Super Jumbo Tubular vs Tall Tubular Batteries: Which is Better?

When power backup becomes essential, selecting the right inverter battery plays a crucial role in ensuring uninterrupted performance. Okaya offers two advanced energy storage solutions—Super Jumbo Tubular (SJT) and Tall Tubular (TT) batteries—each engineered to deliver long-lasting support, consistent output, and ease of maintenance across a wide range of applications.

This blog highlights the strengths of both formats—not to compare, but to inform. Okaya manufactures both SJT and TT batteries with the same high standards, offering reliable performance tailored to meet specific installation and backup needs.

What is a Super Jumbo Tubular Battery?

The Super Jumbo Tubular (SJT) battery is an evolved, compact design that integrates the structural benefits of Okaya’s Tall Tubular technology. With a layout optimized for space efficiency and maintenance convenience, SJT batteries are built to deliver consistent backup for homes and businesses alike.

Key Strengths of SJT Batteries:

Compact Footprint: Space-saving dimensions (540 x 210 x 317 mm) make it suitable for modern home interiors and space-limited installations.

A. 6x1 Water Topping Layout: Designed with all water inlets on one side for safe, quick, and clean maintenance.

B. Taller Tubular Plate Design: Offers high recharge efficiency and prolonged backup duration by leveraging vertical plate engineering.

C. Faster Recharge Time: Reduces downtime between charging cycles, ensuring faster readiness.

D. Certified Backup Hour (CBH): Performance tested under controlled conditions to ensure consistent output matching the application load.

E. Ultra-Low Maintenance: Low antimony alloy construction minimizes water loss, reducing the frequency of service intervals.

F. Spill-Free Water Topping: Innovative float plug system allows clean and easy water refilling without plug removal.

These features make the SJT battery a compact and efficient solution, especially for those seeking high performance in modern installations with restricted space.

What is a Tall Tubular Battery?

Tall Tubular (TT) batteries are known for their high backup capacity, long service life, and adaptability to a wide range of energy demands. Okaya’s TT batteries are engineered with Advanced Tubular Technology and deeper plate design to deliver enduring power for both residential and commercial environments.

Key Strengths of TT Batteries:

A. Long Backup Support: Tall plate construction allows deeper discharge cycles, making it suitable for long-duration outages.

B. Advanced Tubular Technology (ATT): Enhances battery life and provides stable output across continuous charging and discharging.

C. Xtra Backup Design (XBD): Delivers additional reserve capacity, increasing backup time as per application needs.

D. Spill-Free Float Plug System: Simplifies the water topping process and helps regulate vapor and pressure, reducing spillage.

E. Heavy-Duty Terminal Design: Embedded terminals protect against corrosion and mechanical stress, improving long-term reliability.

F. Low Self-Discharge Rate: Maintains charge efficiently during idle periods, ensuring backup is available when needed.

With proven performance across homes, shops, telecom towers, petrol stations, and healthcare setups, TT batteries are a dependable energy storage solution for environments with consistent power needs.

Trusted Performance in Both Formats

Both SJT and TT batteries share Okaya’s signature engineering benchmarks. Each model is built with:

A. Advanced Tubular Technology (ATT) for longer service life

B. Xtra Backup Design (XBD) for extended runtime

C. Certified Backup Hour (CBH) ratings for reliability and transparency

D. Spill-free and low-maintenance construction for user convenience

E. Durable terminals and wide operating range to perform under real-world conditions

Rather than being compared, these batteries complement different installation needs and application scales, while maintaining the same trusted Okaya standards.

Certified Backup Hour (CBH): Test Conditions & Clarification

To support clarity in performance expectations, Okaya uses Certified Backup Hour (CBH) testing under controlled industry protocols. This helps align product capabilities with the actual power backup needs of homes and businesses.

CBH Test Conditions:

Constant current charging until terminal output reaches ≥15.5V

Specific Gravity: 1.25–1.26

Cutoff Voltage at end of discharge: 10.5V

Open Circuit Voltage (OCV): 12.50–12.70V

Test Temperature: 27±2°C
