Preface
Common rechargeable batteries include lithium batteries, nickel-cadmium batteries, nickel-metal
hydride batteries, and sealed lead-acid batteries. Among them, the lithium battery has the
characteristics of large capacity, light weight and high cycle times. It is widely used in mobile
phones, PDAs, digital cameras, camcorders, notebook computers and other fields. It is currently
the most advanced rechargeable battery. The lithium battery referred to here is a finished
product. The lithium battery pack is composed of lithium batteries (lithium ion batteries or inner
polymer batteries) plus a lithium battery protection board. Nickel-cadmium batteries are
rechargeable batteries that have been used earlier. They have the characteristics of low cost, low
internal resistance, and large current discharge. So far, they have been widely used in some
electric tools and electric vehicles.
Ni-MH batteries are similar to Ni-Cd batteries, but because they do not contain heavy metals,
they have less pollution to the environment. Currently, they are widely used in some common
consumer electronic products and have basically replaced the previous applications of Ni-Cd
batteries. Small sealed lead-acid batteries, also known as maintenance-free lead-acid batteries,
are currently mature in technology and are currently mainly used in fixed backup power
applications, such as uninterruptible power supplies, emergency lighting, and so on.
In response to the production and testing needs of these rechargeable batteries, a special
comprehensive tester for rechargeable batteries has been specially developed. This tester can
make a quantitative and accurate measurement of some basic parameters of the battery, and can
measure the open circuit voltage, internal resistance, and Charging, discharging performance,
and battery capacity are especially for lithium batteries. There are also overcharge protection,
overdischarge protection, overcurrent protection, short circuit protection and other functions,
and the corresponding values   have been measured, which greatly facilitates the production
and sale of batteries. Before and after-sales service work, you can intuitively judge the
performance and quality of the battery in a few simple steps, and it also has a quick screening

function. You can set the upper and lower limits of the measurement parameters, and you can
easily obtain a batch of finished battery products. Fast detection of defective batteries in the
medium and high production efficiency. In addition, some special functions are added to make it
have the characteristics of some general-purpose instruments and equipment, expand the
flexibility of the equipment, and have the characteristics of a wide range of applications.
In addition, the tester can provide software upgrade services according to customer needs. On
the basis of the basic model, it can be upgraded to a computer-connectable model through
software. The test data can be set and saved through the computer, and the test results can be
automatically recorded. The battery bar code is used to record the test data of each battery,
which is conducive to the analysis and control of production quality, product traceability, etc. In
addition, the test accuracy of voltage and internal resistance can be increased by an order of
magnitude by installing a hardware upgrade module to meet more Strict quality requirements.
The power battery performance comprehensive tester can test various types of lithium-ion
batteries, nickel-metal hydride batteries, polymer batteries (groups) within 60V100A, such as:
electric vehicles, power tool batteries, etc.; this testing equipment is widely used for electric
vehicles, electric Tool manufacturers of various types of batteries; it can meet the production
testing of high, medium and low-grade batteries by various manufacturers. It takes no more than
2 seconds to test a battery; it is fast, fully functional, and highly accurate; it is the most accurate
type of instrument currently on the market.
It is widely applicable to battery manufacturers of walkie-talkie batteries, mobile phone batteries,
digital batteries, etc.; it can meet the production testing of high, medium and low-grade batteries
by various manufacturers. The fastest test time for a battery is no more than 1 second; it is fast,
full-featured, and high-precision; it is the most accurate test instrument on the market. For the

Four. Function Page
After the boot screen is displayed, enter the main function menu display interface to display
voltage and battery internal resistance information,
In the system setting interface, press the "DISP" key to return to the previous test interface.
Internal resistance test interface
The internal resistance test interface can test the overcurrent value of the battery according to
the set conditions, as well as the battery's voltage before overcurrent, internal resistance, short
circuit protection time, NTC resistance R1 and R2.
The overcurrent test is aimed at the battery with a protection board. The battery protection
board will start the protection, disconnect the load function, and record the overcurrent current
value.
Overcurrent test parameter setting:
1. Initial current: The current will be used as the starting point during the over-current value test
to detect the over-current value;
2. Step time: The unit is ms, and the overcurrent value will increase the current at this time
interval until it reaches the overcurrent value of the protection board;
3. Step current: the step current of each step time, if you set 0.1A, the step time is 1ms, then step
0.1A every 1ms until the overcurrent value of the protection board is reached;
4. Threshold voltage: If the user sets the threshold voltage, the test can only be started when the
device detects that the battery voltage is greater than the threshold voltage.
Test Results

1. Overcurrent: the overcurrent protection value of the battery,
2. Protection: short circuit protection time of the battery,
3.---------V: The voltage value of the battery before the overcurrent test,
4.---------mΩ: the internal resistance of the battery.
After the over-current test parameters are set, the battery will be connected and the test will
start automatically after the internal resistance is stable.

Meaning of each parameter:
Load mode: This parameter has CC mode and CV mode optional. In CC mode, the
battery is discharged in constant current mode, and the load current parameter is valid; in
CV mode, the battery is discharged in constant voltage mode, and the load voltage
parameter effective.
Load voltage: After this parameter is set, when the load mode is CV mode, the
instrument will discharge the battery at a constant voltage with the value set by this
parameter.
Load current: After this parameter is set, when the load mode is CC mode, the
instrument will discharge the battery with constant current at the value set by this
parameter.
Cut-off voltage: After this parameter is set, the instrument will use this parameter to
interrupt the battery discharge operation.
After setting all parameters, connect the battery to be tested, press the function key
corresponding to the OFF switch at the bottom right corner of the screen, and the switch
will turn from OFF to ON to start the battery discharge operation; if you want to interrupt
the discharge operation in the middle, press again Press this function key and the switch
will turn from ON to OFF, which can interrupt the discharging operation of the battery. The
discharge capacity will be recorded in real time during the test
CV mode selection: When the overcurrent value is greater than 2.5 times the actual
working current value or the overcurrent value is greater than 10A, select this mode.
The test speed in this mode is fast, but some batteries may not support this mode.
If the test overcurrent value in this mode is 0, it is recommended to use the CC
mode.
CC mode selection: Otherwise, select this mode.

current at the value set by this parameter.
Limit current: After this parameter is set, the instrument will charge the battery with constant
current at the value set by this parameter.
Cut-off current: After this parameter is set, the instrument will use this parameter to interrupt
the battery charging operation.
After setting all parameters, connect the battery under test and press the function key
corresponding to the OFF switch at the bottom right corner of the screen. The switch turns from
OFF to ON to start the battery charging operation; if you want to interrupt the charging operation
