Pay attention to all safety instructions regarding batteries indicated in this
manual.
The life span of the batteries greatly depends on the ambient
temperature and other factors such as the number of charges and discharges,
as well as their depth. The life span is between 3 and 5 years if the ambient
temperature is between 10 and 20ºC. different types of battery with different
service lives are available on request.
The KESSUPS 92RT series requires minimum maintenance. The batteries used in
the standard models are lead acid, sealed, valve regulated and maintenance
free. The only requirement is to charge the batteries regularly to extend their life
expectancy. while the UPS is connected to the mains supply, whether or not
it is running, it will keep the batteries charged and also offer protection from
overcharging and deep discharge.
