GFM-3000

Product catalog summary

Main Applications: The GFM-3000 Series VRLA Battery is designed for backup power in telecom and signal systems, electric systems, nuclear plants, military and maritime equipment, UPS, and emergency lighting. It also serves as storage for solar, wind, and hydroelectric energy.

Technical Parameters: The battery has a nominal voltage of 2V and a capacity of 3000 Ah at 10 hours to 1.80 V at 25˚C. It weighs 170 kg and has dimensions of 568 mm in length, 363 mm in width, and 369 mm in height, with a total height of 388 mm. The internal resistance when fully charged is 0.17 mΩ, and it can deliver a short-circuit current of 28000 A. The self-discharge rate is less than 3% after 30 days at 25˚C.

Operating Conditions: The battery operates in a temperature range of -40˚C to 50˚C for discharge, -20˚C to 45˚C for charge, and -20˚C to 40˚C for storage. The recommended operating temperature is between 15˚C and 25˚C. The recommended charging current is 450 A, with a float charging voltage of 2.23 V/cell and an equalize charging voltage of 2.35 V/cell.

Benefits: The battery offers reduced operational costs, excellent deep cycling performance, reduced CO2 emissions, and a long life of 15 years. It is certified under ISO9001, ISO14001, ISO18001, UL, and CE standards.

Technical Features: The battery exhibits good performance for charge acceptability, excellent capacity retention, and recovery performance. It is designed for both cyclic and float applications.

Performance Characteristics: The battery's capacity varies with temperature, maintaining 106% at 40˚C, 80% at 0˚C, and 50% at -20˚C. The charge time for 50% capacity is 100 hours. The document includes performance curves for constant current and power discharge characteristics at 25˚C.

Additional Information: The battery's container is made of ABS or optional ABS V0 material. The document notes that specifications are subject to change without notice and advises contacting CHINASHOTO for the latest information.
