Product details
The CSB XHT8000FT belongs to the XHT series of 12V front terminal valve-regulated lead-acid batteries, featuring AGM absorbed glass mat separators and a dedicated grid design, with a 99% gas recombination rate, and employing pure lead construction and Catalist 2X proprietary additive technology. The product is maintenance-free, with a case made of impact-resistant PC-ABS flame-retardant material meeting UL 94-V0 requirements, suitable for high-rate and high-temperature standby scenarios, and intended for mission-critical power supply in demanding environments.
In terms of electrical parameters, the battery has a nominal voltage of 12 Vdc and a nominal capacity of 8000W @ 5min-rate (9.60V per PCS @ 25°C). Watts per cell data are 1831.17 W/cell at 30 seconds at 1.67 VPC, 1287.17 W/cell at 5 minutes at 1.67 VPC, and 821.50 W/cell at 15 minutes at 1.67 VPC. Maximum charge current is 66.70 A, maximum discharge current is 1660 (5sec), short-circuit current is 4570 A, and internal resistance is 2.17 mΩ. Float charge voltage is 13.5 - 13.8 Vdc/battery (25°C), and equalizing charge voltage is 14.4 - 15.0 Vdc/battery (25°C).
In terms of structure and dimensions, the XHT8000FT is 558.0±2.5 mm long, 126.0±1.5 mm wide, and 325.0±2.5 mm high, weighing 66.6 kg. The terminal is an I2 thread lead alloy terminal to accept M6 bolt, with terminal torque of 51.7±10.3 Kgf∙cm, 44.9±9.0 Lbf∙in, or 5.1±1.0 N∙m. Design life reaches 12+ years at 25°C float service and 10 years at 35°C float service. Operating temperature range is -40°C to 65°C for discharge, and -40°C to 65°C for both charge and storage.
Regarding self-discharge, self-discharge is less than 10% after 90 days at 25°C, storage is possible for up to 6 months, extendable to 10 months with equalizing charge; a full charge is required before use, and if storage temperature exceeds 25°C, recharge should be performed sooner. The product is manufactured in accordance with IEC 60896-21/22:2004 and UL1989 (MH14533), and is UL 1973 Recognized (MH66728).
