RIGEL AKU 75Ah PES TERS Battery (Advanced Power Series)
The RIGEL AKU 75Ah PES TERS is a high-tech power source that combines a Power Efficiency System (PES) with enhanced internal component reliability. The TERS model is optimized for frequent engine starts and short city trips, ensuring rapid charge acceptance and long battery life.

Key Advantages of the PES TERS Series
PES (Power Efficiency System) Technology: The special grid geometry of the plates reduces internal resistance, ensuring instantaneous current delivery during cold starts.

Ca/Ca (Calcium) Technology: The use of purified calcium alloy minimizes self-discharge and eliminates water loss (maintenance-free design).

Improved vibration resistance (Tersus Build): Reinforced plate assembly mounting protects the active mass from shedding when driving on rough roads and under intense diesel engine vibration.

Fast charging: The battery recovers its capacity more quickly after a deep cranking, which is critical for vehicles with a start-stop system (basic level) or extensive electronics.

Safe operation: A labyrinth cover with integrated flame arrestors prevents electrolyte leakage and ensures explosion safety.
