8. Battery Maintenance, Replacement and
Disposal
8.1 Maintenance
■
Battery replacement should be performed by qualified personnel.
This series of UPS only requires minimal maintenance. The
batteries used for standard models are regulated sealed
lead-acid maintenance free. 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
connected to the utility power, whether the UPS is turned on or
not, the UPS keeps charging the batteries and also offers
overcharging and over-discharging protection.
The UPS should be charged once every 4 to 6 months if it has
not been used within this time frame.
In 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 is 3 to 5 years.
Unusual or extreme operation may cause a shortening of
battery life. If batteries are discovered to have reached the end
of their usable lives replacement should be made as soon as
possible.
Replace batteries with the same number and same type of
batteries.
Do not replace the batteries individually. All the batteries should
be replaced at the same time following the instructions of the
battery supplier.
If the battery service life (3~5 years at 25°C ambient
temperature) has been exceeded, the batteries must be
replaced.
