Battery chargers are devices for charging rechargeable batteries.

Ultracapacitors store charges (energy) by physically separating positive and negative charges (unlike batteries which do so chemically).  Very high power densities can be achieved by this method

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

Industrial batteries translate chemical energy into electricity.

Capacitors are electronic components used for storing charge and energy. In their simplest form, capacitors consist of two conducting plates separated by an insulating material called the dielectric.

High voltage capacitors are used for storing charge and energy in high voltage applications. 

Electronic enclosures and instrument enclosures house electronic components and instruments. They are usually designed for handheld or desktop applications.

Gage blocks are manufactured to precise gagemaker tolerance grades for calibrating, checking, and setting fixed and comparative gages.

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.

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

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

Calibration standards and reference sources include any source that can provide a reference for the calibration of an instrument or comparison of a material or component.

Specialized or proprietary products and accessories related to batteries.

Radios are communication systems that send and/or receive electromagnetic waves. Devices such as citizens’ band (CB) radios, walkie-talkies, and handie-talkies are two-way radios that can be used for interpersonal communications.
