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 <14Ah.
Mode 14.4V/3.3A
Normal setting for wet batteries, maintenance free and for most Gel batter-
ies. 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 <41°F. It is also
recommended for many AGM batteries like Optima, Maxxima and Odysses.
Consult your battery manufacturer when in doubt.
CHARGING CYCLE
The WeatherTech ® BatteryCharger 200 operates in a four step fully automatic cycle. It
starts the charging with an almost constant current (0.8A or 3.3A) until maximum volt-
age (14.4V or 14.7V) is reached. At this point the charger switches to constant voltage,
and the current supply to the battery is gradually reduced. If the current drops to 0.4A,
the charger switches to pulse maintenance. If the battery is charged and the terminal
voltage of the battery falls to 12.9V, the charger automatically starts again at the first
step of the charge characteristic. The BattteryCharger 200 measures both voltage and
current in order to determine out whether the charging process is finished or whether a
new charging cycle must be started. Various methods are used, depending on the time
of the measurement; see table:
