AA vs AAA Battery: What Are the Differences?


Not sure which batteries to choose? It can be hard to keep track of the differences in the AA vs AAA battery argument, especially when you’re in a hurry.

You know that using the wrong battery type in your device can be a disaster, but what are the real differences between AA and AAA batteries?

In short, AA batteries are bigger than AAA batteries. They also last longer and have more power.

So, which type of battery is right for you? It really depends on your needs.

That’s why we created this article which is a AA battery guide and a AAA battery guide at the same time.

Read on for more details.

What Is the Difference?

The main difference between AA and AAA batteries is their size and capacity. AA batteries are typically larger, meaning they can power devices for longer periods of time before needing to be replaced.

AAA batteries tend to be smaller and have less capacity, making them ideal for devices that don’t require a lot of power.

AA batteries also tend to be more expensive than AAA batteries, though this difference is often not very significant. Ultimately, it’s up to the user to decide which type of battery is best for their needs.

Are They Made of the Same Stuff?

Are they made of the same stuff? This is a question often asked about AA and AAA batteries. While both types of batteries are made of chemicals, the type of chemical used can vary depending on the battery.

AA batteries generally use alkaline chemistries, while AAA batteries typically use lithium or other more specialized chemistries.

This makes AA batteries better suited for high-drain devices like digital cameras, while AAA batteries are better suited for low-drain devices like remote controls.

So, while the two types of batteries may look alike, the materials used to make them can be quite different.

They Are Not Always Interchangeable

Just about everyone has a use for AA or AAA batteries. These common batteries power everything from remote controls to smoke detectors.

While AA and AAA batteries are similar in many ways, it’s important to note that they are not always interchangeable.

Some devices require one or the other, so be sure to check your device’s requirements before purchasing batteries. With that said, AA and AAA batteries are both widely available and will work in most common devices.

So whether you need AA or AAA batteries, you’re sure to find what you’re looking for.

What Types of Devices Use AA Batteries?

AA batteries are commonly used in high-drain devices like digital cameras, portable CD players, and handheld gaming consoles. They’re also often used in larger devices like smoke detectors and wireless keyboards.

In general, any device that requires a lot of power will likely use AA batteries.

What Types of Devices Use AAA Batteries?

AAA batteries are most commonly used in low-drain devices like remote controls, remote control toys, digital thermometers, and laser pointers. They’re also occasionally used in high-drain devices like digital cameras.

But this is less common due to their lower capacity. AAA batteries are typically made of alkaline or lithium, with alkaline being the most common.

Alkaline AAA batteries are usually suitable for low-drain devices, while lithium AAA batteries are generally better suited for high-drain devices.

Do AA and AAA Batteries Have the Same Voltage?

The answer is yes! Both AA and AAA batteries have a voltage of 1.5 volts. This is the standard voltage for all consumer batteries.

There are some exceptions to this, however. Some high-powered devices may require AA batteries because they need more power.

How Many Times Can I Recharge an AA or AAA Rechargeable Battery?

Rechargeable batteries are a great way to save money and reduce waste, but they can only be used so many times before they need to be replaced. AA and AAA batteries can be recharged multiple times.

However, it’s worth noting that each recharge will reduce the capacity of the battery. Eventually, the battery will no longer hold a charge and will need to be replaced.

For best results, only recharge your batteries when they’re completely depleted. This will help to prolong the life of your batteries and save you money in the long run.

Can I Use AA Batteries in AAA Devices?

It depends on the device. Some devices will work with either AA or AAA batteries, but others are designed specifically for one type. Check your device’s specifications to be sure. 

Do AA and AAA Batteries Have the Same Shelf Life?

No, AA and AAA batteries do not have the same shelf life. An AA battery typically has a longer shelf life than an AAA battery, meaning it will retain its charge for longer when not in use.

What About AAA Car Batteries?

Are AAA car batteries good? In general, AAA batteries will work just as well as any other car battery. 

Generally, AAA car battery prices are lower than those at any local store, and they’re available quickly to get you back on the road with as little fuss as possible. AAA technicians are available to do the work for you while you relax, safe in the knowledge that the job is being done properly.

Also, taking away and disposing of your old battery is included in the price of your new battery rather than being charged additionally.

If you’re ever in a bind and need a new car battery, you can always rely on AAA. Their battery service is one hundred percent mobile, so you don’t have to go to them; they’ll come to you.

Their technicians are very prompt and can usually have your new battery swapped within fifteen minutes. Plus, their coverage extends close to home and even to vacation spots, so you’re never too far from AAA’s service.

Do You Understand the Difference Between the AA vs AAA Battery?

So, there you have it! The next time you go to pick up batteries, now you’ll know which ones are right for the job.

When it comes to AA vs AAA battery, choose wisely! And be sure to check our blog for more articles like this one. Thanks for reading!
