Product details
The CSB HRL1225W is a 12V Valve Regulated Sealed Lead Acid battery in the HRL series. It uses Absorbent Glass Mat (AGM) technology with gas recombination efficiency of up to 99%, and features a pure lead construction with a proprietary element formula. The series is positioned for high-rate UPS and float standby power, with data center uninterruptible power supplies listed as the official application.
In terms of specifications, the HRL1225W has a nominal capacity of 25W @15-minute rate, tested at 1.67VPC, 25°C. The 5-minute rate power is 54.16 W/cell, and the 15-minute rate power is 25.67 W/cell. Its maximum charge current is 2.50 A, maximum discharge current is 130 A, short-circuit current is 328 A, and internal resistance is 19.60 mΩ. The float charge voltage range is 13.5 to 13.8 Vdc/battery (25°C), and the equalize charge voltage range is 14.4 to 15.0 Vdc/battery (25°C).
Dimensions and terminals: the battery measures 90.0±1.0 mm in length, 70.0±1.0 mm in width, and 106.1±1.5 mm in height, and weighs 1.95 kg (4.30 lb). The terminal is F2 terminal - Faston Tab 250. The case material is ABS (UL 94-HB), and a flame-retardant (94-V0) version is available on request.
For temperature conditions, the nominal temperature is 25°C (77°F); discharge is permitted from -15°C to 50°C (5°F to 122°F), and charge and storage are permitted from -15°C to 40°C (5°F to 104°F). Self-discharge performance: after 90 days at 25°C, self-discharge is less than 10%, and storage is possible for up to 6 months; the battery should be fully charged before being put into service, and if the storage temperature exceeds 25°C, a supplementary charge is required in advance.
In terms of life design, it can be used for 8 years under float charge at 25°C; according to the Eurobat (20°C) standard, it is 10 to 12 years. The product is manufactured in accordance with IEC 61056-1/2:2012 and is UL1989 recognized (MH14533). With its maintenance-free construction and high-rate discharge performance, the HRL1225W is well suited for scenarios requiring reliable backup power, such as data center UPS.
