threshold and resistance are set to the same value, the boundary conditions are as shown below:
