8. Battery Maintenance, Replacement and
Disposal
8.1 Maintenance
■
This series UPS only requires minimal maintenance. The battery
used for standard models are value regulated sealed lead-acid
maintenance free battery. These models require minimal repairs.
The only requirement is to charge the UPS regularly in order to
maximize the expected life of the battery. When being connected
to the utility power, whether the UPS is turned on or not, the UPS
keeps charging the batteries and also offers the protective
function of overcharging and over-discharging.
■
The UPS should be charged once every 4 to 6 months if it has not
been used for a long time.
■
In the regions of hot climates, the battery should be charged and
discharged every 2 months. The standard charging time should
be at least 12 hours.
■
Under normal conditions, the battery life lasts 3 to 5 years. In
case if the battery is found not in good condition, earlier
replacement should be made. Battery replacement should be
performed by qualified personnel.
■
Replace batteries with the same number and same type of
batteries.
■
Do not replace the battery individually. All the batteries should be
replaced at the same time following the instructions of the battery
supplier.
■
Normally, the batteries should be charged and discharged once
every 4 to 6 months. Charging should begin after the UPS shuts
down automatically in the course of discharging, the standard

8.2 Replacement and Disposal of Batteries
1)
Before disposing of batteries, remove conductive jewelry such as
necklace, wrist watches and rings.
2)
If it is necessary to replace any connection cables, please
purchase the original materials from the authorized distributors or
service centers, so as to avoid overheat or spark resulting in fire
due to insufficient capacity.
3)
Do not dispose of batteries or battery packs in a fire, they may
explode.
4)
Do not open or mutilate batteries, released electrolyte is highly
poisonous and harmful to the skin and eyes.
5)
Do not short the positive and negative of the battery electrode,
otherwise, it may result in electric shock or fire.
6)
Make sure that there is no voltage before touching the batteries.
The battery circuit is not isolated from the input potential circuit.
There may be hazardous voltage between the battery terminals
and the ground.
7)
Even though the input breaker is disconnected, the components
inside the UPS are still connected with the batteries, and there are
potential hazardous voltages. Therefore, before any maintenance
and repairs work is carried out, switch off the breaker of the
battery pack or disconnect the jumper wire of connecting between
the batteries.
8)
Batteries contain hazardous voltage and current. Battery
maintenance such as the battery replacement must be carried out
by qualified personnel who are knowledgeable about batteries. No
other persons should handle the batteries.
