Safety Precautions
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
z
Wear rubber gloves.
z
Eye protection should be worn to prevent injury from
accidental electrical arcs.
z
Only use tools (e.g. wrench) with insulated handles.
z
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.
z
Do not decompose, modify or damage the battery.
Otherwise, battery short circuit, leakage or even human
injury may be caused.
z
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.
z
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
