It is common to see battery-operated portable electronics on a daily basis, including cell phones, watches, remote control, electric bikes, key fobs, and so on.

Batteries have become such an indispensable power source that we can hardly imagine what our life would turn out to be without the presence of these tiny cells.

While cells are a small particle, delivering DC voltage and current to empower small electronic devices like remote controls, a battery pack comprises numerous sections, producing large amounts of electricity desired.

There is a wide range of various battery types on the market, meeting the customers’ energy demand for their gadgets.

While you can come across such batteries as coin cell, button cell, or cell of different battery sizes, there are two main types of batteries: rechargeable batteries and non-rechargeable batteries.

So what are they and their practical applications? How to choose a suitable battery for your device? Keep reading our article to find out the answers!


All Should Know About Batteries

As mentioned above, batteries are produced to empower various portable electronics, and they are made of numerous cells.

Under the chemical reaction, those cells immediately create an electron flow within a circuit, then an electric current appears.

A battery cell usually comprises three main components: a negative electrode, a positive electrode, and the electrolytes.

The movement and impacts of those three components on each other create the little source of energy that we and several types of machines are thankful for.

Main components of batteries and their operation

In general, a battery is made up of three main bits: two electrodes and one chemical called an electrolyte.

With a view to ensuring our safety, all three components are stored inside a metal outer case.

Besides, a battery is designed with two outer electrical terminals: positive and negative.

These two terminals are where you transmit the electrical current into the three inside bits to generate the needed power.

When there is a current running through the battery, a chemical reaction is likely to happen with the ion formation from the materials in the electrodes.

Meanwhile, the electrons from one terminal start to move to the other side through the outer circuit.

This process only stops with the total transformation of electrolyte and the appearance of the needed power.

Battery types



In general, batteries are classified into two aforementioned main types, rechargeable and non-rechargeable batteries.

The primary batteries or non-rechargeable ones cannot be reused when they are depleted.

Alkaline batteries and coin cell or lithium batteries are the most common non-rechargeable batteries in our daily lives, having a long shelf life and a small size.

We can use them for our key fob or hearing aids.

On the contrary, the second batteries can be reused and recycled by a battery charger, ensuring users a huge life span.

This type of battery includes four common types, namely lead-acid batteries, Ni-Cd batteries, Ni-MH batteries, and Lithium-ion batteries.

As it can be recharged and reused like renewable energy, this type of battery often powers electric vehicles like electric bikes, golf carts, electric cars, personal watercraft, and other devices like baby monitors, digital cameras, or emergency light.

Although it comes at an expensive price, the rechargeable battery ensures the user’s long-term use and high efficiency.

How To Choose A Suitable Battery

A battery may directly impact your devices’ operation, but determines the gadget’s longevity.

So when facing a wide range of batteries available on the market, how can you choose a suitable one for your devices?

Here are some factors that you need to consider when buying batteries:

  • Choose between chargeable and non-rechargeable batteries

First and foremost, let’s have a second thought about your purposes when buying batteries.

If you are longing for a portable battery to carry elsewhere, you should choose chargeable ones.

Watches, remote controls, baby monitors, and the battery pack in either electric cars or trucks are some examples.

If you own a personal watercraft, this type of battery is also your choice.

On the other hand, with such gadgets as flashlights, smoke alarms, and non-rechargeable batteries are better choices.

  • Battery ratings

The capacity of the battery indicates the amount of power delivered to a device.

More importantly, batteries with a high amount of power allow your gadgets to recharge faster without the risk of overloading, and they have low energy density as well.

Therefore, look at battery ratings on the label to make sure that the battery is suited to your applicants.

  • Shelf life

Without a shade of doubt, normally, not all market batteries are immediately sold and used.

Instead, they may be on the shelf for a long time.

Remaining unused for a long period may diminish the shelf life of the battery and the operating effectiveness.

That’s why we should pay attention to the shelf life indicated on the battery, and choose the quality one.

  • Cost

Batteries seem to be one of the most expensive parts of an electronic gadget.

Nevertheless, not all costly batteries are compatible with your devices and worth your money.

For this reason, before deciding to buy a new battery, let’s visit your applicants’ official stores to get advice and support.

  • Durability

Batteries are often directly affected by various factors, making them fail to work properly. In other words, external factors like humidity, temperature, and magnetic fields can impact your batteries’ performance.

Because of this, to have a durable and effective battery, you should consider those factors and choose the suitable one for your home’s condition.

  • Safety

Safety is always of our utmost priority, so checking the temperature where the battery will work or be installed is an indispensable step.

When being heated up or exposed to flammable items and sunlight, the battery may explode and cause unwanted accidents.

Useful Guide To Use Batteries

Rechargeable batteries

We often use rechargeable batteries for mobile power devices, so how to use these second batteries in the right way?

  1. Avoid overcharging: This is one of the most important methods to prolong the lifespan of the battery. Overall, it would be best to unplug or disconnect the discharger’s battery when the battery is charged fully. If not, you may risk heating the battery and reducing its longevity; worse, making it explode.
  2. Keep the battery away from flammable objects: when recharged, the battery should not be placed on flammable surfaces or items such as pillows, paper, clothes, or curtains. The fire is likely to occur if the battery is heated up or influenced by direct sunlight exposure.
  3. Buy the right device: normally, each battery is compatible with certain types of rechargers. Some rechargers are quite expensive, yet they are durable and can protect the batteries. Besides, mixing the rechargers and batteries may result in unexpected problems. Therefore, spare some time to check the right charger.

Non-rechargeable batteries

The primary batteries have the same tips and guide as the second batteries.

Besides, there is one more precaution involved in recycling and reusing issues.

As non-rechargeable batteries cannot be reused or recharged, users tend to throw them away when they are depleted.

However, this activity is not recommended, as you may cause serious consequences if you do so.

These negative impacts include harming the environment due to the chemical release and adverse influences on human health.

It is because when directly discharged into the ground, the batteries can release a harmful substance.

Therefore, please gather old batteries and bring them to the collecting site for proper disposal.

Frequently Asked Questions
