Product details
The CSB HRL634W belongs to the HRL series, with product types being 6V and 12V top terminal VRLA-AGM batteries, and its official application area is data center uninterruptible power supplies. This series is positioned as a long-life, high-rate UPS pure lead battery series, designed for high-power data centers and UPS loads. The battery adopts a valve-regulated sealed lead-acid structure and absorbed glass mat technology, with gas recombination efficiency of up to 99%, requires no maintenance, and is manufactured with pure lead construction and a proprietary element formula, suitable for high-rate UPS float standby power applications.
In terms of electrical parameters, the HRL634W has a voltage of 6 Vdc, and its nominal capacity is 34W at the 15-minute rate under 1.67 VPC at 25°C. The per-cell power at 30 seconds, 1.67 VPC, 25°C is not provided in the data; at 5 minutes, 1.67 VPC, 25°C it is 36.33 W/cell, and at 15 minutes, 1.67 VPC, 25°C it is 18.17 W/cell. The maximum charging current is 3.40 A, the maximum discharge current is 130 A, the short-circuit current is 380 A, and the internal resistance is 8.30 mΩ. The float charge voltage is 6.75 to 6.90 Vdc/battery (25°C), and the equalizing charge voltage is 7.20 to 7.50 Vdc/battery (25°C).
In terms of construction and dimensions, the HRL634W uses an F2 terminal, i.e., Faston Tab 250. The case material is ABS (UL 94-HB), and a flame-retardant 94-V0 version can be provided upon request. The battery weight is 1.32 kg, i.e., 2.91 lb; the length is 150.9±2.0 mm, i.e., 5.94±0.08 in; the width is 34.0±1.0 mm, i.e., 1.34±0.04 in; and the height is 98.6±1.0 mm, i.e., 3.88±0.04 in.
In terms of environment and life, the design life is up to 8 years under 25°C float standby conditions, and 10 to 12 years for Eurobat (20°C) standard commercial use. The nominal operating temperature is 25°C (77°F), discharge is -15°C to 50°C (5°F to 122°F), and charging and storage are -15°C to 40°C (5°F to 104°F). Self-discharge is less than 10% after 90 days, and it can be stored for up to 6 months at 25°C (77°F); it must be fully charged before use, and if the storage temperature is above 25°C (77°F), it should be charged earlier.
The product is manufactured in accordance with IEC 61056-1/2:2012 and is recognized under UL1989 (MH14533). These features make the HRL634W suitable for applications such as data center UPS that require high-rate discharge and float standby, allowing it to deliver its design and performance at 25°C.
