Product details

The CSB XTV1285 is a 12V Valve Regulated Sealed Lead Acid battery in the XTV series, featuring a Top Terminal design and AGM Absorbent Glass Mat technology, with gas recombination efficiency of up to 99%. This series belongs to the pure lead series and is mainly aimed at telecom broadband applications, suitable for both indoor and outdoor environments. In terms of capacity parameters, the XTV1285 at 25°C and 1.75VPC has a 20-hour rate nominal capacity of 8.5Ah and a 20-hour rate capacity of 8.80Ah; the 8-hour rate 1.75VPC capacity is 8.00Ah, and the 8-hour rate 1.80VPC capacity is 7.87Ah. The maximum charge current is 2.55A, the maximum discharge current is 130A, the short-circuit current is 288A, and the internal resistance is 20.9mΩ. In terms of dimensions and terminals, the battery is 150.9±2.0mm long, 64.8±1.0mm wide, and 98.6±1.0mm high, weighing approximately 2.62kg. The terminal type is F2 Faston Tab 250. The case is made of ABS material (UL 94-HB), and a flame-retardant (94-V0) version can also be provided on request. Charging and temperature conditions: at 25°C, the float charge voltage is 13.5 to 13.8Vdc, and the equalization charge voltage is 14.4 to 15.0Vdc. The nominal operating temperature is 25°C, the discharge and charge temperature range is -20°C to 50°C, and the storage temperature range is -15°C to 40°C. 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 the storage temperature exceeds 25°C, it needs to be charged earlier. This product features a maintenance-free design and is suitable for float charge backup power scenarios, especially for telecom backup power in extreme temperature environments. Under 25°C float charge conditions, the design life can reach 12 years; under the Eurobat 20°C standard, it is 10/12 years long life. The product is manufactured in accordance with IEC 61056-1/2:2012 and has obtained UL1989 recognition (MH14533).
