Product details
The CSB XTV1272WTFR is a 12V Valve Regulated Sealed Lead Acid battery in the XTV-WT series. It utilizes AGM Absorbent Glass Mat technology with a gas recombination efficiency of up to 99% and a maintenance-free design. Based on a pure lead structure, the manufacturer positions this series as VRLA-AGM pure lead batteries suitable for harsh environments such as wind power generation, with official applications designated for renewable energy.
In terms of capacity, at 25°C and 1.75VPC, the 20-hour rate nominal capacity is 7.2Ah, the 20-hour rate actual capacity reaches 7.40Ah, and the 8-hour rate capacity is 6.72Ah; at 1.80VPC, the 8-hour rate capacity is 6.56Ah. The maximum charge current is 2.16A, the maximum discharge current is 130A, the short-circuit current is 305A, and the internal resistance is 20.40mΩ.
Regarding charge settings, at 25°C the float charge voltage ranges from 13.5 to 13.8Vdc, and the equalization charge voltage ranges from 14.4 to 15.0Vdc. Operating temperature range: -20°C to 50°C for both discharge and charge, storage temperature is -15°C to 40°C, and nominal operating temperature is 25°C. For self-discharge characteristics, storage at 25°C for 90 days results in less than 10% capacity loss, with a maximum storage of 6 months; fully charge before use. If storage temperature exceeds 25°C, charge in advance.
The battery case is made of ABS flame-retardant material meeting 94-V0 rating, with F2 Faston Tab 250 terminals. Dimensions: length 150.9±2.0mm, width 64.8±1.0mm, height 98.6±1.0mm, weight approximately 2.57kg. Design life can be up to 12 years at 25°C float charge, and according to the Eurobat 20°C standard, it falls into the 10 to 12-year long life category. The product is manufactured to IEC 61056-1/2:2012 and recognized under UL1989 (MH14533).
Based on the above features, this battery can be used for energy storage and backup power in renewable energy systems, and is particularly suitable for applications in harsh environments such as wind power generation. The advantages of maintenance-free operation and low self-discharge make it suitable for long-term deployment.
