The maintenance-free Sigma 6V 260A (C100) gel battery is perfect for isolated solar installations of any size

The Sigma 6V 260A gel battery is a hermetic Lead Acid (VRLA) technology battery that offers an unbeatable combination of cycling performance, accompanied by a high cranking peak.

It is specially designed for isolated solar installations as well as other applications that require a long-term demand for electrical power supply. Gas Recombination Technology (VRLA) prevents water loss and eliminates the need for refilling.

Suitable for cyclical applications.

• It does not require maintenance.
• High resistance to deep discharges and repeated discharge cycles.
• Long useful life.
• Thanks to its gelled electrolyte, it can be used in a horizontal and vertical position.
• It can be transported safely, without fear of spills.
