Power for heavy-duty vehicles with 24V batteries

The MXT 14 has the same characteristics as the MXS 25, but is adapted for 24V batteries, which makes it perfect for buses, trucks, larger boats or the workshops that service these vehicles. The SUPPLY mode means the battery charger provides power even without a battery. The SUPPLY mode is indispensable when changing the battery as you avoid losing irreplaceable program settings. Using RECOND mode, you can correct the acid stratification that often occurs in deeply discharged batteries. The battery thereby has its power restored and has a longer service life.

Features & Benefits

  • Eight step, fully automatic switch mode model.
  • Revives, charges, checks and maintains virtually all types of 24V lead-acid batteries (Wet, MF, GEL and AGM) from 28Ah to 300Ah, up to 500Ah 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.
  • 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.

*) 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.
