SunGEL Ultra Batteries

A safe and superior storage system with a life expectancy to meet the demands of heavy cycling for both on and off-grid solar applications.

Australian designed Lead Carbon-Catalyst technology

Introducing SunGEL Ultra. Now with 30% longer cycle life, the newest generation of SunGEL batteries have an industry leading cycle life at 5,950 cycles under recommended operation and settings. The robust Thick Plate design with Advanced Lead Carbon-Catalyst technology to give you a battery with a premium 20-year design life.

For over 30 years, Battery Energy has delivered a proven and reliable battery. Through ongoing development, we continue to ensure the SunGEL range remains the best choice for solar applications.

30% longer cycle life

Positive grid corrosion and negative plate sulphation are the main causes of failure in a battery. With this in mind, we designed our batteries with Advanced Carbons to reduce sulphation, improve cycling and assist recharge. SunGEL Ultra batteries also features Micro Catalysts to decrease required charging float currents.

These features plus the Ultra Thick positive plate minimise corrosion making sure your batteries last for thousands of cycles and provide reliable energy for many years of service.

Proven resilience in high temperature

Along with superior deep-cycle and float performance, SunGEL Ultra batteries are manufactured with Advanced Carbon-Catalyst Technology for optimum efficiency allowing them to charge more efficiently and prolonging their life in high temperature applications. Without the need for external cooling to compensate, these batteries will perform supremely in temperatures up to 35°C before cooling is required.

Their gelled electrolyte prevents drying out, unlike other technologies, and allows your battery to operate for long periods maintenance free in extreme climates.

Flexible block sizes

Our SunGEL Ultra range comes in 2V, 4V, 6V and 12V blocks giving you greater flexibility when designing a new system or connecting to an existing system.
