• 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 life.
The nominal operating temperature of battery is 20℃. 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
of the batteries. If the package is damaged, or the battery terminal is
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.
• Don’t 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 closed inside 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.
