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 lethal.
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 charge 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
