Product details
The CSB XTV1272WTFR is a 12V valve-regulated sealed lead-acid battery belonging to the XTV-WT series. It utilizes AGM absorbed glass mat technology, achieving gas recombination efficiency of up to 99%, and features a maintenance-free design. This series is based on a pure lead construction, and is officially positioned as a VRLA-AGM pure lead battery suitable for demanding environments such as wind power, with official applications in renewable energy.
Regarding capacity performance, at 25°C and 1.75VPC, the battery has a 20-hour rate nominal capacity of 7.2Ah, a 20-hour rate actual capacity of 7.40Ah, and an 8-hour rate capacity of 6.72Ah; when conditions change to 1.80VPC, the 8-hour rate capacity is 6.56Ah. Its maximum charging current is 2.16A, maximum discharging current is 130A, short-circuit current is 305A, and internal resistance is 20.40mΩ.
For charging, at 25°C, the float charging voltage is 13.5 to 13.8Vdc, and the equalization charging voltage is 14.4 to 15.0Vdc. Operating temperature range: -20°C to 50°C for discharge and charge, -15°C to 40°C for storage, with a nominal operating temperature of 25°C. In terms of self-discharge characteristics, storage at 25°C for 90 days results in less than 10% capacity loss, and the battery can be stored for up to 6 months, requiring a full charge before use; if storage temperature exceeds 25°C, recharge should be performed earlier.
In terms of construction, the battery case uses ABS flame-retardant material meeting 94-V0 rating, and the terminal type is F2 Faston Tab 250. Dimensions are length 150.9±2.0mm, width 64.8±1.0mm, height 98.6±1.0mm, and weight approximately 2.57kg. For design life, under 25°C float charging conditions it can reach 12 years, and under the Eurobat 20°C standard it is rated as 10 to 12 years long life. The product is manufactured according to IEC 61056-1/2:2012 and recognized under UL1989 (MH14533).
Based on the above features, this battery is suitable for energy storage and backup power in renewable energy systems, particularly for demanding applications such as wind power. Its maintenance-free and low self-discharge characteristics facilitate long-term deployment. For specific installation and charging settings, please refer to the official technical documentation.
