UPS works properly, there is no need for battery maintenance. Batteries used for standard
models are value regulated sealed lead-acid maintenance free battery. These models require
minimal repairs. The only requirement is to regularly charge the UPS 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 on charging the batteries which are protected against overvoltages and
serious discharging.
When the UPS is not being used nor has been used for a long period of time, it is recommended to
charge the battery of the UPS once every 4 to 6 months.
In tropical regions, the battery should be charged and discharged every 2 months. The standard
charging time should be at least 12 hours.
Under normal conditions, at room temperature 20°C, battery life goes from 3 to 5 years. If the battery
is flat, it has to be replaced and replacement should be performed by qualified personnel.
Batteries have to be replaced 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.
Batteries should be discharged once every 3 months. To do so switch the UPS to battery mode for 8
hours.
