Regardless of whether you are an electrical engineer or not, you have probably seen a few distinct battery types. Batteries are frequently used in wall clocks, alarms, and smoke detectors, which utilize little disposable batteries, as well as in automobiles, trucks, and motorcycles, which use rather big rechargeable batteries.

In the past ten years or more, batteries have emerged as a major energy source. They played a significant role in our life even before that by powering a variety of portable devices including transistor radios, Walkmans, handheld games, cameras, etc.

Chemical energy is transformed into electrical energy by a battery to function. One end of the battery, or cell, becomes negatively charged while the other becomes positively charged as a result of a chemical process inside. The potential difference, or difference in charge, causes electrons to move throughout the circuit to which the battery is attached.

Types of batteries and their sizes

Without the restrictions of cords, plugs, and access to mains electricity, batteries let you continue working. Although the variety of batteries might occasionally be confusing, making the right option will help you to continue working effectively and efficiently. This article will discuss the fundamentals of battery operation, examine the various types of batteries that are available, and offer some advice on battery longevity, storage, and disposal. Well, in this article, I’ll be discussing the various types of batteries as the following questions will be discussed:

Contents

What are batteries?

A battery is a chemical device that stores electrical energy as chemical energy and transforms that chemical energy into direct current (DC) electric energy through an electrochemical reaction. The first battery was created in 1800 by an Italian physicist named Alessandro Volta. The electrochemical reaction in a battery involves the transport of electrons via an electric current from one substance to another (referred to as electrodes).

A Cell, as just mentioned, is the basic electrochemical unit that is the source of electrical energy created by the conversion of chemical energy, despite the fact that the term “battery” is frequently used to refer to the actual storage of energy.

What are the sizes of the batteries?

It is crucial to comprehend why different battery sizes affect how effective your equipment is overall. In general, a battery’s capacity to store energy increases with its size. Therefore, despite the fact that both big and small batteries are rated at 1.5V, the big battery has a larger energy reserve and a longer battery life. Because they transform chemical energy that has been stored into electrical energy, batteries are very helpful to us as consumers because they do away with the requirement for a direct power source.

The varying battery sizes depend on the device being used, both in terms of physical size and the amount of power needed. The size and shape of the particular item are taken into consideration while designing rechargeable batteries for consumer electronics products. Replaceable batteries typically have cylindrical shapes and are available in the sizes AAA, AA, C, and D.

AA Batteries

AA batteries, also referred to as “double A,” are by far the most widely used battery size. These batteries may be bought practically anywhere and are used in a wide range of applications. When people think of normal replaceable batteries, they typically visualize double A batteries.

These batteries are widely used in a variety of devices, including cordless phones, staffed pagers, and thermometers. AA batteries, which have a 1.5V voltage, are suitable for applications that need a somewhat high current flow but are not used constantly. They can also be applied to constantly-on yet energy-efficient devices like clocks.

AA Batteries

AAA Batteries

AAA batteries, also referred to as “triple A,” are the second most common type of battery. Small toys, thermometers, and calculators are all utilized with them. Small electronic devices like TV remote controls, kitchen timers, graphing calculators, and bathroom scales frequently use triple-A batteries.

Like AA batteries, AAA batteries have a 1.5V measurement, but because of their smaller size, they produce less power. Small, low-power gadgets like kitchen timers are the main applications for these batteries. The batteries will function well and last for a very long period. Additionally, thermometers and portion control scales are powered by these little batteries.

AAA Batteries

AAAA Batteries

Although “quadruple A,” or AAAA, batteries are less popular than their AA and AAA siblings, they nevertheless have a significant amount of power. These compact but potent batteries are frequently seen in laser pointers and LED penlights. Additionally, they are typically found in tiny gadgets like powered computer styluses, hearing aid remote controls, and glucose meters.

C Batteries

Toys, lamps, and portable radios are among the main uses for very powerful batteries. These 1.5V batteries are necessary for the use of many automatic hand sanitizer dispensers. You can be guaranteed that your gadget is running on safe, dependable power, making them ideal for demanding applications where batteries must be often used. Additionally, these batteries are widely utilized in restrooms with battery-operated flush sensors.

C Batteries

D Batteries

These batteries are best used in large flashlights, stereos, and hands-free soap or paper towel dispensers for devices that need an extended duration of power time. D batteries are required for most automatic paper towel dispensers to function. These big, hefty batteries can run a number of commercial, high-usage gadgets for hours at a time, including soap dispensers, air freshener systems, and hands-free sensor faucets.

D Batteries

9V Batteries

The 9-Volt battery, which is most frequently recognized for its rectangular shape, is employed in gadgets that need a lot of power and high voltage. Devices like infrared thermometers, temperature alarms with batteries, and electronic portion scales perform incredibly well with 9V batteries.

Extreme temperatures from food, walk-in coolers, or other kitchen appliances may all be encountered by these products. 9V batteries are incredibly strong and function brilliantly in temperatures ranging from 0 to 130 degrees Fahrenheit.

9V Batteries

CR123A Batteries

This battery is widely used for tactical equipment, wireless security, and home automation because it is so strong. The CR123A battery is substantially shorter than an AA battery but produces 3 volts, which is twice as much voltage as an AA battery.

These batteries are very powerful while still being rather compact. They guarantee peak performance and are perfect for high-power applications like LED torches. The high power-to-size ratio of this battery will let it live longer than others.

How do batteries work?

Chemical energy is transformed into electrical energy by a battery to function. One end of the battery, or cell, becomes negatively charged while the other becomes positively charged as a result of a chemical process inside. The potential difference, or difference in charge, causes electrons to move throughout the circuit to which the battery is attached.

A battery is made up of an electrolyte, which is either a liquid or dry powder that conducts electricity, and two separate conducting metals. A chemical reaction occurs when the battery’s two electrodes are coupled together in a circuit. Positive ions are drawn to the positive electrode while negative ions are drawn to the negative electrode (cathode). (anode).

This difference in charge causes the negative electrons in the circuit’s wires to be pushed around the circuit, transferring energy to its other parts.

The charge (potential difference) difference between the battery’s two ends is referred to as the battery’s voltage. More current is forced through the circuit at higher voltages, which results in a greater transfer of energy.

Since batteries are measured a bit differently than other electrical products, it’s vital to have some broad information about how batteries function before delving into the many chemical structures of different types of batteries.

A battery’s capacity is the quantity of charge it can store. It is expressed in milliamp-hours (mAh), also known as amp-hours. (aH). The mAh of a battery is typically listed on the battery’s side. Using this straightforward equation, you may estimate how long the battery will last:

Amp Hours (aH) / Amps (A) = Hours (H)

A gadget that consumes 250 mA of electricity, for instance, might be powered for 10 hours by a 2,500 mAh AA alkaline battery. However, the battery will last 100 hours if the load uses 25 mA of electricity. The overall life of your battery depends on what you use it for, however, as a general rule, a battery will hold its energy longer if its mAh is higher.

What are the types of batteries?

There are many factors to take into account while buying batteries. Depending on where the battery is being used, various chemical structures offer distinct advantages. The most typical battery types and their advantages and disadvantages are shown below.

Alkaline, Nickel Metal Hydride (NiMH), and Lithium Ion are the three types of batteries that are most frequently used. These batteries have unique features due to the use of various metals and electrolytes, making them appropriate for usage in a variety of settings.

Lithium Batteries

Rechargeable lithium-ion batteries are a more recent innovation and are increasingly employed in laptops and cell phones. The number of recharging options makes them more expensive than NiMH at the time of purchase, but they will end up being less expensive in the long run. The ease of charging and more reliable power delivery throughout the course of its lifetime are further factors in lithium batteries’ desirability.

Just as earlier mentioned, one of the most widely used battery types is lithium. They have the highest energy density of any battery cell, which equates to more energy storage capacity than other batteries like alkaline. Despite only being offered in AA, AAA, and 9V capacities, lithium batteries have higher mAh ratings than any other non-rechargeable battery. One AA lithium battery has a capacity of 2,700–3,400 mAh and has a long lifespan, even when used often.

Carbon Zinc Batteries

When zinc (Zn) and manganese dioxide (MnO2) interact electrochemically in the presence of an ammonium chloride (NH4Cl) electrolyte, a zinc-carbon battery produces a direct electric current. The zinc anode, which is typically built as a cylindrical battery cell container, and a carbon rod surrounded by a substance with a higher Standard electrode potential (positive polarity), known as the cathode, that gathers the current from the manganese dioxide electrode, produce a voltage of about 1.5 volts.

Although very cheap, carbon zinc batteries have a very poor energy density. Frequently, these batteries won’t be able to give a high-drain product more than enough power to turn it on.

Carbon Zinc Batteries

Advantages

Disadvantages

Silver Oxide Batteries

A primary cell that uses zinc for the anode and silver oxide as the cathode is known as a silver oxide battery. During discharge, these cells keep their nominal voltage practically constant until they are completely depleted. They are offered in tiny sizes as button cells, where the amount of silver utilized is negligibly small and does not contribute significantly to the cost of the final product.

Watches and other tiny devices frequently employ silver oxide batteries. Since the battery is made of genuine silver, it is frequently only offered in button cells, where the silver content has no impact on the final product’s price.
