Description

The ARIET 6GFM-55 battery is manufactured using AGM (Absorbent Glass Mat) technology and is designed for use in backup and uninterruptible power supply systems. Its sealed VRLA design ensures that up to 99% of the gas released is recombined, making the battery safe and maintenance-free.

The battery’s nominal voltage is 12 V, and its capacity is 55 Ah. Thanks to the high density of the grid structure and the use of high-quality materials, the battery offers stable performance, low self-discharge, and a long service life of up to 10–12 years in buffer mode.

The casing is made of durable, flame-retardant ABS plastic, which enhances operational safety. The internal resistance of a fully charged battery is approximately 7.0 mΩ, ensuring efficient energy delivery.

The battery is designed to operate over a wide temperature range: discharge from −20°C to +60°C, charge from −10°C to +50°C, and storage down to −20°C. It supports high charge currents of up to 16.5 A and maintains stable performance under various operating conditions.

The battery’s dimensions are 229 × 138 × 211 mm, with a height of 216 mm including terminals, and a weight of approximately 17.5 kg. The terminals are M6 bolts, ensuring a reliable connection.

Thanks to its high reliability, energy capacity, and safety, the ARIET 6GFM-55 battery is the optimal solution for professional backup power systems where stable and long-lasting equipment operation is required.
