• Good Floating Performance - 12V series VRLA deep cycle batteries are produced through internationally advanced technology and modern equipment and designed by fully type performance test. The positive plate uses high-tin alloy grids with strong corrosion resistance. The float charging life of battery can reach more than 5 years.
• Excellent Over-discharge Tolerance - Adopting dedicated ultra-fine glass fiber separators with high porosity and high wet-elasticity, combining with tight assembling technology, the battery has a high tolerance for super over-discharge. After 5 times of over-discharges which cause the short circuit, battery tolerance restoration can reach more than 95%.
• Super Cycling Ability - Special gel electrolyte additives, curing process at high temperature and high humidity are employed to delay the softening of active material, therefore the deep cycle endurance is improved up to 50%, especially the anti-passivation (anti barrier layer) capacity of positive plates during reaction when batteries are used for small load and small current discharge.
• Stable Consistency - Precise, quantitative, low temperature, vacuum acid filling method, advanced and environmentally friendly container formation technics ensures battery stable consistency.
• Large Current Discharge Performance - Small plate distance and high pressure tight assembly of plate group could enhance the ability of large current discharge performance.
• Safety and Reliability - Our patented terminal sealing construction and the curing process of the adhesive at high temperature, ensure no acid leakage from the roots of terminals, and therefore ensure safe and reliable operation.
• Maintenance-free - Due to dry-type design, gas produced from the battery internal system would all recombine and form into water. So the VRLA battery don't need filling water to achieve battery maintenance-free.
• Various Installation Types - The special AGM separators can absorb the electrolyte, thus there is no free acid inside the battery, and therefore both vertical and horizontal positions are allowed when the battery are to be mounted.
