Product details

The CSB XTV12120 belongs to the XTV Pure Lead series and is a 12V Valve Regulated Sealed Lead Acid battery, officially positioned as a VRLA pure lead product for telecom broadband applications, suitable for both indoor and outdoor environments. The nominal capacity is 12 Ah (20-hour rate, 1.75 VPC @25°C); at the 8-hour rate, the capacity is 11.2 Ah (1.75 VPC @25°C) or 11.1 Ah (1.80 VPC @25°C). The battery uses Absorbent Glass Mat (AGM) technology, achieves up to 99% gas recombination efficiency, is maintenance-free, and features a pure lead construction with proprietary elements. In terms of electrical parameters, the XTV12120 has a float charge voltage of 13.5 - 13.8 Vdc/cell at 25°C and an equalize charge voltage of 14.4 - 15.0 Vdc/cell. The maximum charge current is 3.60 A, the maximum discharge current is 180 A, the short-circuit current is 438 A, and the internal resistance is 15.0 mΩ. Under float charge at 25°C, the design life reaches up to 12 years, meeting the Eurobat long life standard (10/12 years at 20°C). The self-discharge rate is low: stored at 25°C for 90 days, self-discharge is less than 10%, and storage is possible for up to 6 months; however, a full charge is required before use, and if the storage temperature exceeds 25°C, charging should be done earlier. Mechanical dimensions: the battery is 151.0±2.0 mm long, 98.0±1.0 mm wide, 101.8±1.5 mm high, and weighs 4.10 kg (9.02 lb). The terminal is F2 Faston Tab 250. The case is made of ABS (UL 94-HB) material, and a flame-retardant (94-V0) version can also be provided on request. Operating temperature range: nominal 25°C; discharge and charge from -20°C to 50°C; storage from -15°C to 40°C. The XTV12120 is built for float charge backup power applications in extreme temperature environments and is suitable for the telecom field. With its pure lead construction and AGM technology, it provides reliable backup power in outdoor or indoor environments. The battery complies with IEC 61056-1/2:2012 and is recognized under UL1989 (MH14533).
