CTEK MXT 4.0 is a switch mode battery charger, specially adapted for 24V batteries. The CTEK MXT 4.0 is a cost effective and reliable charger adapted for use with items like wheelchairs, snowmobiles and piste machinery, back-up systems, school buses and other 24V vehicles.

Features & Benefits

  • Eight step, fully automatic switch mode model.
  • Revives, charges, checks and maintains virtually all types of 24V lead-acid batteries (Wet, MF, Ca/Ca, GEL and AGM) from 8Ah to 100Ah, up to 250Ah maintenance.
  • 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.
  • Charges even drained batteries.
  • Temperature compensated for optimal charging voltage at all times.
  • Low back current drain, low ripple and input voltage independent (220-240V).

*) 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 MXS 4.0 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.
