Product details

The CSB HR12120W is a high-rate discharge pure lead battery in the HR series, belonging to the 12V top terminal Valve Regulated Sealed Lead Acid type, officially designated for data center uninterruptible power supplies. This series is designed for UPS with lower output power and backup scenarios requiring rapid discharge. The battery combines a Valve Regulated Sealed Lead Acid structure with Absorbent Glass Mat technology, achieving a gas recombination efficiency of up to 99% and requiring no maintenance; the pure lead construction and proprietary element formula make it suitable for high-rate UPS and float backup power. Electrically, the HR12120W has a voltage of 12 Vdc and a nominal capacity of 120W @15min-rate (1.67 VPC @25°C). The 5-minute rate power is 232.17 W/cell, and the 15-minute rate power is 123 W/cell (both at 1.67 VPC @25°C). Maximum charge current is 12 A, maximum discharge current is 225 A, short-circuit current is 928 A, and internal resistance is 8.2 mΩ. Float charge voltage is 13.5 to 13.8 Vdc/battery (25°C), and equalize charge voltage is 14.4 to 15.0 Vdc/battery (25°C). Mechanically, the terminal is an I1-Thread lead alloy recessed terminal to accept M5 bolt, with torque of 30.4±6.1 Kgf·cm, 26.4±5.3 Lbf·in, or 3.0±0.6 N·m. The case is ABS (UL 94-HB), and a flame-retardant (94-V0) version is available upon request. Weight is 10.2 kg (20.48 lb), and dimensions are length 166±2.0 mm, width 125±1.5 mm, height 175±2.0 mm. Temperature characteristics: nominal temperature 25°C, discharge range -15°C to 50°C, charge and storage range -15°C to 40°C. Design life is 5 years under 25°C float standby conditions, and Eurobat (20°C) standard commercial life is 3 to 5 years. Self-discharge is less than 10% after 90 days, and it can be stored for up to 6 months at 25°C; it must be fully charged before use. If storage temperature exceeds 25°C, charge it in advance. The product is manufactured to IEC 61056-1/2:2012 and is UL1989 Recognized (MH14533).
