Designed for all standby duties, including power stations, telephone exchanges, switchgear operation, telecommunications, emergency lighting and diesel starting. Noteworthy advantages of these cells are:

	Ease of inspection, testing and maintenance (a hydrometer reading indicates the state of charge).
	Lower internal resistance which provides increased performance at high rates of discharge.
	No falling-off of capacity with age.
	Life expectancy of 20 years or longer.
	Designed for float-charge operation, always ready for use.
				Cells comply with SABS IEC 60896-1:1987 and conform to SABS ISO 9001 Quality Management System.

DESIGN FEATURES:

POSITIVE PLATES are 8mm thick pure lead grids for longer life and to provide sufficient material to ensure that there is no fall-off of capacity throughout the life of the cell.

NEGATIVE PLATES are of industrial pasted grid construction, for balanced performance and life.

SEPARATORS, of Porvic 2 (sintered microporous PVC), form a complete diaphragm between the plates. The separators are chemically inert with a high degree of porosity, which ensures minimum internal resistance.

VISUAL INSPECTION CONTAINERS, moulded from transparent styrene acrylonitrile (SAN) to provide optimum transparency and very high insulating qualities, eliminating the need for separate cell insulators.

CELL LIDS are moulded from opaque SAN permanently sealed to the container.

VENT PLUGS are of a special design which effectively returns all acid spray to the cell, but allows free exit of oxygen and hydrogen gases.
