6. 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.

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.
