NI-CD Pocket Plate Battery
Nickel Cadmium Pocket Plate Batteries are available in tough polypropylene containers of single cell types and block battery types. Cells of Stainless Steel containers or structural foam molded containers are also offered as options. Incorporating variations in electrode design to meet different current duration requirements. The batteries are classified into three types KPH (High discharge rate cells), KPM (Medium discharge rate cells) and KPL (Low discharge rate cell) . The performance of the batteries has been certified by the many independent international agencies. Sizes: 9AH to 1200AH
The Pocket Plate Nickel Cadmium batteries are the most advanced and proven technology currently available on the market today. They have a wide range of cell types available in traditional flooded cells in addition to recombinant styles. Battery racks and a host of accessories are available.
NI-CD Sintered Plate Battery
Nickel cadmium KPX (Ultra High Rate) batteries are specially designed using sintered positive plates and pasted negative plates for rugged diesel, genset, rail, and mobile applications.

FEATURES & BENEFITS
vs LEAD ACID FLOODED, GEL CELL, & VRLA BATTERIES)
NICD’s have the unique ability to withstand severe
environmental conditions. Many
of the installations are subject to varying temperatures of cold
(outdoor enclosures, substations, roofs) or heat (electrical equipment
rooms, boiler rooms, industrial plants, outdoor enclosures). Our continuous use temperature
ranges of - 40°C to +45°C (-40°F to +113°F) is important because most people
forget that Heat Kills Lead Batteries and that lead
warranties become void or have a very drastically reduced life when
over 77°F. An excellent realization comes when you and your customer
think about how much heat builds up in an outdoor, enclosed Genset or
Switchgear box which has the summer sun beating down on it.
The main problem in all applications is the risk of fire and
safety hazards if the circuit fails to trip, or if a Genset, Fire Pump,
or Emergency Lighting fails to start during an outage. With Switchgear, if the breaker
reset does not occur on a fault circuit, a building owner could also
face numerous complaints, and in the case of a utility it could also
effect their operating rating. NICD's offer
superior reliability against catastrophic failure.
performance: Amp hours (AH) are meaningless when facing high peak load
profiles. We offer
unmatched size, weight and life benefits when dealing with multiple
high current (peak) load profiles.
Unlike Lead batteries, NICD’s offer a high recharge efficiency
and can be left off charge for years, and then fully recharged without
any detrimental effect to their life or performance.
Cycle Life: NICD batteries typically can provide from significant Deep Discharge cycles to 80% of capacity.
Life: NICD batteries typically offer life expectancies of 15 to 25 years. They should not experience “Sudden Death” which is found in Lead Acid & Gel Cell Batteries.
Pricing: Includes flame arrestor vent caps, inter-cell connectors, and jumper cables for racks (if needed).
Battery pricing is for one set per system, and
includes inter-cell connectors, flame arrestor vent caps, and jumper
cables for racks, as required. Typical
battery sizing is based on the number of seconds of engine cranking,
engine cubic inch displacement, ambient temperature, engine oil
temperature and weight (viscosity), and parasitic loads, from a fully charged battery. All
Battery racks are of the modular stepped design, for total visibility
Cables from the battery to the system are not provided,
and must be sized to provide low resistance, (voltage loss), especially
if the batteries are not in close proximity to the equipment it is
If powering, multiple pieces of equipment, connect each directly
to the battery. Do
not connect to just one piece of equipment and then use a small jumper
cable between them.
NI-FE Nickel Iron Battery
Ni-Fe rechargeable battery not only has the most of characteristics of nickel cadmium pocket plate battery, but also owns the advantages of lower cost-in-use, minor self-discharge, long service life, low maintenance (more than 3 years), environmental-friendly, high mechanical strength, excellent resistance performance to electric abuse, good resistance to over-charge and over-discharge, therefore, Ni-Fe battery can replace Ni-Cad battery in many fields. After the Ni-Fe battery is charged according to standard charging system under the ambient temperature of 20˚C±5˚C, the battery can be normal used under the ambient temperature of -20˚C±60˚C (different discharge capacity under different temperature). This Nickel Iron battery is specially suitable for emergency lighting, solar photovoltaic applications and renewable energy storage applications under severe environment.
LiFePO4 Series & NCM Series
The Lithium-Ion cell manufactured by SCBC can be divided into two series, the one is IFP series with the anode material of lithium iron phosphate, as the other is ICP series with the anode material of lithium cobalt oxides. These lithium-ion cells have the following advantages: high operating voltage, high specific energy, small in size, light weight, long cycle life, low self-discharge, good discharge ability at high discharge rate, well adaptability at high-low temperature, high safety, no memory effect, environment friendly, etc. The products are widely used in the fields of UPS, mobile communication base station, energy storage, AGV, electrical bicycle, high-power start power supply, aircraft & aerospace, etc.
