Battery Safety
Danger
All the battery maintenance and servicing procedures involving
internal access need special tools or keys and should be carried out
only by trained personnel.
WHEN CONNECTED TOGETHER, THE BATTERY TERMINAL
VOLTAGE WILL EXCEED 400Vdc AND IS POTENTIALLY
LEATHAL.
Battery manufacturers supply details of the necessary precautions to
be observed when working on, or in the vicinity of, a large bank of
battery cells. These precautions should be followed implicitly at all
times. Particular attention should be paid to the recommendations
concerning local environmental conditions and the provision of
protective clothing, first aid and fire-fighting facilities.
Ambient temperature is a major factor in determining the battery
capacity and life. The nominal operating temperature of battery is
20°C. Operating above this temperature will reduce the battery life.
Periodically change the battery according to the battery user manuals
to ensure the back-up time of UPS.
Replace the batteries only with the same type and the same number,
or it may cause explosion or poor performance.
When connecting the battery, follow the precautions for high-voltage
operation before accepting and using the battery, check the
appearance the battery. If the package is damaged, or the battery
terminal is dirty, corroded or rusted or the shell is broken, deformed
or has leakage, replace it with new product. Otherwise, battery
capacity reduction, electric leakage or fire may be caused.
Before operating the battery, remove the finger ring, watch,
necklace, bracelet and any other metal jewelry
Wear rubber gloves.
Eye protection should be worn to prevent injury from accidental
electrical arcs.
Only use tools (e.g. wrench) with insulated handles.
The batteries are very heavy. Please handle and lift the battery
with proper method to prevent any human injury or damage to
the battery terminal.
Do not decompose, modify or damage the battery. Otherwise,
battery short circuit, leakage or even human injury may be
caused.
The battery contains sulfuric acid. In normal operation, all the
sulfuric acid is attached to the separation board and plate in the
battery. However, when the battery case is broken, the acid will
leak from the battery. Therefore, be sure to wear a pair of
protective glasses, rubber gloves and skirt when operating the
battery. Otherwise, you may become blind if acid enters your
eyes and your skin may be damaged by the acid.
At the end of battery life, the battery may have internal short
circuit, drain of electrolytic and erosion of positive/negative
plates. If this condition continues, the battery may have
temperature out of control, swell or leak. Be sure to replace the
battery before these phenomena happen.
If a battery leaks electrolyte, or is otherwise physically damaged,
it must be replaced, stored in a container resistant to sulfuric acid
and disposed of in accordance with local regulations.
If electrolyte comes into contact with the skin, the affected area
should be washed immediately with water.
