Railway Battery Cells - Features & Benefits

Positive Plate
The tubular plate construction incorporates lead alloy spines in complete contact with active material, which is retained by a tube. This enables the electrolyte to penetrate freely, ensuring a high power output per unit volume.

Negative Plate
The negative plate is of a highly porous paste on an alloy grid. This complements the positive plate construction, providing a balanced performance and life.

Separators
Separators are manufactured from microporous polyethylene. They have a generous overlap to reduce the risk of short circuit and are
impervious to acid attack.

Containers and Lids
The cell container and lid are of polypropylene.
The lid is heat-sealed to the container ensuring a homogenous bond. This is vital to mechanical strength and safety.

All cells supplied by First National Battery are fitted with push in type vent plugs with "flip top" lids. Electrolyte level indicators are standard.

Max / Min Mark
Easily visible and simple to read.

Closed Cell Float
Ensures consistent accuracy over cell life.
