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

Industrial batteries translate chemical energy into electricity.

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. 

Battery chargers are devices for charging rechargeable batteries

Battery packs are constructed from two or more individual cells or batteries.

Battery holders are designed to support commercial, industrial or OEM batteries.

Disposable primary batteries are replaced once the energy supply is depleted. Their energy is produced when the materials within the battery react and are exhausted.

Industrial greases are thickened gels that consist of natural, synthetic, or semi-synthetic substances. They do not run off surfaces and are used in a variety of lubrication, sealing, and exclusion applications.

Metal rod and bar stock are metals and alloys in the form of round bars or rod, square bars, rectangular or flat bars, hexagons, and other bar stock shapes.

Industrial lubricants are oils, fluids, greases and other compounds designed to reduce friction, binding or wear and exclude moisture. Specialized characteristics may enhance thermal conduction across thermal interfaces or reduce electrical resistivity across electrical joints.

Atomic absorption spectrometers (AA) use the absorption of light to measure the concentration of gas-phase atoms

Spectrometers are analytical instruments which disperse an emission (such as particles or radiation) according to some property of the emission (such as mass or energy) in order to measure the amount of the dispersion. This product area includes visible, infrared (IR), ultraviolet (UV), atomic absorption (AA), optical emission (OE), Raman, X-ray fluorescence (XRF) and mass spectrometers. Specific search forms are also available

Electro-optic modulators are analog or digital devices that use an electric field to alter the characteristics (e.g., band gap and index of refraction) of a material through which light is traveling, changing the characteristics of the light itself.

Metal wire and strand has a round, flat, or shaped cross section. Products are usually less than 0.375" in diameter.

Electrical contacts and contact materials are soft, high-conductivity, oxidation- resistant materials that are used in circuit breakers, relays, switches, and electrical discharge machining (EDM) applications.  They often have a second phase in order to provide anti-welding and/or arc resistance.
