Battery Charger RLD
User's Manual
MAINTENANCE
The MAINTENANCE function is useful to keep the battery in perfect condition when it's not used
for an indefined time (weeks, months, ...).
It is sufficient to leave the battery connected to the charger: the control board will keep the
battery voltage under control and will activate the charger automatically when the voltage falls
below a predefined minimum theshold.
While the charger is off and the battery voltage is being monitored, this message is displayed:
If the voltage falls below the minimum threshold, the charger will give a refresh charge to pull up
the voltage to a programmed maximum threshold, and the display will show the message: “F2”.

NOTES
With this “voltage controlled” maintenance/refresh system, the battery will be kept in perfect
condition for an undefined time, without any risk of undercharge or overcharge.
If the battery is in ideal condition (no self-discharge) the refresh charge will never be activated.
If the battery is in bad condition (self-discharge is significant), the refresh charge will be often
activated and the battery will be kept charged without problems.
