6 Routine Maintenance
6.1 Application and maintenance of storage batteries
Battery safety description:
The battery life will be shortened along with the rise of ambient temperature. Battery shall be
periodically replaced to guarantee the normal operation of UPS, and enough backup time shall
be guaranteed.
If UPS is not used for a long time, the battery shall be charged once every 4 to 6 months. In high
temperature zone, the battery shall be charged and discharged every two months, and the
charging time for each time shall not be less than 12h.
The maintenance of storage batteries can only be conducted by the professionals in the field of
storage battery.
The storage batteries may suffer from the danger of electric shock and short circuit. To avoid
personal injury caused by electric shock, please pay attention to the following precautions
during the battery replacement.
Do not wear wristwatches, rings, and other metal objects;
Use insulating tools;
Wear rubber shoes and gloves;
Do not place metal tools or metal components on the batteries;
Before dismantling the battery terminals, disconnect the loads connected on the batteries
first.
Do not use fire to dispose the batteries or battery packs. Otherwise, it will cause explosive
damage.
The storage batteries shall not be disassembled or damaged by nonprofessionals, because the
electrolyte inside the batteries contains strong acid that may cause damage to skins and eyes. If
coming into contact with the electrolyte by accident, use plenty of clean water to wash
immediately, and then go to the hospital for examination.
Please do not short-circuit the battery cathodes and anodes. Otherwise, it will cause electric
shock or fires.
Please do not touch the battery terminals. If the battery circuit is not isolated from the input
voltage circuit, the hazardous high voltage might generate between battery terminals and
ground.
Battery Maintenance of the UPS with Long Time Delay (conduct good maintenance to the
batteries, so as to prevent the precision equipment from being damaged during the power
failure, which is of great importance):
