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.

Battery Energy has been supplying proven and reliable battery storage systems on and off grid for 30 years.

Battery Energy’s Thick Plate Advanced Carbon Technology is industry leading and will continue to be installed in high temperature and cycling applications with Australias most innovative companies. When developing our technology in conjunction with the CSIRO there was a strong focus on delivering a product with superior cycling and life expectancies.

The result is a product with unique chemical and molecular characteristics which, along with advanced production methods differentiate it from other GEL batteries in the marketplace. These superior life characteristics apply to both the battery's cycling performance and its ability to combat varying extreme environmental conditions. For the highest level of reliability Battery Energy has the capability to design and customise products to meet increasing demands in the supply of energy storage for Solar, Communications, Rail, Oil & Gas, Power Generation & Transmission, UPS and Mining.
