Cells and batteries are devices in which a spontaneous redox reaction produces electrical current.
It is not appropriate to know about the application of the various types of cells and batteries without first knowing the difference between these two devices. The basic generating unit is called the cell (stack). The voltage supplied by a cell may be insufficient to operate the equipment, so that two or more are associated in series, forming groups: the batteries.
Discover now the main cells and batteries together with their applications:
- common alkaline batteries: based on zinc/manganese elements. They are used to give life to toys, light to flashlights, sound to radios, autonomy to remote controls, among others.
- The calls special nickel-metal-hydride and lithium-ion batteries were produced especially for use in camcorders and notebooks.
- A special air zinc pile it is used to give hearing to the deaf, it makes the hearing aids work.
- At miniature button type batteries are those found in calculators, photographic equipment, watches, security systems and alarms.
Batteries when they are no longer used should be discarded, but not anywhere. According to CONAMA resolutions 257 and 263, you must return them to the manufacturer.
Mercury Oxide Battery: used in navigation instruments and measuring and control devices.
Nickel Cadmium Batteries: are rechargeables, we can find them on cell phones, cordless phones, radios, shavers, etc. They have the advantage of recharging, which prolongs their useful life.
