& Note
1 Charging time in table four means charging period after voltage reach the specified value,
initial max. current is less than 0.03C.
2 Follow above charging specifications, otherwise batteries will be overcharged or
undercharged, service life of batteries will shorten.
3 Charge the batteries as per cyclic charging parameters after capacity test discharge.

Cautions
Measure the output voltage of equipment once every 2 hours for new installations for the
Measure the output voltage of equipment once every 2 hours for new installations for the
initial 72 hours, to make sure the stable output of charging voltage. The output voltage
should also be confirmed during yearly maintenance check preventing the deviations due to
aging.

may occurred.
For cycle charging, timer is recommended to switchover to trickle charging mode,
preventing over-charging.
For temperature other than 25
charge voltage setting need to be compensated as
