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rst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predened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nished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.
