Product details
The CSB HRL1210W belongs to the HRL series, a valve-regulated sealed lead-acid battery available in 6V and 12V top terminal configurations, with a nominal voltage of 12 Vdc. This series is designed for long-life, high-rate UPS and data center loads, featuring pure lead construction and a proprietary formulation, combined with absorbed glass mat technology, achieving up to 99% gas recombination efficiency in a maintenance-free design.
In terms of capacity and power performance, the HRL1210W provides a 15-minute rate nominal capacity of 10W at 25°C and 1.67 VPC; the 5-minute rate power is 20.7 W/cell, and the 15-minute rate power is 10.0 W/cell. Electrically, 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. The float charge voltage is 13.5 to 13.8 Vdc/battery (25°C), and the equalizing charge voltage is 14.4 to 15.0 Vdc/battery (25°C).
In terms of dimensions and terminals, the battery length is 178.0±2.0 mm, width is 34.0±1.0 mm, height is 70.5±1.0 mm, and weight is 1.10 kg. The terminal type is F2 terminal - Faston Tab 250. The case material is ABS (UL 94-HB), with a flame-retardant 94-V0 version available upon request.
Regarding temperature and storage characteristics, the nominal operating temperature is 25°C, the discharge temperature range is -15°C to 50°C, and the charge and storage temperature range is -15°C to 40°C. For self-discharge, capacity loss is less than 10% after 90 days of storage at 25°C, and storage at 25°C is possible for up to 6 months, requiring a full charge before use; if storage temperature exceeds 25°C, recharge should be performed sooner.
The product has a design life of up to 8 years in float standby service at 25°C, and 10 to 12 years per the Eurobat (20°C) standard for commercial use. The product is manufactured in accordance with IEC 61056-1/2:2012 and is UL1989 recognized (MH14533), suitable for high-rate float standby power applications such as data center UPS.
