Product details
In renewable energy system energy storage and backup power applications, the CSB XTV1272WTFR can serve demanding environments such as wind power generation. It belongs to the XTV-WT series and is a 12V valve-regulated sealed lead-acid battery, featuring AGM absorbed glass mat technology, a maintenance-free design, and gas recombination efficiency of up to 99%. The series has a pure lead construction, and it is officially positioned as a VRLA-AGM pure lead battery for demanding environments such as wind power generation; its officially listed application area is renewable energy.
In terms of construction, the case is made of flame-retardant ABS material and meets the 94-V0 rating, and the terminals use the F2 Faston Tab 250 type. Dimensions are length 150.9±2.0mm, width 64.8±1.0mm, and height 98.6±1.0mm, with a weight of approximately 2.57kg. Under 25°C float charge conditions, the design life can reach 12 years; according to the Eurobat 20°C standard, it falls into the 10- to 12-year long-life category. The product is manufactured in accordance with IEC 61056-1/2:2012 and is UL1989 recognized (MH14533).
For capacity and current, at 25°C and 1.75VPC, the nominal capacity at the 20-hour rate is 7.2Ah, the measured capacity at the 20-hour rate is 7.40Ah, and the 8-hour rate capacity is 6.72Ah; at 1.80VPC, the 8-hour rate capacity is 6.56Ah. Maximum charge current is 2.16A, maximum discharge current is 130A, short-circuit current is 305A, and internal resistance is 20.40mΩ.
For charging and temperature, 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 operating temperature range for discharge and charge is -20°C to 50°C, the storage temperature is -15°C to 40°C, and the nominal operating temperature is 25°C. For self-discharge, after 90 days at 25°C the capacity loss is less than 10%, and it can be stored for up to 6 months; it should be fully charged before use, and if the storage temperature is above 25°C, charging is required sooner.
The maintenance-free and low self-discharge characteristics make it suitable for long-term deployment; specific installation and charging settings should be based on official technical documentation.
