Preface
The frequently used rechargeable batteries fall into these types: Li-ion battery, Nickel-Cadmium
battery, Nickel-Metal hydride battery, sealed lead-acid battery, and so on.
Among them, the Li-ion battery features large capacity, light weight, high rechargability, so it is
widely used in fields such as mobile phone, PDA, digital camera, camcorder, and notebook
computer. It is the most advanced rechargeable battery. Here Li-ion battery refers to the finished
Li-ion battery pack, which consists of lithium battery core (Li-ion core or lithium polymer core)
and lithium battery protection panel.
Nickel-Cadmium battery has a longer history. It features low cost, low impedance, and
high-current discharge, so it is still widely used in electric tools and electric vehicles.
Nickel-Metal hydride battery is similar to Nickel-Cadmium battery, but it is more
environment-friendly because it contains no heavy metal. It is widely used in common customer
electronic products and has almost become a substitute for the Nickel-Cadmium battery.
Small sealed lead-acid battery is also known as maintenance-free lead-acid battery. Because of
mature technique, it is widely used for fixed standby power supply, such as UPS and emergency
lighting.
To check the status of these rechargeable batteries, we have launched a specialized integrated
battery tester. This tester can measure basic parameters of the rechargeable batteries accurately,
including open-circuit voltage, impedance, charge/discharge performance, and capacity. For
lithium battery, it also offers functions such as over-charge protection, over-discharge protection,
over-current protection, and short-circuit protection, and can measure the corresponding values.
This greatly facilitates the production and pre-sale/after-sale services of batteries. With this tester,
you can easily and visually identify the performance and conditions of the batteries. You can also
use the fast-screening function, namely, you can set upper and lower thresholds to quickly detect
the defective batteries among a batch of finished batteries, improving the production efficiency.
Besides, the tester offers some unique auxiliary functions, so that it has some features of a
common communication tool, thus improving the flexibility and enlarging the application scope of
the tester.
In addition, the software of this tester can be upgraded as required. The base version of the tester
can be upgraded to connect with a computer. After that, the computer can be used to set and save
test data, automatically keep the test records. The test data of each battery can be kept according to
its bar code, facilitating the analysis of and control over the production quality and problem

Function Overview
The basic functions of the battery tester include:
1.
Static Test
1)
Voltage test (For the Li-ion battery in protection status, this function can be
automatically woken up.)
2)
Impedance test
3)
Charge test
4)
Discharge test
5)
Over-current test (for Li-ion battery only)
6)
Short-circuit protection function test (for Li-ion battery only)
7)
Identification resistor 1 (or thermal resistor) test
8)
Identification resistor 2 (or thermal resistor) test
9)
Setting upper and lower thresholds for the above parameters whose values can be
measured, for the purpose of fast-screening.
10) Communication code test for the batteries with communication IDs (Currently, this
function is only available for DS2502.)
2.
Capacity Test
After this function is selected, the tester automatically selects the most appropriate voltage
and current according to the selected battery type, the number of cells connected in serial
and the battery capacity, and then conducts a complete charge & discharge test. During the
discharge process, the tester calculates the actual capacity of the battery, providing a solid
reference basis for judging the performance of the battery.
3.
Battery Charge
After this function is selected, the tester can be used as a multi-function smart recharger. It
can charge different combinations of batteries (BTS-2004HH can quickly charge up to 4
Li-ion cells connected in serial, 12 Nickel-Metal hydride cells connected in serial, and 6
maintenance-free cells connected in serial), greatly facilitating the use and test of the
batteries. It can real-time display the charge duration and the charged capacity (measured in
mAH).
4.
Battery Discharge
After this function is selected, the tester can discharge the battery. It can also control the
discharge cut-off voltage. This avoids the over-discharge which may be occurred during the
5

http://www.test-pad.com
discharge through electronic load or resistor. With this tester, the battery manufacturer can
test batteries easily. After selecting the battery type, voltage and capacity are selected, the
tester can start the smart discharge to discharge the battery safely.
5.
Program DC Power
After this function is selected, the tester can be used as a precise digitally-controlled DC
power supply unit. The maximum output voltage is 20V (BTS-2004H) or 10V
(BTS-2002H); the maximum output current is 2A. You can set the output voltage and
limited current directly. The tester can be easily used for special charge and test of battery
and power supply of other devices, thus enlarging the application scope of the tester.
6.
Program E-load
After this function is selected, the tester can be used as a precise digitally-controlled
electronic-loading unit. It can work in these modes: constant current, constant voltage,
constant resistance, and constant power. In the modes other than constant-voltage mode, the
cut-off voltage can be set to facilitate the measurement of battery discharge. When the load
voltage is lower than the cut-off voltage, the operating current can be cut off to avoid the
damage caused by deep discharge of the battery. Besides, this tester can be used in
occasions where electronic load is needed, for example, recharger test and aging test of
switching power supply.
7.
VOL and IMP
After this function is selected, the tester can be used as a general 3 1/2 digital voltmeter or a
digital milliohm meter. It can continuously indicate the input voltage and battery impedance,
and the resistance value of two identification resistors. It can be used in place of a special
impedance meter for fast screening and detection of batteries.
8.
Enter Calibration
After this function is selected, the tester can be calibrated without removing the outer shell,
thus to ensure high measurement accuracy. The following items can be calibrated: voltage
measurement, impedance measurement, charge current measurement, discharge current
measurement, and so on. Before the use of this function, it requires the user to input a
confirmation password to avoid unauthorized operation.
.
9.
Read ID (Currently, this function is available for DS2502 only and applicable to the
batteries used in MOTO mobile phones.)
After this function is selected, the tester can read all the internal data of DS2502. It
real-time displays the data of any address and the last CRC data. By comparing the CRC
data of the last two bytes, you can judge whether the transmitted data is correct.

Connection Method
There are seven connection terminals on the tester. P+ and P- are respectively connected to the
anode and cathode of the battery to serve as the connection channel of the charge current and
recharge current. R+ and R- are also respectively connected to the anode and cathode of the
battery and are converged at the battery electrode to serve as the connection channel of
measurement signals. In this way, the four-wire measurement system can remove the measurement
error caused by the wires and improve the measurement accuracy.
Besides, R1 and R2 respectively serve as the connection terminals of identification resistors or
thermal resistors. If they are needed, use wires to connect them to the corresponding terminals; the
ID wire is used to measure some batteries with IDs. Currently, this function is optional.
The following example shows the test of a Li-ion battery with identification resistors. The
connection is shown below.
Multi-function Rechargeable Battery Test Center
In the above figure, five wires are needed. P+ and R+ are respectively connected to the anode of
the battery, and P- and R- are respectively connected to the cathode of the battery. In this way, the
tester can measure the impedance accurately. If accurate impedance measurement is not needed,
you can also directly connect P+ and R+ in parallel and connect P- and R- in parallel, and then
respectively connect them to the anode and cathode of the battery. In this case, the measured
impedance might be relatively high, while no other effects will be exerted. If identification
resistors or thermal resistors need be tested, you can use separate wires to connect R1/R2 ports to
the corresponding terminals on the battery.
Caution: Because of the over-current protection and short-circuit protection functions of the
battery, relatively high current is required, so relatively larger wires are required, thus to avoid
inaccurate measurement due to the impedance of the wires.

If the ID of a MOTO mobile phone needs be tested separately, simply connect the terminal of the
ID to the ID terminal, and use a separate wire to connect the P- of the battery to the P- terminal of
the tester.
If the capacity of Nickel-Metal hydride battery or Nickel-Cadmium battery needs be tested or
these two types of batteries need be charged, our delivery-attached temperature sensor is required.
Place the temperature sensor close to the surface of the battery to be tested, and connect the
temperature sensor to the P- and R2 of the tester. Then the tester can monitor the temperature of
the battery, thus to better judge the condition of the battery and ensure safe charge.

The tester accumulates the charged capacity during the charge process and accumulates the
discharged capacity during the discharge process. When the discharge ends, the displayed
recharged capacity indicates the capacity of the battery working in the current mode.
Caution: By default, both charge current and discharge current of the battery are 1C of the battery
capacity set. If a low discharge current is needed, set a low battery capacity; if a high charge
current is needed, set a high battery capacity. In 1C mode, a complete capacity test may take 3~4
hours. If a relatively low battery capacity is set, the test will take a bit longer time.
During the test, you can press ENTER anytime to pause the test. After that, press ENTER again to
continue the test, or press ESC to abort the test and return to the setting mode.

Calibrating Instructions for Integrated Battery Tester BTS-2002
32
Shenzhen TestPad Electronic Co., Ltd.
http://www.test-pad.com
Warning: The tester shall be calibrated by the qualified electronic engineering technicians or the
electronic engineers with rich experience in instrument calibration, otherwise improper calibration
may severely degrade the measurement accuracy of the tester or result in the malfunction of the
tester.
To ensure accurate measurement, it is necessary to calibrate the tester after the initial assembly or
a long-time use of it.
The following parameters of the tester can be calibrated:
1. Battery measurement
It is related to the measurement accuracy of battery
voltage.
2. Charge current measurement
It is related to the setting accuracy of charge current.
3. Discharge current measurement
It is related to the measurement accuracy of discharge
current and battery capacity.
4. High-current grade measurement
It is related to the measurement accuracy of battery
over-current protection current.
5. Impedance measurement multiplying factor
It is related to the measurement accuracy of battery
impedance.
6. Impedance measurement offset
When this parameter is used for impedance test, it
corrects the impedance error of the correction line.
Required components and materials:
1.
A power source with an output current of higher than 3.5A is required for the calibration of
voltage and discharge current grade. For example, use a DC stabilized power source of higher
than 5V/4A. If such source is not available, use a fully charged Li-ion battery with a capacity
of higher than 2AH, for example, an ordinary 18650 columned Li-ion battery.
2. A discharge load is required for the calibration of discharge current. For example, use a DC
electronic load, and adjust it to the constant-current (1.5A) mode. If such load is not available,
use a high-power resistor of 3Ω/20W.
3. A high-precision resistor with a resistance of 100~200mΩ is required for the calibration of
impedance. Use a high-precision digital bridge to measure the impedance of the resistor (in
the 1KHz AC measurement mode).
4. A high-precision digital multimeter is required to be the reference instrument for the
calibration of current and voltage. It is recommended to use a Fluke 187 high-precision digital
multimeter or a digital multimeter with a higher precision. An ordinary digital multimeter,
though acceptable, will cause some deviation in the calibration.
