RYOTA Tubular Battery Overview

RYOTA tubular batteries are a type of lead-acid battery designed for durability and high performance, commonly used in deep-cycle applications such as renewable energy systems, inverters, and industrial equipment. Their unique design features tubular positive plates, which extend service life and improve efficiency compared to flat-plate lead-acid batteries.

Key Features

Tubular Positive Plates

• The positive plates are made with tubular sleeves filled with lead oxide active material.

• This design provides better structural integrity, reducing active material shedding and corrosion.

• The tubular structure allows deeper discharge and a longer cycle life.

Deep-Cycle Capability

• Ideal for deep-discharge applications, making them suitable for solar storage, inverters, and backup power systems.

• Capable of withstanding repeated charge/discharge cycles without significant degradation.

Long Service Life

• The robust structure of tubular plates ensures longer lifespan than flat-plate batteries.

• With proper maintenance, tubular batteries can last 5–10 years or even longer, depending on usage.

Low Maintenance

• Many tubular batteries are designed to be maintenance-free or require very minimal upkeep.

• Sealed designs or advanced electrolyte systems are often used to minimize water loss.

High Efficiency

• Tubular batteries have low internal resistance, improving charging efficiency and performance in deep-cycle applications.

Structure & Design

• Positive Plate: Tubular sleeves made of polyester or fiberglass filled with lead oxide.

• Negative Plate: Flat plates made from lead alloy.

• Electrolyte: Diluted sulfuric acid.

• Separator: Microporous separator to prevent short circuits.

• Container: Acid-resistant plastic casing.

Applications

Renewable Energy Systems

Widely used in solar and wind energy storage due to their deep-cycle capability and long lifespan.

Inverters

Commonly used in residential and commercial inverters to provide backup power during outages.

Industrial Equipment

Used in forklifts, traction equipment, and other heavy-duty machinery.

Telecommunications & UPS

Provide reliable backup power for telecom systems and Uninterruptible Power Supplies (UPS).

Advantages

• Long cycle life – ideal for deep-cycle applications.

• Durability – tubular plates resist corrosion and shedding.

• High efficiency – low internal resistance enables faster charging.

• Low maintenance – many models are maintenance-free or require minimal upkeep.

• Cost-effective – good balance of performance and cost compared to other battery types.

Disadvantages

• Weight – like all lead-acid batteries, tubular batteries are heavy.

• Initial cost – higher upfront cost than flat-plate batteries, but compensated by longer life.

• Charging time – must be properly charged to avoid sulfation and ensure long life.

Maintenance Tips

• Regular charging: Avoid deep discharge; charge promptly.

• Water topping: For flooded tubular batteries, check and add distilled water periodically.

• Terminal cleaning: Keep terminals clean to prevent corrosion.

• Proper ventilation: Ensure adequate airflow to prevent gas buildup.

Conclusion

RYOTA tubular batteries are a reliable and efficient choice for applications requiring deep cycling and long lifespan. Their robust design, low maintenance needs, and strong performance make them especially suitable for renewable energy systems, inverters, and industrial applications. Although heavier and more costly upfront than flat-plate batteries, their durability and efficiency make them a worthwhile investment.
