3. Charging the battery
{
The battery charger of the UPS automatically charges the battery whenever the power
cord of UPS is connected to a acceptable utility power.
{
When UPS is running for the first time, charge the UPS for at least 6 hours to ensure
batteries inside are fully charged before operation.
{
You may immediately use the UPS without having to wait for the batteries to be fully
charged. However, it is advisable not to do this as UPS will have a shorter back-up time
than expected if such action is taken.
