Fully electronic high-frequency battery chargers - the latest generation with pulse charge maintenance. Suitable for conventional open batteries but also for maintenance-free batteries, gel batteries, AGM and lead-calcium batteries. The high-frequency chargers work according to the IU-directives. Electronics completely protected without voltage peaks, so batteries can remain connected to vehicle power during charging.
After a soft start with low initial current the chargers load the batteries completely. Afterwards they switch automatically to the pulse charge maintenance. The batteries can also be connected long term with the charger. The battery receives a repeated pulsating charge which eliminates a sulfating of the battery. Partly sulfated batteries can regain their complete charging capacity.
