CTEK MXS 10

Fully electronic high-frequency battery chargers with pulse charge maintenance of the latest generation. Suitable for conventional open batteries, but also for maintenance-free batteries, GEL batteries, AGM and lead-calcium batteries. The high-frequency chargers operate according to the IU characteristic. Completely electronically safe, without voltage peaks. This means that batteries do not need to be disconnected from the on-board power supply during charging.
After a soft start with low initial current, the devices fully charge the batteries. They then switch automatically to pulse charge maintenance. The batteries can also remain connected to the charger for a long time. Thereby, the battery receives a pulsed charge again and again, which counteracts sulphation. Thus, partially sulphated batteries can regain their full charging capacity.
Additionally with MXS 10, PRO 25S, MXT 14:  
With "SUPPLY" function: Special switchable mode in which the unit is used as a power source for a vehicle while the battery is removed (radio code etc.).
