Product details
XTV12200WTFR is a valve regulated sealed lead-acid battery under the CSB brand, with a rated voltage of 12V, belonging to the XTV-WT series. Its construction is built with pure lead combined with proprietary elements, and it uses absorbent glass mat (AGM) technology, achieving a gas recombination efficiency of 99%. For the renewable energy field, this product is officially positioned as a suitable power source for harsh operating conditions such as wind turbines. Capacity: at 25°C, 1.75VPC, 20-hour rate, the nominal value is 20Ah; at the 8-hour rate, it is 18.4Ah at 1.75VPC and 18.0Ah at 1.80VPC.
In terms of electrical parameters, the maximum charge current is 6.0A, the maximum discharge current is 230A, the short-circuit current is 591A, and the internal resistance is 12.2mΩ. At 25°C, the float charge voltage range is 13.5 to 13.8Vdc, and the equalization charge voltage range is 14.4 to 15.0Vdc. The battery has low self-discharge: after standing for 90 days at 25°C, the remaining capacity remains above 90%; it can be stored for up to 6 months. However, it must be fully charged before being put into service; if the storage temperature exceeds 25°C, supplementary charging is required sooner.
Under float charging at 25°C, the design life can reach 12 years, meeting the Eurobat long-life standard (10/12 years at 20°C). The temperature range is: nominal 25°C; both discharge and charge support -20°C to 50°C; storage environment is -15°C to 40°C. The case is made of flame-retardant ABS material (94-V0). The terminal is an I1 threaded lead alloy type, compatible with M5 bolts, and the recommended tightening torque is 3.0±0.6 N·m (equivalent to 30.4±6.1 Kgf·cm or 26.4±5.3 Lbf·in).
Dimensions are 181.0±2.0mm long, 76.0±1.0mm wide, and 165.0±2.0mm high, with a weight of approximately 6.35kg (14.00 lb). The product meets the IEC 61056-1/2:2012 standard and is UL1989 certified (MH14533). Due to its maintenance-free design and high-efficiency gas recombination capability, it is suitable for renewable energy storage systems such as wind power generation and can maintain stable operation in harsh environments.
