Description

Energy storage ARIET DTM 12100 — reliable sealed lead-acid power supply with rated voltage 12V and capacity 100 Ah. The model has an increased service life and is designed for the service life up to 10–12 years in buffer mode.

The overall dimensions of the battery are 330 × 171 × 220 mm (L/W/H), which allows it to be conveniently used in various backup power systems and power plants.

Batteries of the series ARIET DTM are fully sealed and maintenance free. They are equipped with a recombination of VRLA gases, which minimizes electrolyte loss and ensures safe operation.

Production of batteries is carried out according to the technology AGM (Absorbent Glass Mat)wherein the electrolyte is absorbed in a fiberglass separator. This design increases the vibration resistance of the battery, improves the stability of operation and ensures high reliability during long-term operation.

The DTM LongLife series is designed for equipment that requires a stable and long-lasting power source. These batteries are widely used in:

uninterruptible power supply (UPS) systems;
emergency and backup power supply systems;
heating system equipment (pumps, boilers);
telecommunications and electrical equipment;
various electronic and power devices.

Thanks to their high capacity, low internal resistance, and stable discharge characteristics, ARIET DTM batteries ensure reliable operation even for demanding electrical devices and professional power systems.
