What is Electric Battery ?

The Frog Battery was used in early electrical research, it consists of dead or sometimes live frogs which form the cells of the battery.

All of these possibilities do, in fact, exist, and their various applications have produced the many different types of batteries available today (lithium, mercury, and so on). For years, however, the most common cell has been the 1.5 volt alkaline battery.

A high school student developed an average sized cell phone battery that can be fully charged in as little as 30 seconds.

The first known battery dates back 2000 years, could produce up to 2 volts, and its use was unknown.

Different batteries function better in different circumstances. The alkaline 1.5 volt cell is ideal for photographic equipment, handheld computers and calculators, toys, tape recorders, and other "high drain" uses; it is also good in low temperatures.

The benchmark used in PC battery life tests overstates true battery life by 50%. The productivity test involves running the office at lowest possible brightness with Wi-Fi off.

A high school student developed an average sized cell phone battery that can be fully charged in as little as 30 seconds.

This cell has a sloping discharge characteristic—it loses power gradually, rather than ceasing to produce electricity suddenly—and will lose perhaps four percent of its power per year if left unused on a shelf.

Keeping your laptop plugged in all the time will kill its battery faster.

Other types of batteries include a lithium/manganese dioxide battery, which has a flat discharge characteristic—it provides approximately the same amount of power at the beginning of its life as at the end—and can be used where there is a need for small, high-power batteries (smoke alarms, cameras, memory backups on computers, and so on).

Benjamin Franklin coined the term battery during his experiments with electricity.

Apple suggests 32° Fahrenheit as the lowest operating ambient temperature for the iPhone because a cold smartphone battery can drain faster than normal or it might say it has ample power remaining and then suddenly go dead.

Hearing aids, pagers, and some other types of medical equipment frequently use zinc air button type batteries, which provide a high energy density on continuous discharge. A mercury battery is frequently used in many of the same applications as the zinc air battery, because it, too, provides a steady output voltage.

This section, as well as the following section, will focus on alkaline batteries. In an alkaline battery, the cylinder that contains the cells is made of nickel-plated steel. It is lined with a separator that divides the cathode from the anode and is made of either layered paper or a porous synthetic material.

When charging a car battery, connecting positive to negative and negative to positive could result in damage to the alternator or even an explosion.

The canister is sealed at one end with an asphalt or epoxy sealant that underlies a steel plate, and at the other with a brass nail driven through the cylinder. This nail is welded to a metal end cap and passed through an exterior plastic seal. Inside the cylinder, the cathode consists of a mixture of manganese dioxide, graphite, and a potassium hydroxide solution; the anode comprises zinc powder and a potassium hydroxide electrolyte.
