Our professional grade batteries are deep-cycle batteries designed to store power from your small wind turbine or a hybrid solar-wind system. They are designed to be regularly discharged on a daily basis down to around 40% of their capacity. The sealed (VRLA) AGM lead acid batteries are ideal for off-grid power systems as they are maintenance-free and because they are also leak-proof the batteries are easily transported to a remote location.

We supply the Rolls Solar 5000 Series, Rolls AGM S Series, Rolls OPzV GEL Series and Platinum AGM batteries. Some deep-cycle batteries are also called 'leisure batteries' - we do not supply these as they are not designed for heavy use.
