Product details

The CSB XTV1285 is a 12V valve regulated sealed lead acid battery in the XTV series and belongs to the pure lead series. It is intended for the telecom broadband sector and is suitable for both indoor and outdoor environments; the terminal configuration is Top Terminal, the separator uses AGM absorbent glass mat, and gas recombination efficiency can reach up to 99%. Current and internal resistance data are as follows: 2.55A is the maximum charging current, 130A is the maximum discharge current, short-circuit current is 288A, and internal resistance is 20.9mΩ. For capacity, under 25°C and 1.75VPC conditions, the 20-hour rate nominal capacity is 8.5Ah and the 20-hour rate capacity is 8.80Ah; at 8-hour rate discharge, 1.75VPC corresponds to 8.00Ah and 1.80VPC corresponds to 7.87Ah. The terminal is F2 Faston Tab 250. The case material is ABS (UL 94-HB); a flame-retardant (94-V0) version is also available when required. Dimensions are length 150.9±2.0mm, width 64.8±1.0mm, height 98.6±1.0mm, and weight approximately 2.62kg. Temperature and voltage: 25°C is the nominal operating temperature; the charge/discharge temperature range is -20°C to 50°C, and the storage temperature range is -15°C to 40°C. At this temperature, the float charge voltage is 13.5 to 13.8Vdc, and the equalization charge voltage is 14.4 to 15.0Vdc. Self-discharge is less than 10% after 90 days; it can be stored for up to 6 months at 25°C, and a full charge should be completed before use; if the storage environment exceeds 25°C, charging should be performed sooner. This battery is maintenance-free and can be used for float backup power, making it especially suitable for telecom backup power in extreme temperature environments. The design float life at 25°C is up to 12 years; under the Eurobat 20°C standard, it offers a 10/12-year long life. It is manufactured in accordance with IEC 61056-1/2:2012 and is recognized under UL1989 (MH14533).
