The Cellyte CMT series of VRLA AGM single cells is the flagship large capacity design from SEC. Featuring heavy duty pure lead tin grids, the 20 year float life and excellent cycling make it the ultimate choice for high integrity large capacity installations.

The range also incorporates SEC’s industry leading CatVent catalyst technology as standard. This means lower float currents which in turn means reduced gassing, reduced cell heating and reduced positve plate corrosion. This gives you a product that has less cell dry-out, a reduced risk of thermal runaway, a reduction in the energy required for cooling and of course an extended life when compared to competitor products.

The 2V series is available in a wide range of capacities from 100 to 1600 Ah and with a choice of standard or V0 rated flame retardent tough ABS cases. A selection of bespoke racking solutions are also available ranging from economic tubular steels designs to premium modular specifications approved for Seismic Zone 4 installations.

The CMT range is manufactured in SEC’s ISO approved factories and is backed by a full 5 year warranty as standard.
