Product details
The CSB HRL1234W is part of the HRL series and is a VRLA battery available with 6V and 12V top terminal configurations, with a nominal voltage of 12 Vdc. This series is positioned as long-life, high-rate pure lead batteries, primarily addressing data center and UPS applications with higher load demands; its official designated use is data center UPS.
For capacity and power, at 25°C and 1.67 VPC, the HRL1234W has a nominal capacity of 34W @15min-rate. Also at 25°C and 1.67 VPC, per-cell power is 75.34 W/cell at the 5-minute rate and 35.50 W/cell at the 15-minute rate. The battery's maximum charge current is 3.40 A, maximum discharge current is 130 A, short-circuit current is 367 A, and internal resistance is 17.0 mΩ.
In terms of construction, the battery uses VRLA design and absorbed glass mat technology, achieving up to 99% gas recombination for maintenance-free operation; it also features pure lead construction and a proprietary element formulation. The case material is ABS (UL 94-HB), with a flame-retardant 94-V0 version available on request. The terminal type is F2 terminal - Faston Tab 250. The product is manufactured to IEC 61056-1/2:2012 and is UL1989 Recognized (MH14533).
Dimensions and weight: the battery is 150.9±2.0 mm long, 64.8±1.0 mm wide, and 98.6±1.0 mm high, weighing 2.70 kg. Design life is up to 8 years in 25°C float standby service, and 10 to 12 years under the Eurobat (20°C) standard for commercial use. The nominal operating temperature is 25°C, with a discharge range from -15°C to 50°C and a charge and storage range from -15°C to 40°C.
For charging parameters, at 25°C the float voltage is 13.5 to 13.8 Vdc/battery and the equalize voltage is 14.4 to 15.0 Vdc/battery. Self-discharge is less than 10% after 90 days at 25°C, and the battery can be stored for up to 6 months; it must be fully charged before use, and if storage temperature exceeds 25°C, recharge is required sooner. This battery is suitable for high-rate UPS and float standby power applications.
