needs and required functionality. The following recommendations should only be
regarded as guidelines. Please observe the battery manufacturer recommendations
in the event of uncertainty.
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. After about
two seconds the charger activates the selected mode. The selected mode setting will
be restored next time the charger is connected.
The table explains the different modes:

Explanation
1.2–14
Mode 14.4V/0.8A
This mode shall be used for batteries smaller than 14Ah.
14–140
Mode 14.4V/4A
Normal mode for wet batteries, MF and for most GEL
batteries.
14–140
Mode 14.7V/4A
This mode is recommended for charging batteries at
temperatures lower than +5°C. It is also recommended for
many AGM batteries. This setting is not recommended for
maintenance charging when the temperature temporarily
exceeds +5°C. Here we recommend the 14.4V/4A or
14.4V/0.8A mode.
RECOND 14–140
This mode is used to recover deeply discharged batteries

in the bottom, low on top). This problem arises primarily in
open vented batteries, i.e. not Gel and AGM. Use this step
with care, because the high voltage may cause some water
loss in the battery. Contact the battery supplier if you are
uncertain. 15.8V is normally no problem for electronics in
12V systems but consult your supplier when in doubt. The
service life of lamps drops at higher voltages. Maximum
effect and minimum risk for electronics is achieved by
charging a disconnected battery in this step.
