VRLA Electrolyte Storage Power 2V 500AH Gel Deep Cycle Battery
2V500AH Gel Deep Cycle Battery VRLA Gel Electrolyte Battery 2V Storage Power
Product Introduction
2V Series Gel Deep Cycle VRLA Battery is specially designed for storage power systems. Adopting particular design and formulation, this PV series is especially suitable for deep cycle applications like solar power systems featuring long time power supply for small loads with small current.
Product Features
- Long life: Uses high-tin alloy positive grids and thick plates to reduce utilization of active material. Designed battery life can reach more than 12 years.
- High cycling ability: Special gel electrolyte additives and curing process delay softening of active material, improving deep cycle endurance and anti-passivation capability.
- Excellent over-discharge tolerance: Dedicated ultra-fine glass fiber separators with high-pressure tighten assembly provide high tolerance for super overdischarge. After 5 over-discharges causing short circuit, capacity restoration reaches over 95%.
- Safety and Reliability: Patented terminal sealing construction and high-temperature adhesive curing ensure no acid leakage from terminal roots.
- Various installation types: Special AGM separators absorb electrolyte, allowing both vertical and horizontal mounting positions.
