Advantages
- Good Floating Performance - Positive plate uses high-tin alloy grids with strong corrosion resistance. Float charging life can reach more than 5 years.
- Excellent Over-discharge Tolerance - Adopting dedicated ultra-fine glass fiber separators with high porosity and high wet-elasticity. After 5 times of over-discharges causing short circuit, battery tolerance restoration can reach more than 95%.
- Super Cycling Ability - Special gel electrolyte additives and curing process improve deep cycle endurance up to 50%, especially anti-passivation capacity during small load and small current discharge.
- Stable Consistency - Precise, quantitative, low temperature, vacuum acid filling method and environmentally friendly container formation technics ensure battery stable consistency.
- Large Current Discharge Performance - Small plate distance and high pressure tight assembly of plate group enhance large current discharge performance.
- Safety and Reliability - Patented terminal sealing construction and high-temperature curing process ensure no acid leakage from terminal roots.
- Maintenance-free - Dry-type design allows gas recombination into water, eliminating need for water filling.
- Various Installation Types - Special AGM separators absorb electrolyte, allowing both vertical and horizontal mounting positions.
