Product details
HRL634W is a member of the HRL series, which covers 6V and 12V top terminal VRLA-AGM batteries and is officially designated for data center uninterruptible power supplies. The series is positioned for long-life, high-rate UPS pure lead batteries, targeting high-power data centers and UPS loads. Its design combines a valve regulated sealed lead acid structure with absorbed glass mat technology, achieving gas recombination efficiency of up to 99% and maintenance-free operation; it is manufactured with pure lead construction and a proprietary element formula for use in high-rate UPS float standby power applications.
In terms of appearance and construction, the HRL634W is equipped with F2 terminals, also known as Faston Tab 250. The case uses ABS (UL 94-HB), and a flame-retardant 94-V0 version can also be provided when required. Weight is 1.32 kg (2.91 lb). Dimensions are: length 150.9±2.0 mm (5.94±0.08 in), width 34.0±1.0 mm (1.34±0.04 in), height 98.6±1.0 mm (3.88±0.04 in).
Electrically, the battery has a rated voltage of 6 Vdc; at 1.67 VPC and 25°C, the nominal capacity at the 15-minute rate is 34W. Among the per-cell power data, the 30-second, 1.67 VPC, 25°C condition is not listed in the documentation; at 5 minutes, 1.67 VPC, 25°C it is 36.33 W/cell; at 15 minutes, 1.67 VPC, 25°C it is 18.17 W/cell. Current and internal resistance specifications are as follows: maximum charge current 3.40 A, maximum discharge current 130 A, short-circuit current 380 A, internal resistance 8.30 mΩ. At 25°C, the float voltage range is 6.75 to 6.90 Vdc/battery, and the equalization voltage range is 7.20 to 7.50 Vdc/battery.
For life and temperature, the design life under 25°C float standby is up to 8 years; the Eurobat (20°C) standard commercial life is 10 to 12 years. 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 are permitted from -15°C to 40°C (5°F to 104°F). For self-discharge, it is less than 10% after 90 days; storage at 25°C (77°F) can last up to 6 months. It must be fully charged before re-use, and if the storage temperature exceeds 25°C (77°F), earlier charging is required.
This product is manufactured in accordance with IEC 61056-1/2:2012 and has UL1989 recognition (MH14533). Based on the above characteristics, the HRL634W is suitable for scenarios such as data center UPS that require both high-rate discharge and float standby, and its design and performance can be demonstrated at 25°C.
