HBL's Nickel Cadmium Pocket Plate Battery designs are based on the superior Pocket Plate technology.

The first electrode design for Nickel Cadmium Batteries employed the pocket plate construction which is still considered to be the most reliable design.The fully integrated modern factory, supported by strong process management and quality controls makes HBL one of the best Nickel Cadmium Battery production facilities in the world.In HBL’s 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.

Nickel Cadmium Fibre electrode batteries may be seen as 3rd generation (1980’s) technology. Pocket plate is 1st generation (1919's) and Sintered Plate is 2nd generation (1950’s). The Fibre Electrode Technology has been provided by DAUG, Germany (research venture of Mercedes Benz & Volkswagen).

The Nickel Fibre matrix used for the fibre plate allows 90% of the electrode volume for holding the active material. The open three dimensional fibre structure also provides good conductivity to ensure excellent electrical performance.

Nickel Cadmium Fibre plate technology uses active material free from graphite and iron. Elimination of these elements ensures that the electrolyte does not get carbonated and reduces water consumption.

The elastic nature of NCFP electrode enables it to absorb greater shock and vibration stresses. This includes volume changes during charge and discharge cycles, hence the battery can give more number of cycles compared to other battery technologies. The NCFP technology is considerably lighter in weight and hence has high energy density.

Fibre Plate batteries are manufactured in 4 series (X, H, M and L) based on their performance capabilities. The X series have very thin plates for ultra high rate discharge performance. The H series have thin plates for excellent high rate discharge performance. The L series have thick plates to provide long duration, low current discharge performance. The M series have an optimized plate thickness which is ideal for medium discharge performance and durations.

The wide range of Nickel Cadmium Fibre Plate batteries are available in tough, fusion-welded polypropylene cell containers and lids. When placed on multi-step battery racks, the electrolyte level in all the cells can be visually monitored to facilitate maintenance. For special requirements, the containers can be offered in flame-retardant polypropylene, structural foam-moulded polypropylene or stainless steel.

The batteries are supplied with all related hardware and racks are offered as an option.

Sintered Positive and Pasted Negative batteries

Nickel cadmium KRM, KRX and KRH batteries are specially designed using sintered positive plates and pasted negative plates for rail applications.

The sintered positive plates are manufactured using a high-temperature sintering process to form strong plates, which can survive the rigors of rail applications. The pasted negative plates are specially designed with high power density and have reduced water consumption. The sintered micro-porous separators and membrane separators provide insulation between the plates and permits free flow of ions.

These batteries use polypropylene cell containers with thermally welded lids for high impact resistance. Flame retardant containers and lids are optional. Steel or copper terminals and fasteners give these batteries the ruggedness required to meet the demanding application needs. Single cells are provided with reliable flame-arresting vents and are assembled in stainless steel crates for easy handling. Block batteries are provided with integrated water filling system.

The NCSP technology is considerably lighter in weight and hence has high energy density. 

Sintered Plate batteries are manufactured in 3 series (KRM, KRX and KRH) based on their performance capabilities and application.

KRM Nickel cadmium single cell batteries are designed to provide fail-safe emergency back-up power for lighting, air-conditioning, radio communication, door control, computing and other applications requiring medium power.

KRX Nickel cadmium single cell batteries are designed for diesel engine starting, emergency braking and other applications requiring high power for short durations. KRX has exceptionally good performance even at very low temperatures and starting is guaranteed even at temperatures as low as -20°C.

KRH Nickel cadmium Block batteries are designed for fitment in space constrained locations and are more suited for installations featuring an integral tray as in Light rail vehicles, metros, electric multiple unit (EMU), electric locomotives and high speed rail systems.

Electrolyte level in all the single cells can be visually monitored to facilitate maintenance. For special requirements, the containers can be offered in flame-retardant polypropylene, structural foam-molded polypropylene.

Superior Features:

    • Optimized performance to suit application requirements (specific design for each application).
    • Fits in a very small space (saves 20% to 60% of space used over conventional lead acid batteries).
    • Lighter than conventional lead acid batteries (reduction in 20% to 50% of the weight of conventional lead acid batteries).
    • Performs even at extremely low temperatures (less than -20°C).

VRPP: Nickel Cadmium Valve Regulated Pocket Plate Batteries 

The Valve Regulated Pocket Plate (VRPP) battery combines the unmatched reliability of Nickel Cadmium pocket plate technology, with the convenience of ultra-low maintenance requirements.

VRPP’s controlled recombination system, with valve regulated venting means no water replenishment is needed during its lifetime under recommended operating conditions. VRPP performs in severe environments, in temperatures ranging from -20° C to +40° C and can survive over-discharge, reversal or prolonged overcharge with no damage.

The Pocket Plate design consists of the active materials 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. In addition to the Pocket Plate design, the VRPP batteries use a special separator which allows gases generated during charging to recombine inside the cell thus ensuring no water is lost. This makes the VRPP battery virtually maintenance-free. A self resealing type vent cap is also employed to release any excess pressure developed inside the cell during abnormal operation.

The batteries are available in tough, fusion-welded polypropylene cell containers and lids. For special requirements, the containers can be offered in flame-retardant polypropylene.

HBL's batteries are supplied with electrolyte, inter-cell connectors and related hardware and accessories required for normal operation and maintenance. Suitable battery racks are also offered as options
