5.2. Charging Batteries
The batteries are valve-regulated, non-spillable, lead acid batteries and should be kept charged to attain their
design life. The UPS charges the batteries continuously when it is connected to the utility input power.
If the UPS will be stored for a long time, we recommend connecting the UPS to input power for at least 24 hours
every 4 to 6 months to ensure full recharge of the batteries.
