Batteries in their definition are electrochemical devices that convert chemical energy into electrical energy. Their composition is based on a set of electrolytic cells used to supply a supply of direct or direct electric current. There are primary cells and secondary cells. Primary cells colloquially called batteries produce electricity in an irreversible chemical process, so they must be discarded and replaced. Secondary cells or accumulators act according to a reversible principle, and it is possible to recharge them by being in contact with another suitable source of electrical current to provide charging.
All cells have two electrodes immersed in an electrolyte. The electrolyte is a substance, often liquid, which serves as an electricity conductor thanks to its dissociation into a high number of ions. These are atoms that have lost or gained electrons, and therefore have an electric charge.
The nine-volt battery has a common size and was used in transistor radios. The 9-volt battery has a rectangular shape with rounded edges and a polarized pressure connector on top of it. This type of battery is frequently used in walkie-talkies, clocks and smoke detectors. This battery is useful for powering electronic devices, toys, or electronics projects. It is long-lasting alkaline, with a rated capacity of 150 mAh and is free of cadmium and mercury.
Cutting-edge technology designed specifically for today’s most power-hungry high-tech devices, such as digital cameras, PDAs, handheld games and portable audio equipment. It can be charged hundreds of times and held for up to six months.
These Rechargeable Batteries are:
This type of batteries can be found in any market and can be simple or rechargeable, you can also find in your favorite brands such as: Duracell, Energizer, Odec, among other brands.
The maximum current depends on the type of battery, in general for an alkaline, the maximum current does not exceed the Ampere. For Nickel-Metal batteries do not exceed 2.5 amperes.
Below that, if ohm’s law is to be applied: I = V/R
What may also interest you is the capacity, measured in mAh, which also depends on the material with which it is manufactured, and the consumption demanded of it. For example, an alkaline battery that makes you work constantly with 25mA has a capacity of 600mAh, while working at 500mA has a capacity of 250mA.
