If the indicator for charge and maintenance charge are flashing alternately, this
may have the following causes:
•
Interruption of the charging process because a cable has become loose or because the
battery is not conducting.
•
The battery is sulphated. If the indicator flashes for more than 30 minutes the battery
may be defective and should be replaced.
•
If the flashing signal is flashing at intervals of more than 10 seconds, then there is a
high self discharge of the battery, indicating a bad battery.
BATTERY TYPES AND SETTINGS
MULTI US 3300 can easily be set for different types of batteries or conditions. The fol-
lowing recommendations should however only be seen as guidelines. Please consult the
battery manufacturer for further instructions.
Settings are made by pressing the ”MODE-button” and stepping forward one press at a
time until the required mode is reached, the button is then released. The selected mode is
saved in a memory in the charger and remains there even if the charger is switched off.
Mode 14.4V/0.8A
This mode is normally used for batteries <14 Ah.
Mode 14.4V/3.3A
Normal setting for wet batteries, maintenance free and for most Gel batteries. Some
gel batteries prefer a slightly lower voltage. Please consult the battery manufacturer
when in doubt.
Mode 14.7V/3.3A
This setting is recommended for a battery at temperatures < 5 degrees C. It is also
recommended for many AGM batteries like Optima, Maxxima and Odysses. Consult
your battery manufacturer when in doubt.
