Advantages
1. 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.
2. 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%.
3. 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.
4. Stable Consistency
Precise,quantitative,low temperature,vacuum acid filling method,advanced and environmentally friendly container formation technics ensures battery stable consistency.
5. Large Current Discharge Performance
Small plate distance and high pressure tight assembly of plate group could enhance the ability of
large current discharge performance.
6. Safety and Reliability
Our patented terminal sealing construction and the cuing process of the adhesive at high
temperature, ensure no acid leakage from the roots of terminals, and therefore ensure safe and
reliable operation.
7. 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.
8. 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.
