The first electrode design for Nickel Cadmium batteries employed the pocket plate construction which is still considered to be the most reliable design.

The formation of a vented pocket plate NiCd Battery

In Pocket Plate design, the active materials are encapsulated between folded steel strips which are perforated from both sides. This double perforation method increases the effective surface area by 30% and helps in better utilization of the active material thereby making the battery more efficient.

The batteries are manufactured in 3 series designated as H, M and L based on their performance capabilities. The H series have thin plates to provide for high discharge currents, the L series have thick plates to provide lower currents for long durations and the M series have an optimized plate thickness which is ideal for medium discharge performance and durations. These batteries are available as single cells of 1.2V or in blocks (individual cells thermally welded and connected either in series or in parallel) of higher voltages (2.4, 3.6V etc) and capacities.

Superior Technical Features:
The major advantages of NiCd battery is that it can tolerate deep discharges over long periods.
• Unsurpassed resistance to electrical and mechanical abuse.
