10 Types of Batteries and their Uses(Pros & Cons)

Portable devices have become a vital part of our lives as they offer us the convenience of being able to take them with us wherever we go. Batteries power all these devices, making them completely portable. The type of battery used depends on the device and application. For example, a laptop would require a different type of battery(shape and size) than a smartphone.

How many types of electric batteries are there?

Batteries are broadly classified into primary batteries and secondary batteries. The primary batteries are for one-time use only as they cannot be recharged. Whereas, the secondary batteries are rechargeable. Both types are further classified into different batteries.

Both types are further classified into different batteries depending on the chemicals used in them. For example, a lead-acid battery used in vehicles is a secondary battery, and the zinc-carbon batteries used in flashlights are primary batteries. There are also lithium-ion batteries, which are a type of rechargeable or secondary battery.

Different battery types have different advantages and disadvantages. For example, lead-acid batteries are very durable but require regular maintenance, while lithium-ion batteries have a high energy density but are more expensive. Ultimately, the type of battery that is best for a particular application depends on a number of factors, including cost, weight, size, and required shelf life. Given below is the list of the types of batteries that are most commonly used.

What are Primary Batteries?

A primary battery is a type of battery that cannot be recharged and must be discarded once its power is depleted. The most common type of primary battery is the disposable dry cell, which is used in a wide variety of applications, from flashlights to watches.

Primary batteries are convenient because they are ready to use out of the box, but their limited lifespan can be costly in the long run. It is non-rechargeable because the chemical reactions that happened in it are irreversible and the chemicals cannot return to their original form.

The key advantages of primary batteries are they are cheap, lightweight, easily available, have less maintenance, and come in several configurations. They are usually used in devices with low current drain.

The major disadvantage of primary batteries is that they cannot be reused. Also, these batteries have comparatively less capacity.

Still, primary batteries are very commonly used around us. The best example is remote controls and other lightweight portable devices.
