If you are like most people, you have a device that requires aa batteries. You probably also have a bunch of old aa batteries lying around that are no longer usable. In this article, we will discuss why aa rechargeable batteries are 1.2 v and how this can be beneficial to you.
So, why are aa rechargeable batteries 1.2 v?
The AA size battery is available in three different chemistries: alkaline, NiCad, and NiMH. Each one of these has a different nominal voltage. Alkaline batteries have a nominal voltage of 1.5 or 1.6 volts, NiCad batteries have a nominal voltage of 1.2 volts, and NiMH batteries have a nominal voltage of 1.2 volts.
Let’s dig into it and see what we can learn.

Are All Rechargeable Aa Batteries 1.2 V?
No, not all AA batteries are 1.2 volts. Some are 1.5 volts and some are 1.2 volts.
As well as that, The proper voltage for an AA/AAA alkaline battery is 1.5V. The proper voltage for an AA/AAA NiCd/NiMh rechargeable battery is 1.25 Volts. These are both great types of batteries.
Will 1.2 V Batteries Work Instead Of 1.5 V?
This is a great question! 1.2 V batteries will work in most devices that require 1.5 V batteries, but they will not last as long as 1.5 V batteries. 1.2 V batteries are typically used in smaller devices, such as watches, calculators, and remote control cars.
An additional, You can use 1.2 V rechargeable batteries in devices that usually take 1.5 V throw away batteries. There is no effect on the use of the equipment. In fact, an alkaline battery only benefits from 1.5 V voltage at the beginning of its discharge.
Why There Are No 1.5 V Rechargeable Batteries?
This is a question that we get asked a lot here at Battery Junction, and it’s a valid question! After all, there are 1.5 volt AA, AAA, C, and D batteries, so why not a 1.5 volt AA or AAA rechargeable battery?
The answer has to do with the chemistry of the different types of batteries. The 1.5 volt AA and AAA batteries are alkaline batteries, which means that they use a different chemical reaction to create the electrical current than the 1.2 volt AA and AAA rechargeable batteries.
The 1.2 volt AA and AAA rechargeable batteries are nickel-metal hydride batteries, which means that they use a chemical reaction that is not compatible with the 1.5 volt AA and AAA batteries. So, while you can use a 1.2 volt AA or AAA rechargeable battery in place of a 1.5 volt AA or AAA battery, you cannot use a 1.5 volt AA or AAA battery in place of a 1.2 volt AA or AAA rechargeable battery.
We hope that this article has helped to clear up any confusion that you may have had about 1.5 volt AA and AAA batteries! If you have any further questions, please feel free to contact us and we’ll be happy to help.
Additionally, Batteries are made up of cells. Each cell has a nominal voltage, which is the average voltage it produces. When a cell is fully charged, it produces a higher voltage than when it is fully discharged. The difference in voltage is due to the chemistry of the cell.
Do Rechargeable Batteries Come In 1.5 V?
No, rechargeable batteries do not come in 1.5 volt sizes. The standard voltage for a rechargeable battery is 3.6 volts.
Additionally, Yes, they are finally available. A company called Kentli has released AA and AAA rechargeable lithium polymer batteries that output 1.5 volts.
1.2V Vs 1.5V Rechargeable Aaa Batteries, Which One Is Better?

This is the voltage that is typically needed to power most electronic devices.
How To Choose The Best Rechargeable Battery For You?
When it comes to batteries, there are a lot of options out there. So, how do you choose the best rechargeable battery for you? Here are a few things to keep in mind:
1. The type of device you’re using: Some devices, like digital cameras, require a specific type of battery. Make sure to check what type of battery your device uses before making a purchase.
2. The size of the battery: Batteries come in a variety of sizes, so you’ll want to make sure you get one that’s the right size for your device.
3. The capacity of the battery: This is how much power the battery can store. The higher the capacity, the longer the battery will last before needing to be recharged.
4. The price: Rechargeable batteries can range in price, so you’ll want to find one that’s affordable for you.
5. The warranty: Some companies offer warranties on their batteries. This can be helpful if you have any issues with the battery down the road.
Keep these things in mind when choosing a rechargeable battery and you’ll be sure to find the perfect one for you.
When To Choose Rechargeable Batteries Over Disposable?
Batteries are an essential part of life in the 21st century – we use them in everything from our electronic devices to our cars. But with so many different types of batteries on the market, it can be hard to know which one is right for you. Should you choose disposable or rechargeable batteries?
There are pros and cons to both types of batteries, so it really depends on your individual needs. If you need a battery for something that you use infrequently, like a flashlight, then disposable batteries are probably the way to go. They’re also a good choice if you need a battery that will last for a long time without being used – for example, if you’re going on a camping trip and need a battery for your flashlight that will last the whole trip.
Rechargeable batteries are a good choice if you use a lot of batteries or if you need a battery that will last for a long time without being used. They’re also a good choice if you need a battery that you can recharge quickly – for example, if you’re using a wireless mouse that runs out of battery power quickly.
So, which type of battery is right for you? It really depends on your individual needs. If you’re not sure, it’s always a good idea to ask a professional or do some research to find out which type of battery will best suit your needs.
What Are Some Signs That A Aa Rechargeable Battery Needs To Be Replaced?
If your AA battery isn’t holding a charge like it used to, it might be time to replace it. Other signs that a AA battery needs to be replaced include:
-The battery doesn’t work in any devices
-The battery only works for a short time after being charged
-The battery swells up
-There is leakage from the battery
Final Word
In conclusion, the reason that AA rechargeable batteries are 1.2 volts is because they are made up of six individual cells that each have a voltage of 2.0 volts. When these cells are connected in series, the overall voltage is reduced to 1.2 volts.
There are a few key factors you need to consider before taking a final decision.
- Rechargeable batteries are a more sustainable option than disposable batteries.
- They can be used multiple times, which saves money in The long run.
- Rechargeable batteries typically have a longer lifespan than disposable batteries.
- They can be recharged quickly and easily.
- Most Rechargeable batteries are now available in sizes that fit AA devices.

FAQs
Why Are Aa Rechargeable Batteries 1.2 V? [Updated On- 2023]? ›
It is to do with the chemistry. Alkaline and zinc-carbon cells have a chemistry that develops 1.5v. NiCd and NiMH cells only develop around 1.2v per cell. The trade off is less potential difference in exchange for being rechargeable.
Why are rechargeable AA batteries 1.2 V instead of 1.5 V? ›It is to do with the chemistry. Alkaline and zinc-carbon cells have a chemistry that develops 1.5v. NiCd and NiMH cells only develop around 1.2v per cell. The trade off is less potential difference in exchange for being rechargeable.
Can I use a 1.5 V batteries instead of 1.2 V? ›Yes, most definitely. Using 1.2 V rechargeable batteries will have no effect on the use of the equipment. In fact an alkaline battery only benefits from 1.5 V voltage at the beginning of its discharge. Then, it drops constantly to well below 1.2 V.
Are all NiMH batteries 1.2 V? ›NiMH AAA battery capacity
As is true of every NiMH battery, they're rated to run at 1.2 V, which we confirmed in our testing. And like most of the AAAs we tested, they have a capacity rating of 1,100 mAh.
Depending on the size and chemistry of the battery, the voltage can vary significantly (1.5V for common alkaline batteries such as AA, AAA cells, 3V for small lithium coins or 9V for 9V batteries).
What happens if I replace a 1.2 volt battery with a 1.5 volt battery? ›Usually nothing, the device might be a bit more powerful. However if you have a device that is designed to take 10x 1.2v batteries and you use 1.5v batteries then instead of 12v you are providing 15v. In devices where this voltage difference could cause damage you insert 2x "dummy cells" to retain 12v.
