Why choose it

The M15 combines high charging current with a fully automatic multi-step process that protects battery health. Dedicated modes for reconditioning deeply discharged lead-acid batteries and for charging LiFePO4 batteries make it versatile. The IP44 rating allows use in dusty or damp environments, and the spark-free design ensures safe connection even in confined spaces.

Ideal use cases

• Charging and maintaining large lead-acid batteries in cars, motorhomes, boats, and agricultural machinery
• Charging LiFePO4 lithium batteries in modern vehicles and off-grid systems
• Reconditioning sulphated lead-acid batteries to extend their service life
• Using as a stable 12V power supply for diagnostics or equipment testing

Good to know

The charger operates from a standard 220–240V mains supply and includes temperature compensation to adjust charging voltage based on ambient conditions. Cables are 1.5m (AC) and 2.0m (DC) for flexible placement.
