Product details
The CSB HRL1210W belongs to the HRL series and uses 6V and 12V top terminal configurations. It is a valve-regulated sealed lead-acid battery with a nominal voltage of 12 Vdc. The series is designed for long-life, high-rate UPS and data center loads. Internally, it uses a pure lead construction and a proprietary formulation, combined with absorbed glass mat technology, with gas recombination efficiency of up to 99%, and an overall maintenance-free design.
In terms of dimensions and terminals, the battery is 178.0±2.0 mm long, 34.0±1.0 mm wide, and 70.5±1.0 mm high, with a weight of 1.10 kg; the terminal type is F2 terminal - Faston Tab 250. The case material is ABS (UL 94-HB), and a flame-retardant 94-V0 version can also be supplied on request.
For temperature and storage, the nominal operating temperature is 25°C, the discharge range is -15°C to 50°C, and the charge and storage range is -15°C to 40°C. In terms of self-discharge, capacity loss is less than 10% after 90 days of storage at 25°C; the battery can be stored for up to 6 months at 25°C and must be fully charged before use. If the storage temperature is higher than 25°C, supplementary charging is required sooner.
At 25°C and 1.67 VPC, the HRL1210W has a 15-minute rate nominal capacity of 10W; in terms of power, the 5-minute rate is 20.7 W/cell and the 15-minute rate is 10.0 W/cell. In terms of electrical specifications, the maximum charge current is 1.0 A, the maximum discharge current is 40 A, the short-circuit current is 120 A, and the internal resistance is 32.10 mΩ. At 25°C, the float charge voltage range is 13.5 to 13.8 Vdc/battery, and the equalization charge voltage range is 14.4 to 15.0 Vdc/battery.
The product has a design life of up to 8 years in 25°C float standby service; under the Eurobat (20°C) standard, commercial use is 10 to 12 years. It is manufactured in accordance with IEC 61056-1/2:2012 and recognized under UL1989 (MH14533), and can be used in high-rate float standby power applications such as data center UPS.
