Su-mak presents its range of high-performance Tall Tubular Batteries, specifically engineered for robust and reliable energy storage in demanding applications. Designed as "Very Low Maintenance" lead-acid batteries, they are an ideal power solution for solar energy systems, inverters, and other deep-cycle uses, promising a long service life and consistent performance.
This catalog details two models within the same form factor: the 200Ah and 220Ah capacities (rated at the C5 rate).
Long Cycle Life: Exceptional durability with a cyclic life of more than 1500 cycles at 80% Depth of Discharge (DOD) and more than 3000 cycles at 50% DOD, ensuring a long-term return on investment.
Very Low Maintenance: Engineered for minimal water topping-up requirements, reducing the need for frequent upkeep.
High Efficiency: Delivers superior performance with >95% Ampere Hour efficiency and >80% Watt Hour efficiency, maximizing the energy you put in and get out.
Excellent Charge Retention: Features a very low self-discharge rate of <3% over 28 days, meaning it holds its charge for longer periods of inactivity.
Robust Tubular Technology: The positive plates are tubular, cast using a high-pressure dye casting machine. This advanced construction is known for resisting shedding and corrosion, which is critical for deep discharge applications.
Fast Charging: Capable of accepting a high charging current (8-12% of rated capacity), allowing for quicker recharge times.
Premium Alloy Construction: Utilizes Antimony-Selenium (Sb/Se) alloys for both positive and negative plates, enhancing the battery's strength and performance over its lifespan.
The Su-mak Tall Tubular C5 Battery series is a reliable and efficient energy storage solution built for longevity and performance. Its robust construction, high cycle life, and low maintenance requirements make it a superior choice for off-grid solar systems, home inverters, and any application where deep, regular cycling is essential.
