, it set constant current for charging and discharging.
Charge the capacitor with standard current to rated voltage, after hold on for 30min, discharge
with the same current to 0.1V.
Self-discharge
Measuring method
—the capacitor should be fully discharged and short-circuited for 6 hours.
According to 10mA/F and C
R
, it set constant current for charging and discharging.
the capacitor is charged to the voltage U
R
with constant current I, the capacitor is continues to
charge for 30 min at the rated voltage U
R
;
—test the terminal voltage of capacitor after 24 h at open circuit under room temperature
Handling Precautions and Guidelines
For safety application, please contact chenglue directly for any technical specifications,
handling precautions and guidelines critical to application.
Precautions
Prohibition of disassembly
The disassembling may generate internal short circuit in the cell, which may cause gassing,
leakage, explosion, or other problems.
Electrolyte is harmful: In case the electrolyte comes into contact with the skin, or eyes,
physicians shall flush the electrolyte immediately with fresh water and medical advice is to be
sought.
Prohibition of dumping of cells into fire
These may cause explosion of the cells, which is very dangerous and isprohibited.
Prohibition of cells immersion into liquid
The cells shall never be soaked with liquids such as water, seawater, drinks such as juices,
coffee or others.
Prohibition of use of damaged cells
The cells might be damaged during shipping by shock. If any abnormal features of the cells are
found such as damages in the cell package, smelling of an electrolyte, an electrolyte leakage and
others, thecells shall never be used any more
The Cells with a smell of the electrolyte or a leakage shall be placed away from fire to avoid
firingor explosion.
Handling Guidelines
It is not suitable that cell is used under such conditions: AC circuit and wave filtering.
Work voltage of cell should not exceed Max. work voltage of cell during using. Otherwise, will
shorten shelf life, even cause swelling, leakage or crack.
Please check the polarity before using. If working under reverse polarity, cell will not only
shorten shelf life, but also heavy damage, such as swelling, electrolyte leakage etc.
Environment
Work temperature will have an influence on shelf life of cell. As usual, higher work temperature
will shorten shelf life. So, it is better that cell works under as possible as low environmental
temperature.
Work temperature of cell should consider internal work temperature in the unit and
temperaturerise when cell works.
IR dropIR
When main power sources shut down, cell will change into work mode from failure mode, at
the same time, OCV will decrease due to IR drop. So please choose proper product type according
to impedance specified in product datasheet and applied current.
Cells in series connection
When cells in series connection for higher work voltage, it should be assured that work voltage
of any single cell must not exceed Max. work voltage of single cell, otherwise, will shorten shelf
life, even cause swelling, leakage or crack.
