The Nickel Cadmium Difference

In today's technological world, we all depend on electricity available on demand. When you require battery power or when you are suddenly deprived of your main power supply, that is when Alcad nickel cadmium batteries come into their own, as a completely reliable, self-contained source of power.

Alcad Technology

Alcad nickel cadmium batteries are designed to be absolutely reliable for 25 years and more. All that is necessary to achieve such longevity is simple maintenance. Outstanding reliability is just one feature of an Alcad nickel-cadmium battery. Other features are:

• Extremely long life - 25 years plus exceptional reliability.
• Wide range of operating temperatures:
  -40ºF +140ºF (-10ºC +60ºC).
• Good capacity at low temperatures.
• Excellent resistance to high-temperature aging.
• Resistant to electrical abuse (both over-charge and over-discharge).
• Excellent cycling capability.
• Accepts high rates of charge.
• Excellent shelf life in filled condition. Storage in any state of charge. Very good charge retention Very simple maintenance. No specific gravity checks.
• Excellent resistance to shock and vibration.
• Low installation costs. No special battery room required. Easy connection of cells.

Construction

The manufacture of Alcad nickel-cadmium batteries is a combination of electrochemistry and precision mechanical and electrical engineering. The heart of every cell is a series of steel pockets which are made from finely perforated steel strip filled with active materials - nickel in the positive plate and cadmium in the negative.

Product ranges are available In both plastic and stainless steel containers. Plastic container cells. details of which are given In this data sheet, offer a number of features such as translucency so that electrolyte levels are visible to aid maintenance. corrosion resistance in wet and saline conditions. and ease of assembly. Polypropylene. with Its high Impact resistance, is used for the majority of the Alcad cell ranges.

All Alcad plastic cased nickel-cadmium cells are fitted with flip-top flame arresting vents as standard, and are UL recognized.

Alcad products are manufactured within a Quality Management System officially recognized as meeting the requirements of ISO 9001. The approval is subject to regular monitoring by Bureau Veritas to ensure that standards in design and manufacture of nickel cadmium pocket plate cells and batteries are maintained.
