48V 300A Battery Charge Discharge Tester To Test Battery Capacity
For Critical Power Maintenance
JET-DC500 48/30 Battery Charge Discharge Tester
1, Intelligent three steps charge function.
a. JET-DC500 performs charging in strict accordance with the curve
of charging characteristic automatically, flowing three steps of
charge mode: constant current charging→ (stabilized voltage at
uniform charging) current-reducing constant-voltage constant
charging → (automatically judge and turns to) → trickle floating
charging. It possesses the advantage such as quick charge speed,
high charge recovery efficiency and don’t need person on watch, no
overcharge danger for a long time, ensure service life of storage
battery and etc.
b. JET-DC500 will performs charging and displaying the information
such as charging current, charging volume, whole pack voltage,
individual cell voltage, charging time automatically. Parameters
can be setup, such as uniform charging voltage, floating charging
voltage, cell voltage peak limit, charging current, charging time,
c. It can adjust charging parameters during charging.
d. Works can be stopped by setup parameters, or stopped
2, Intelligent constant current/power discharge function.
a. JET-DC500 has two modes of discharge: constant current discharge
and constant power discharge. The user can choose the right mode to
fit your needs.
b. JET-DC500 performs discharging and displaying battery states
automatically. The parameters can be setup, such as pack charging
voltage, discharging volume, cell numbers, discharging time and
c. JET-DC500 can adjust the parameters during discharging.
d. When the discharging time, discharging volume, cell voltage
touched setup parameters, works can be stopped automatically or
3, Online monitoring function.
a. It is a real-time monitor, displaying battery data such as pack
voltage, cell voltage and monitor time.
b. User can stop the online monitor through setting the monitor
stop time or man-made stop. Battery states can be got through
setting pack and cell voltage alarm limit.
1, Large 8-inch touch screen with backlight, real-time display all
testing data: charging current, charging voltage, charging time,
charging capacity and inner temperature etc.
2, Multi self-protections can ensure safety, over voltage, over
current, short circuit, over temperature, etc.
3, Parameters can be setup flexibly and conveniently.
4. Works can be stopped automatically and artificially.
5. No red heat during works, even the cooling fan is stopped.
6. Parameters can be adjusted during the testing.
7. 100 data can be saved, viewed, deleted, exported.
8. It has power-off memory.
9. Powerful software supports data/curve management, analysis,
report statistic, generate test reports in excel/word/pdf, and etc.
Before choose a battery tester, we should know something:
Batteries are electrochemical devices. From the moment they are put
into service, batteries begin to deteriorate due to use and
environmental conditions. Therefore, the best way to maintain high
performance is through a comprehensive preventive maintenance
program, which includes regular checks and proper operation.
Through planned maintenance work, not only can catastrophic
accidents, economic losses, and personal injuries be avoided; it
can also ensure that the backup power supply is always in a normal
state, especially in the case of an emergency.
The overall performance of a string battery depends on the worst
performing cell. If one cell fails, the entire backup power system
will be at risk. Therefore, it is very important to accurately
collect the voltage of each cell in the battery pack.
The battery capacity tester can test real voltage and performance
of each cell battery.
Please remember that the life of a battery depends a lot on the
care we give it.
JET-DC500 48/30 Battery Charge Discharge Tester is a multi-function
device with functions of charging, discharging and online
monitoring. It is 3 in 1 machine. It can regenerate any disabled
cell battery of 2V/6V/12V, increase cell capacity and prolong
battery life, reduce the company’s cost and labor strength of
maintain personnel, also provide a total scientific testing way for
battery and power supply maintenance.
