the i-u-chArGiNG coNcept
charges the lead-battery with constant
current of 800 mA (0,8A) until the end of charge voltage is reached for the
respective battery. The charger recognises this and switches to constant
current in order to adjust the charging current down (Maintenance charger).
The battery charger is therefore maintained at an ideal level. As a result, the
battery can be plugged into the charger for a longer period of time. This is
the reason why this device is suitable for “over wintering”. The plug charger is
protected against overcharge and short-term short-circuit (<1min.). A protective
circuit avoids charging in case of incorrect poling that could destroy the
battery as well as the charger. Incorrect poling will be indicated by a red
light.
