Product details

XTV12120WTFR is part of the CSB XTV-WT product line and is offered as a 12V valve-regulated sealed lead-acid battery. The battery uses an AGM absorbent glass mat separator design, can achieve gas recombination efficiency of up to 99%, and is manufactured with a pure lead construction combined with proprietary elements. The officially listed application is renewable energy, especially for demanding conditions such as wind power generation. In terms of physical dimensions, length, width, and height are 151.0±2.0 mm, 98.0±1.0 mm, and 101.8±1.5 mm respectively, and the overall weight is 4.10 kg. The case material is flame-retardant ABS (94-V0), and the terminal is F2 Faston Tab 250. For electrical data, at 1.75 VPC and 25°C, the 20-hour rate corresponds to a nominal capacity of 12 Ah and the 8-hour rate corresponds to 11.3 Ah; if conditions are changed to 1.80 VPC, the 8-hour rate is 11.1 Ah. The maximum charge current is 3.60 A, maximum discharge current is 180 A, short-circuit current is 438 A, and internal resistance is 15.0 mΩ. For charging settings and operating temperature, float charge at 25°C requires 13.5 to 13.8 Vdc, and equalization charge requires 14.4 to 15.0 Vdc. The nominal operating temperature is 25°C; discharge and charge are permitted from -20°C to 50°C, and storage is permitted from -15°C to 40°C. For life and storage characteristics, the design life is up to 12 years under 25°C float charge, and the Eurobat (20°C) rating is 10/12-year long life. Self-discharge is less than 10% after 90 days; it can be stored for up to 6 months at 25°C and must be fully charged before use; if storage temperature exceeds 25°C, supplementary charging is required earlier. This product is manufactured in accordance with IEC 61056-1/2:2012 and has obtained UL1989 recognition (MH14533). It can be used for renewable energy storage and is also suitable for wind power-related applications.
