Maintenance
UPS use in the appropriate environment (see 3.2 installation
considerations) can be free maintenance or less maintenance.
5.1 Battery maintenance
1. It is recommended that the batteries are manually charged or
discharged
Once every three or four months if the UPS has not been used for a
long time or the power is long-term uninterrupted. The battery will be
fully discharge to low-voltage protection shutdown. Then it needs to
be fully charged at once.
2. In high temperature area, batteries should be manually charged and
discharged once every two months. The process is the same as that
said above.
3. Under normal circumstances of using, the battery working life is three
to five years. If you find that the battery do not act well such as
obviously shortening of backup time, too much imbalance on battery
voltage and so on, the battery should be replaced as soon as possible,
which must be performed by qualified personnel.
4. When replace battery, it is recommended to change battery all together
instead of changing separately.
