2V 300AH Gel Deep Cycle VRLA Battery with 12 Years Life and Copper Terminal for UPS Systems

2V300AH High Capacity Gel Deep Cycle VRLA Battery, specially engineered for energy storage power systems. Featuring advanced design and formulation, this PV series is ideal for deep cycle applications such as solar power systems, providing extended power supply for small loads with low current requirements.

• Long Life: Utilizes high-tin alloy positive grids and thick plates to reduce active material utilization. With special additives, the designed battery life exceeds 12 years.
• High Cycling Ability: Special gel electrolyte additives, high-temperature curing process, and high-humidity conditions delay active material softening, effectively improving deep cycle endurance and anti-passivation capability.
• Excellent Over-discharge Tolerance: Features ultra-fine glass fiber separators with high porosity and wet elasticity, combined with high-pressure assembly technology. After 5 over-discharge cycles causing short circuits, battery capacity restoration exceeds 95%.
• Safety and Reliability: Patented terminal sealing construction and high-temperature adhesive curing ensure no acid leakage from terminal roots, guaranteeing safe and reliable operation.
• Various Installation Types: Special AGM separators absorb electrolyte, eliminating free acid inside the battery, allowing both vertical and horizontal mounting positions.

This series is suitable for energy storage in renewable energy systems including photovoltaic (PV), wind turbine power systems, and CATV applications.
