Product details
The CSB HRL634W is a product in the HRL series, a 6V, 12V top-terminal VRLA-AGM battery officially designated for data center uninterruptible power supplies. The series is positioned as a long-life, high-rate UPS pure lead battery, specifically designed for high-power data center and UPS loads. Its construction uses valve-regulated sealed lead-acid with absorbed glass mat technology, achieving gas recombination efficiency of up to 99% with no maintenance required during use; it is also made with a pure lead construction and proprietary element formulation, making it suitable for high-rate UPS float standby power scenarios.
In terms of electrical parameters, the HRL634W has a voltage of 6 Vdc; at 1.67 VPC, 25°C, its nominal capacity at the 15-minute rate is 34W. The per-cell power at 30 seconds, 1.67 VPC, 25°C is not provided in the official 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. Maximum charge current is 3.40 A, maximum discharge current is 130 A, short-circuit current is 380 A, and internal resistance is 8.30 mΩ. Float voltage at 25°C is 6.75 to 6.90 Vdc/battery, and equalize voltage at 25°C is 7.20 to 7.50 Vdc/battery.
In terms of dimensions and construction, the HRL634W features an F2 terminal, also known as Faston Tab 250. The case material is ABS (UL 94-HB), with a flame-retardant 94-V0 version available upon request. The battery weighs 1.32 kg (2.91 lb); length is 150.9±2.0 mm (5.94±0.08 in), width is 34.0±1.0 mm (1.34±0.04 in), and height is 98.6±1.0 mm (3.88±0.04 in).
Regarding environmental adaptability and service life, the design life can reach up to 8 years under 25°C float standby conditions; according to the Eurobat (20°C) standard, commercial life is 10 to 12 years. The nominal operating temperature is 25°C (77°F), discharge is permitted from -15°C to 50°C (5°F to 122°F), and charging and storage from -15°C to 40°C (5°F to 104°F). Self-discharge is less than 10% after 90 days, and the battery 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 exceeds 25°C (77°F), it should be charged earlier.
