12V 200AH VRLA Battery - Maintenance-Free Valve Regulated Lead Acid Battery with ABS Material

12V series VRLA deep cycle batteries are produced through internationally advanced technology and modern equipment. The positive plate uses high-tin alloy grids with strong corrosion resistance. The float charging life of battery can reach more than 5 years.

Adopting dedicated ultra-fine glass fiber separators with high porosity and high wet-elasticity, combined with tight assembling technology, the battery has a high tolerance for super over-discharge. After 5 times of over-discharges which cause short circuit, battery tolerance restoration can reach more than 95%.

Special gel electrolyte additives, curing process at high temperature and high humidity are employed to delay the softening of active material, improving deep cycle endurance up to 50%, especially the anti-passivation capacity of positive plates during reaction when batteries are used for small load and small current discharge.

Precise, quantitative, low temperature, vacuum acid filling method, advanced and environmentally friendly container formation technics ensures battery stable consistency.

Small plate distance and high pressure tight assembly of plate group enhances the ability of large current discharge performance.

Our patented terminal sealing construction and the curing process of the adhesive at high temperature ensure no acid leakage from the roots of terminals, ensuring safe and reliable operation.

Due to dry-type design, gas produced from the battery internal system would all recombine and form into water. So the VRLA battery doesn't need filling water to achieve battery maintenance-free.

The special AGM separators can absorb the electrolyte, thus there is no free acid inside the battery, allowing both vertical and horizontal positions when the battery is to be mounted.
