The round tube has the following advantages over the conventional square tube: it offer a more uniform active material dstribution around the supporting spines, resulting in more efficent utilisation of materials it is less prone to distortion under operationg conditions it offers a greater surface area for a specific plate dimension, affording higher energy density it has a small footpring.

POSITIVE PLATE
The tubular gaunlet plate construcion consists of special lead alloy spines in complete contact with superior active material , effectively retained by woven terylene tubes. The terylene gauntlets, which are resins impregnated, combine high tensile strength with resilience, retaining the active material while enabling the electrolyte to penetrate freely. This ensures a high power output per unit volume.

NEGATIVE PLATE
The negative plate is of a special alloy grid containing a highly-porous paste formulation, giving a balanced performance and life, and complementing the positive plate construction.

CONTAINER
Moulded, DIN standard, transparent styrene acrylonitrile, giving very high insulating properties which eliminate the use of insulators. Age or acid contact will not cause deterioration.

LIDS
Moulded from opaque styrene acrylonitrile

VENT PLUGS
The special design affectively returns all acids spray to the cell, yet permits free exit of oxygen the hydrogen.

END BUFFERS
PVC end buffers provide additional lateral support at each end of the emenet, ensuring a compact assembly to prevent the plates splaying.

SEPARATORS
High quality, microporous rubber separators. Chemically-inert, with a high degree of porosity , they offer minimum internal resistance. These wraparound separators preventshort-circuiting caused by mossing.
