GEL & AGM 12V deep cycle batteries
For most applications on vehicles and boats, Gel or AGM batteries offer best performance and life in the more demanding circumstances. Features include low self-discharge, high cyclic capacity, maintenance free and spill and leak proof.
AGM Batteries provide great performance for high current discharge applications. AGM Batteries are particularly suitable for use on high power inverters, bow thrusters, golf buggies etc. as their low internal resistance means less heat is generated within AGM Batteries, which would normally reduce the life of the battery.
Gel batteries deliver the best deep cycle durability and overall longer life. Gel batteries are particularly suitable for standby systems.
Flooded 2V - 4V - 6V - 12V Heavy duty traction batteries
Rolls high capacity flooded batteries provide high performance with economy. Rolls Batteries have been manufacturing batteries for more than 60 years and have built a reputation of reliability and long life. Rolls batteries have some of the longest warranties in the business at 10 years on some ranges! Rolls 4000 series and 5000 series batteries are suitable for off grid systems and marine applications where long life is required.
Gel 2V traction blocks
As the ultimate in lead-acid battery technology. These high capacity, long life 2V Gel battery cells, provide maintenance free service in high capacity heavy duty applications.
The latest developments in high capacity lithium-ion battery technology provide a viable alternative to traditional lead acid technology. WIth the ability to be totally discharged without damage over up to 1500+ cycles, stable voltage across full discharge and rapid recharge, significant power density and weight advantages are achieved. Whilst the initial expense of lithium ion batteries is significant, lifetime costs compare favorably with lead acid with significant advantages in space and weight saving.
