The Su-mak Advance Tall Tubular C10 is a high-performance, very low-maintenance lead-acid battery engineered for durability and long service life. Designed explicitly for solar, inverter, and deep-cycle applications, it delivers reliable power with "Extra Backup, Extra Power, and Long Life." With a robust 200Ah capacity (at the C10 rate), this battery is built to handle frequent and deep discharges, making it an ideal energy storage solution for both home and commercial use.

Key Features & Benefits

1. Superior Longevity & Cycle Life:

   • Engineered for an extended lifespan, offering over 1500 cycles at 80% Depth of Discharge (DOD) and over 3000 cycles at 50% DOD, ensuring years of reliable service.

2. Advanced Tubular Plate Technology:

   • Equipped with 3 tubular positive plates per cell, manufactured using a high-pressure dye casting process. This advanced construction securely holds the active material, minimizing shedding and maximizing performance under repeated deep discharges.

3. High-Efficiency Antimony-Selenium Alloy:

   • Utilizes a premium High Antimony Selenium (Sb/Se) alloy (3.1% for positive, 2.5% for negative plates). This alloy enhances grid strength, improves deep discharge recovery, and reduces water consumption, contributing to its "very low maintenance" characteristic.

4. Excellent Energy Efficiency:

   • High Ampere Hour Efficiency (>95%) and Watt Hour Efficiency (>80%) ensure minimal energy loss during charge and discharge cycles, making it highly cost-effective and ideal for solar power systems where maximizing harvested energy is crucial.

5. Low Self-Discharge Rate:

   • Retains charge effectively with a self-discharge rate of less than 3% over 28 days, ensuring the battery is ready for use even after periods of inactivity.

6. Optimized for Solar & Deep Cycle Use:

   • Specifically designed to meet the demands of solar energy storage and deep discharge applications, providing consistent power and reliable backup.

7. Robust Build Quality:

   • Manufactured and tested in accordance with the BIS 13369:1992 standard, guaranteeing reliability, safety, and consistent performance.

8. High Power Delivery:

   • The tall tubular design and robust construction allow for high energy storage and reliable power delivery, ensuring "Extra Backup" as promised.
