EXOR 2V OPzS battery series has achieved an extremely high level of cycling expectancy, which is using the tubular plates. OPzS battery features low maintenance, acid-proof and explosion-proof, which is an unexceptionable option for renewable power systems, like solar system, wind system and so on, the operation temperature range from minus 40℃ ( minus 40℉) to 65℃ ( 149℉). The model lasts a 15-year long designed floating life of 25℃ ( 77℉). EXOR 2V OPzS battery shows a preeminent performance after deep discharge, cycle times up to 8,000 cycles at 20%DOD, and 2,000 cycles at 80%. Each OPzS battery holds 2 electron volts, generally, one needs to combine more OPzS batteries together for a higher capacity of voltages.These models of OPzS Battery comply with the highest performance and reliability in a wide range of applications including Solar and Wind power system, UPS system, telecommunication and other applications of frequent deep cycles demands.
