1.
The
tester
outputs
voltage
of
4.4V
in
open-circuit
mode.
Upon
detecting
the
recharge
current, it starts the test.
2. Test battery voltage and check whether it is in the range set.
3. Test battery impedance and check whether it is in the range set.
4. Test R1 and check whether it is in the range set. (This function is optional.)
5. Test R2 and check whether it is in the range set. (This function is optional.)
6.
Test
communication
ID
and
check
whether
it
matches
the
model
set.
(This
function
is
optional.)
7.
Test
discharge:
Discharge
the
battery
with
the
specified
current
(usually
0.5C
of
the
battery
capacity set). If the voltage drop is within the range set, the discharge is qualified. (This
function is optional.)
8.
Test
over-current
protection:
Gradually
increase
the
load
current
of
the
battery
to
check
whether the battery cuts off current for protection, and record the maximum current before
the protection and check whether it is within the range set. (This function is optional.)
9.
Test
charge:
Charge
the
battery
with
the
maximum
charge
current
set.
If
the
charge
current
is higher than 0.5C of the capacity set, the charge is qualified. (This function is optional.)
10.
Test
short-circuit
protection:
Use
a
high-current
MOSFET
or
relay
to
directly
short-circuit
the two ends of the battery, and check whether the battery is disconnected within the
specified short-circuit protection period. If it is disconnected successfully and the voltage is
automatically restored (through charge or open-circuit), it is indicates that the battery is
qualified. (This function is optional.)
During the above test process, if any test item fails, the tester will beep for a long time,
prompts that the corresponding function fails, and stops the subsequent test items. If all the
test items succeed, the tester will beep twice, displays all the test results, and prompts that
the test succeeds. See the figure below.

VOL and V-L are displayed alternatively; VOL indicates the open-circuit voltage of the battery,
and V-L indicates the load voltage of the battery.
VOL= 7.98V R1= 0.0K
IMP= 198mΩ R2= 0.0K
OVC= 0.00A
