12V 250AH High Capacity VRLA Battery with Super Cycling Ability and 10 Years Design Life

12V250AH High Capacity Lead Acid Battery Valve Regulated Lead Acid Battery UPS Lead Acid Battery

By combining a newly developed corrosion resistance alloy and advanced curing process, we created a range of long life batteries - Duration range. The range features top termination and offers 10 years design life.

• Using oxygen recombination technology: maintenance-free
• Pb-Ca-Sn alloy for plate grids: less gassing and less self-discharging
• High quality AGM separator: extends cycle life and prevents micro short circuit
• ABS material: increases the strength of battery container (Flame-retardant ABS is optional)
• High purity raw material: ensures low self discharge rate
• Silver-coated copper terminals, brass insert terminals and lead terminals improve the electric conductivity

Cathode absorption sealed maintenance-free VRLA battery consists of ABS case, grid type plate, AGM separator and electrolyte.

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.

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%.

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.

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 could enhance 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, and therefore ensure 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, and therefore both vertical and horizontal positions are allowed when the battery are to be mounted.
