If the MultiCharger 1500 rated current is exceeded during use, the unit internally measures how
long this situation lasts. After a maximum of one minute the current limit is reset to the rated value.
To avoid the MultiCharger 1500 overheating the unit allows a period for the charger recover five
times as long as the length of time for which the rated current was exceeded. For example, if the
rated current is exceeded for 30 seconds, the MultiCharger 1500 current limit is held at the level of
the rated current for 2 minutes 30 seconds. After that time, the rated current can again be
exceeded.
