Product details

The CSB XTV12120WTFR is a product in the XTV-WT series and is a 12V Valve Regulated Sealed Lead Acid Battery. It uses AGM Absorbent Glass Mat technology with a gas recombination efficiency of up to 99%, and is manufactured with a pure lead construction combined with proprietary elements. This series is designed for demanding environments such as wind power, and its officially positioned application area is renewable energy. In terms of capacity, at 25°C and 1.75 VPC, the 20-hour rate nominal capacity is 12 Ah, and the 8-hour rate capacity is 11.3 Ah; at 1.80 VPC, the 8-hour rate capacity is 11.1 Ah. 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. For dimensions and terminals, the battery is 151.0±2.0 mm long, 98.0±1.0 mm wide, and 101.8±1.5 mm high, and weighs 4.10 kg. The case is made of flame-retardant ABS (94-V0), and the terminal is the F2 Faston Tab 250 type. For charging and temperature, at 25°C the float charge voltage is 13.5 to 13.8 Vdc, and the equalize charge voltage is 14.4 to 15.0 Vdc. 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. When used in float charge at 25°C, the design life can reach 12 years, with a Eurobat (20°C) 10/12-year long life rating. 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 should be charged earlier. This product is manufactured in accordance with IEC 61056-1/2:2012 and is recognized under UL1989 (MH14533). It is suitable for renewable energy storage and wind power-related scenarios.
