CTEK Multi XS 25000 Battery Charger
The Ctek MULTI XS 25000 is a powerful unit for batteries that require rapid charging: in boats, vehicles and workshops. With built-in functions that constantly analyse the state of the battery.
The MULTI XS 25000 is delivered with a battery lead with clamps, colour coded for easy +/- identification.
The charger also has a sensor cable located together with the battery leads. The unit automatically adjusts the charge voltage if the temperature deviates from +25°C. Higher temperatures lower the voltage and lower temperatures raise the voltage. The sensor cable can be extended or shortened without affecting functionality.
FEATURES & BENEFITS:
- Eight step, fully automatic switch mode model.
- Revives, charges, checks and maintains virtually all types of 12V lead-acid batteries (Wet, MF, GEL and AGM) from 50Ah to 500Ah.
- Desulphation mode with pulses.
- Soft start for severely discharged batteries.
- Recondition mode with controlled top charging recovers the capacity of a severely discharged battery.
- Maintenance pulse charging increases battery life and gives superb performance.
- Supply mode for use as a power pack, battery backup (UPS) or float maintenance
- Charges even drained batteries.
- Temperature compensated for optimal charging voltage at all times.
- Low back current drain, low ripple and input voltage independent (170-260V).
- High efficiency: 85%
- The charger can be connected for months, ideal for seasonal vehicles.
- Compact design with mounting holes for permanent assembly.
- 2 year warranty.
SAFETY FEATURES
- Electronic safe, the charger will not damage vehicle electronics. The battery does not normally need to be disconnected from the vehicle when charging.
- Minimal gas build-up and a patent-pending spark protection system. (however, in supply mode the spark free feature is disconnected).
- Short circuit and reverse polarity protected.
- Double insulation.
- Cooling with power controlled fan.
- Approved for outdoor use, (IP44).
- Progressive temperature protection.

*) Back current drain is what drains the battery if the charger is connected without the power cord connected.
**) Ripple denotes the amount of interference there is to the current and voltage. A high current ripple heats the battery and shortens its life. A linear charger has a current ripple of 70 - 400% which is much larger than the maximum 5% for a modern sealed battery. Voltage ripple could harm other equipment, which is connected to the battery.
The MULTI XS 25000 delivers voltage and current with very low ripple. The battery gains a long service life and there is no risk of damage to other electronic devices connected to the battery.
***) IP 44 cannot be guaranteed unless the charger is positioned with its top or long side facing up.
