Product details
The CSB XTV1272WTFR belongs to the XTV-WT series and is a 12V valve-regulated sealed lead-acid battery using AGM absorbed glass mat technology, with a gas recombination efficiency of up to 99%, and a maintenance-free design. This series uses a pure lead construction and is officially positioned as a VRLA-AGM pure lead battery for harsh environments such as wind power, with official applications in renewable energy.
In terms of capacity, the battery has a 20-hour rate nominal capacity of 7.2Ah at 25°C and 1.75VPC, a 20-hour rate measured capacity of 7.40Ah, and an 8-hour rate capacity of 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.
For charging parameters, at 25°C the float charge voltage is 13.5 to 13.8Vdc, and the equalizing charge voltage is 14.4 to 15.0Vdc. The operating temperature range is -20°C to 50°C for discharge and charge, -15°C to 40°C for storage, with a nominal operating temperature of 25°C. For self-discharge, capacity loss is less than 10% after 90 days at 25°C, and it can be stored for up to 6 months; a full charge is required before use, and if the storage temperature is above 25°C, it should be charged sooner.
Structurally, the battery case uses ABS flame-retardant material meeting the 94-V0 rating, and the terminals are F2 Faston Tab 250 type. The dimensions are 150.9±2.0mm long, 64.8±1.0mm wide, and 98.6±1.0mm high, with a weight of approximately 2.57kg. The design life can reach 12 years under 25°C float charge service conditions, and 10 to 12 years long life level under the Eurobat 20°C standard. The product is manufactured according to IEC 61056-1/2:2012 and is recognized under UL1989 (MH14533).
Based on the above characteristics, this battery is suitable for energy storage and backup power in renewable energy systems, especially for application needs in harsh environments such as wind power. Its maintenance-free and low self-discharge characteristics make it convenient for long-term deployment, and specific installation and charging settings should be carried out in accordance with official technical documentation.
