A tubular battery is a type of lead-acid battery that uses tubular positive plates, which enhances its durability and performance. This design makes them ideal for long-duration, high-power applications like home inverters and UPS systems in areas with long power cuts. Key benefits include a longer lifespan, superior deep discharge resistance, and lower maintenance compared to flat-plate batteries.
Design and components
Structure: Unlike flat-plate batteries, tubular batteries have a design where the positive plates are enclosed in tubes.
Positive plates: These are made of a lead-oxide-filled tubular structure, with the active material sealed in polyester tubes to prevent shedding and corrosion.
Negative plates: These are typically flat plates, positioned between the positive plates.
Key benefits
Longer lifespan: The robust design with tubes protects the active material, leading to a longer operational life, often from 4 to 6 years or more.
Deep discharge resistance: They are designed to handle deep discharges and recover efficiently, making them suitable for applications with frequent or long power outages.
Low maintenance: They require less frequent water top-ups compared to conventional flat-plate batteries.
High performance: They can deliver high peak power and are well-suited for heavy-duty usage and long backup times.
Thermal tolerance: They are better at handling extreme temperatures and managing heat, which improves performance and longevity.
Applications
Home inverters and Uninterruptible Power Supply (UPS) systems
Solar power systems
Other heavy-duty applications requiring long backup powe
