Key Advantages
- Long Life: VRLA gel type battery uses high-tin alloy positive grids and thick plates to reduce active material utilization. 40% DOD cycle life can reach over 3000 times as per IEC 60896-22-2004 requirements.
- Super Overdischarge Tolerance: After 5 over-discharges causing short circuits, battery capacity restoration reaches over 95%.
- High Cycling Ability: Special gel electrolyte additives and curing process delay active material softening, improving deep cycle endurance and anti-passivation capability.
- Excellent High-current Performance: Tight assembly design reduces plate distance, improving high current discharge performance.
- Safety: Corrosion-resistant rubber O-ring and special adhesive seal terminals, ensuring no acid leakage and reliable operation.
- Maintenance Free: Low liquid design recombines generated gases into water; no need to add water or acid.
- Various Installation Types: Special AGM separator absorbs electrolyte, allowing both vertical and horizontal mounting positions.
