RIGEL AKU 190Ah Battery (Super Heavy Duty 2025)
The RIGEL AKU 190Ah is the flagship model in the commercial vehicle segment, designed to ensure maximum reliability in the harshest conditions. The 2025 version is optimized for modern truck life support systems (autonomous heaters, refrigerators, multimedia), ensuring reliable engine starting after extended periods of storage.

Key advantages of the 2025 model
SHD (Super Heavy Duty) Technology: Reinforced plate assembly fastening and the use of special fiberglass separators (Glass Mat) prevent active mass shedding even under extreme vibration.

Increased Cycle Endurance: The new 2025 active mass formula allows for 2.5 times more discharge/charge cycles than standard starter batteries.

Ca/Ca + Silver Technology: The use of a silver-calcium alloy minimizes self-discharge and eliminates water loss (completely maintenance-free design).

Anti-Freeze System: High energy density and optimized electrolyte composition ensure reliable cold starting of large-displacement diesel engines at temperatures down to -45°C.

Completely Sealed: A labyrinth cover with a gas recombination system and integrated flame arrestors ensures safety and leakage protection when tilted.
