Analysis
Tests the self-discharge. If the self discharge is too high, the charging is interrupted
and error mode indicated.
Recond
Reconditioning of deeply discharged batteries. This step is used to restore deeply
discharged open vented batteries. With increased charging voltage over a limited
time, the voltage is allowed to rise so that the battery starts to emit gas. As a result
you get a mix in the battery that is good both for its capacity and service life. Note
that the battery may emit explosive gases during this step. Recond takes place
between the analysis and maintenance steps. When choosing the Recond-mode,
the charger will first charge your battery up to full-charged. When this is done
the charger will start the Recond and the upper Recond-lamp will lit. The charger
reconditions the battery between 30 min and 4 hours depending on the need of the
battery. Once the recond is done, the charger will switch into maintenance-mode
(green light for fully charged). The bottom Recond-lamp will still be on as a reminder
that you have chosen the Recond.
Maintenance charge – Float
Charging with constant voltage.
Maintenance charge – Pulse
The state of charge varies between 95% and 100%. The battery receives a pulse
when the voltage has dropped to a predefined level. This keeps the battery in trim
when not in use. The charger could be connected for months at a time. Check the
water level in the battery if possible. The charger measures the terminal voltage
continuously to determine whether a charge pulse should be started. If the battery is
loaded and/or the terminal voltage drops, the charger starts a charge pulse so that
the terminal voltage rises to the set level. The charge pulse is then finished and the
cycle is restarted. If the terminal voltage drops even lower, the charger automatically
reverts to the beginning of the charge cycle.

TEMPERATURE PROTECTION
The chargers are protected against overheating. The power reduces when the
ambient temperature increases.
The charger may be perceived as being hot during charging. This is completely
normal, although you should avoid placing it on a sensitive surface.
