The new Changhong gas composite battery is developed by integrating the mature bag-type battery technology and Changhong's new technologies. With its ultra-low maintenance or even maintenance-free characteristics, it has become an ideal choice for new backup power supplies.

Technical Advantages:

• The plates are all supported by steel strips as the skeleton, which do not react with the electrolyte and remain intact throughout their service life.
• The separators are made of a new type of polypropylene fiber felt material.
• No electrolyte replacement is required during the battery's service life.
• The terminals are processed from steel or copper materials with excellent conductivity and high mechanical strength.
• The battery case is made of high-strength, corrosion-resistant, semi-transparent engineering plastics.
• No "sudden death" phenomenon occurs.
• The composite efficiency of the battery can reach 85% - 95%.
• The extremely high gas composite efficiency can reduce water consumption by 90%.

Long Service Life and Low Maintenance

• During the battery's service life, the electrolyte needs to be added at most once.
• The cycle life is more than 2,000 times, and the reasonable service life can reach more than 25 years.
