Product details
The CSB HRL1210W is part of the HRL series, available in both 6V and 12V top terminal configurations. It is a valve-regulated sealed lead acid battery with a nominal voltage of 12 Vdc. Designed for UPS and data center loads requiring long life and high-rate performance, this series uses a pure lead construction with a proprietary formula and absorbed glass mat technology, achieving up to 99% gas recombination efficiency in a maintenance-free design.
In terms of capacity and power, the HRL1210W delivers a nominal capacity of 10W at the 15-minute rate at 25°C and 1.67 VPC, and 20.7 W/cell at the 5-minute rate with 10.0 W/cell at the 15-minute rate. Electrical specifications include a maximum charge current of 1.0 A, maximum discharge current of 40 A, short-circuit current of 120 A, and internal resistance of 32.10 mΩ. Float voltage at 25°C ranges from 13.5 to 13.8 Vdc/battery, while equalize voltage is 14.4 to 15.0 Vdc/battery (25°C).
Dimensions and terminals: the battery measures 178.0±2.0 mm in length, 34.0±1.0 mm in width, and 70.5±1.0 mm in height, weighing 1.10 kg. It features an F2 terminal - Faston Tab 250. The case material is ABS (UL 94-HB), with a flame-retardant 94-V0 version available upon request.
Temperature and storage conditions: nominal operating temperature is 25°C, discharge temperature range is -15°C to 50°C, and charge and storage temperature range is -15°C to 40°C. For self-discharge, capacity loss is less than 10% after 90 days at 25°C, with a maximum storage of 6 months at 25°C; a full charge is required before use. If storage temperature exceeds 25°C, a supplementary charge is needed sooner.
In terms of design life, it offers up to 8 years in float standby service at 25°C, and 10 to 12 years per Eurobat (20°C) standard for commercial use. Manufactured in accordance with IEC 61056-1/2:2012 and recognized under UL1989 (MH14533), it is suitable for high-rate float standby power applications such as data center UPS systems.
