35% longer cycle life

SunGEL® Ultra is the successful development of Battery Energy’s proven Australian designed SunGEL batteries.
The robust Thick Plate design combined with the introduction of innovative Advanced Lead Carbon-Micro Catalyst technology, reduces sulphation, improves cycling and assists recharge. Designed to perform, these batteries have an industry leading cycle life under recommended operating settings and will provide reliable energy for many years of service.

Designed for safety

Protection was paramount when developing the SunGEL products. With ABS fire retardant containers as standard as well as fire arrestor vents, this battery exceeds all necessary safety standards.

Proven resilience in high temperature

SunGEL Ultra batteries are designed to endure higher average temperatures. The Advanced Carbon-Catalyst Technology creates optimum charge efficiency and prolongs their life in high temperature applications up to 35°C without the need of compensation.

Maintenance-free 20-year design life

With superior deep-cycle performance, SunGEL Ultra batteries are manufactured with proprietary gelled electrolyte to prevent drying out. This allows your batteries to operate for long periods maintenance-free – even in extreme climates.
