Product details
The official application area for the CSB HRL1234W is data center uninterruptible power supplies; it can also be used for high-rate UPS and float standby power supplies. Data centers with higher load requirements and uninterruptible power supply applications are the direction this series is aimed at. This model belongs to the HRL series, is a valve-regulated sealed lead-acid battery, features 6V and 12V top terminal configurations, and has a rated voltage of 12 Vdc; the HRL series is positioned as long-life, high-rate pure lead batteries.
In terms of construction, the HRL1234W uses Absorbent Glass Mat (AGM) technology and a valve-regulated sealed lead-acid design, with a gas recombination efficiency of up to 99%, so it is maintenance-free; pure lead construction and a proprietary element formula are also used. The case material is ABS (UL 94-HB); a flame-retardant 94-V0 version is available upon request; the terminal type is F2 terminal - Faston Tab 250. The product is manufactured in accordance with IEC 61056-1/2:2012 and is UL1989 Recognized (MH14533).
Dimensions and weight: length 150.9±2.0 mm, width 64.8±1.0 mm, height 98.6±1.0 mm, weight 2.70 kg. In terms of design life, it can reach 8 years under 25°C float standby service; according to Eurobat (20°C) standards, commercial life is 10 to 12 years. Nominal operating temperature 25°C; discharge temperature range -15°C to 50°C; charge and storage temperature range -15°C to 40°C.
Capacity and power data are as follows: at 25°C and 1.67 VPC, nominal capacity 34W @15min-rate; power per cell under the same conditions is 75.34 W/cell at the 5-minute rate and 35.50 W/cell at the 15-minute rate. Maximum charge current 3.40 A, maximum discharge current 130 A; short-circuit current 367 A, internal resistance 17.0 mΩ.
At 25°C, float voltage is 13.5 to 13.8 Vdc/battery, and equalization voltage is 14.4 to 15.0 Vdc/battery. In a 25°C environment, self-discharge is less than 10% after 90 days, and it can be stored for up to 6 months; fully charge before use, and if storage temperature is higher than 25°C, charge sooner. This battery is suitable for high-rate UPS and float standby power applications.
