Key Benefits
Calcium (Ca/Ca) Technology: Calcium-alloyed plate grids minimize self-discharge and electrolyte evaporation. The battery is completely maintenance-free.

Increased Cranking Current: High cold cranking power allows for instant starting of 2.5-3.5-liter diesel engines.

Deep Discharge Resistance: The optimized composition of the active plate mass allows the battery to quickly restore charge after operating under high loads.

Safety and Sealed: The labyrinth lid system with integrated flame arrestors prevents electrolyte leaks and ensures explosion safety.

Control Indicator: The built-in "Magic Eye" allows you to visually assess the battery's charge level at any time.
