CTEK MXTS 40 EU 12V/24V 40A/20A Automatic Battery Charger 56-995

Professional workshops and vehicle fleets often struggle with battery chargers that lack the power and flexibility to handle both 12V and 24V systems, especially when batteries are deeply discharged or need a stable power supply during diagnostics. The CTEK MXTS 40 EU solves this by delivering 40A at 12V and 20A at 24V in a fully automatic 8-step charger, compatible with all lead-acid battery types.

Who is it for

This charger is built for professional use in workshops, garages, and fleet maintenance where high charging currents and dual-voltage capability are essential. It is suitable for batteries from 20Ah to 1200Ah at 12V, and 10Ah to 600Ah at 24V, covering everything from cars to trucks and buses.

Main features

• Dual voltage: 12V and 24V automatic detection and charging
• High current output: 40A at 12V, 20A at 24V
• 8-step fully automatic charging process for optimal battery care
• Compatible with WET, MF, Ca/Ca, AGM, and GEL lead-acid batteries
• Recondition mode to revive deeply discharged batteries
• Supply mode for stable power during diagnostics or flashing
• Temperature compensation for safe charging in varying climates
• Desulphation feature to extend battery life
• Fan cooled for reliable continuous operation
• Low ripple (<4%) and back current drain (<1 Ah/month)

Specifications

• Input voltage: 220-240 VAC, 50-60 Hz
• Charging voltage: 12V / 24V
• Max charging current: 40A (12V), 20A (24V)
• Battery capacity: 20-1200Ah (12V), 10-600Ah (24V)
• Operating temperature: -20°C to +50°C
