Gel and AGM 12V deep cycle blocks
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 whilst Gel deliver the best cyclic life.
Gel and AGM 2V traction blocks
As the ultimate in lead-acid battery technology, these high capacity, long life cells provide unmatched, maintenance free service in high capacity heavy duty applications.
Vented 2V traction duty cells
Our high capacity vented battery products provide high performance with economy. Ideal for stationary applications (i.e. off grid and other land based use) they can also be used in some marine or vehicle environments where movement and mechanical shock are less severe; Narrowboats and broad-beam barges are typical examples.
Lithium-Ion
The latest developments in high capacity lithium-ion 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 is significant, lifetime costs compare favorably with lead acid with significant advantages in space and weight saving.
