Photoconductive cells are light-sensitive resistors, in which resistance decreases with an increase in light intensity when illuminated

Battery and fuel cell test equipment consists of specialized test stations, stands or systems, monitors and component modules for performance or endurance testing. 

Load cells are transducers for force and load measurement, often with mounting packaging.  They are widely used in testing, instrumentation, and as components in larger devices such as scales

Lead, tin and low melting alloys (white metals) are non-ferrous alloys used in the manufacture of solder, semiconductor, battery and decorative products

Ball screws, lead screws, and ACME screws are used to convert rotary motion or torque into thrust or linear motion

Manufacturing cells and systems consist of a number of machines organized together to perform multiple operations on a workpiece

Photovoltaic cells generate a voltage when radiant energy falls on the boundary between dissimilar substances

Lead acid batteries are made up of plates, lead, and lead oxide with a 35% sulfuric acid and 65% water electrolyte solution

Fuel cells produce electricity and heat electrochemically by combining oxygen from the air with a fuel, preferably hydrogen, from methanol, natural gas, or petroleum. Reformers are often used in conjunction with fuel cells

Ceramic powders and precursors contain oxides, carbides, nitrides, carbon, and other non-metals. They are usually micron or mesh-size in distribution. Ceramic powders, sol-gel solutions and precursors are fabricated through atomization, crushing, milling, precipitation, and other chemical processes.

Rechargeable batteries or secondary batteries contain active materials that can be regenerated by charging. When the energy produced by rechargeable batteries drops below optimum efficiency, secondary batteries may be recharged in a couple of ways, depending upon their construction. 

Industrial batteries translate chemical energy into electricity.

Telephones and cell phones convert voice or other sound signals into a form that can be transmitted to another device that receives and reconverts the waves back into sound

Cell processors are multi-core processors that use cellular architecture for high performance distributed computing. They are made of hardware and software cells whose interoperability is similar to how neural cells perform in the human brain

Lithium batteries are primary batteries with a lithium anode.  They are disposable.
