What's the difference between 1.2V and 1.5V rechargeable batteries? Is it a battery? Can it be used?

In recent years, with the progress of science and technology, we are gradually surrounded by all kinds of new products and technologies, making our daily life easier and more convenient.

Take the battery that is often used in family life and often appears in our sight. Ten years ago, we used the disposable dry battery. If we throw it away once, it will not be environmentally friendly.

But now, rechargeable batteries are beginning to take the place of disposable dry batteries.

After all, who wouldn't love a USB rechargeable battery that can be recharged hundreds or even thousands of times, and is as cost-effective as hundreds of ordinary batteries?

And often buy rechargeable batteries or rechargeable batteries have a certain understanding of a lot of friends will notice this situation, that is, a lot of rechargeable batteries have 1.2V and 1.5V these two different nominal, which brings a lot of questions, such as: what is the difference between 1.2V and 1.5V rechargeable batteries? Is it a battery? Can it be used? And so on.

So today we are going to solve the puzzle for you! Explore the differences between 1.2V and 1.5V batteries!

Is there any difference between 1.2V and 1.5V rechargeable batteries?

A: The 1.2V label is indeed a rechargeable battery, but the 1.5V label is generally a non-rechargeable dry battery.

The potential difference between oxygen and hydrogen in a dry cell is 1.5V, while that in a rechargeable cell is 1.2V

Nickel-metal hydride and nickel-cadmium battery operating voltage is generally between 1-1.4V, the average voltage is 1.2V, less than 1V indicates overdischarge.

Lithium batteries are mainly 3-4.2V with an average voltage of 3.6-3.7V.

Are they the same kind of battery?

A: No, 1.2V rechargeable batteries can be reused for multiple times, including nickel-hydrogen and nickel-cadmium, while 1.5V disposable batteries can not be recharged, generally rely on acid and alkaline to classify them.

Normally, disposable batteries, regardless of their nature, have a nominal voltage of 1.5V, while the current common rechargeable batteries have a voltage of 1.2V.

These 1.5V and 1.2V are the nominal voltages of the two batteries, but not the actual voltages.

Are the two kinds of batteries used here?

A: 1.2V and 1.5V batteries can be used.
