REFRESH phase :
It is an automatic weekly cycle in order to prevent battery self‐discharging and possible sulphation and then to optimize
the battery life duration.
It will occur only after a complete recharge cycle (BOOST, ABSORPTION and FLOATING).
The charger will generate automatically a safe timed voltage step every 7 days.
Phase REBOOST :
It is also automatic and consists in coming back to a BOOST voltage if the DC utilizations require it (i.e. after a complete
recharge cycle BOOST, ABSORPTION and FLOATING if a some DC constant consumptions are detected the charger will
restart a new complete charge cycle including a BOOST phase).
This REBOOST phase will be authorized after a sense of the certain battery voltage during a determined duration.
BOOST in OFF position
With this setting, the YPOWER charger produces a single‐stage UI type load curve. It generates a constant voltage,
supplying the current required by the battery(ies). Recharging time depends on the state of the battery, being longer
than when the BOOST is in the ON position.

These indicators are visible from the front of the appliance through the light guides, thereby allowing operation of the
appliance to be monitored.
