The difference between a micro AAA battery and an AAA battery is the size. Micro AAA batteries are about half the size of an AAA battery. They are designed for devices that need a small, powerful battery, such as hearing aids and watches.

While AAA batteries will also work in these devices, they may be too big and bulky.

When it comes to AAA batteries, there are two main types: micro AAA and AAA. Both have their own set of benefits and drawbacks, so it’s important to choose the right type for your needs. Here’s a quick rundown of each type of battery:

Micro AAA batteries are smaller than standard AAA batteries, making them ideal for use in devices that have limited space. They also tend to be more expensive than standard AAA batteries. AAA batteries are the most common type of battery used in household devices.

They’re larger than micro AAA batteries, so a higher mAh battery will last longer and provide more power. However, they’re also more likely to leak and can be harder to find in stores.

What is an AAA Micro Battery?

A AAA micro battery is a small, cylindrical battery that typically provides 1.5 volts of power. These batteries are used in a variety of electronic devices, including calculators, remote controls, and LED lights where solar powered lights stay on long time. AAA micro batteries are also known as button cell batteries or coin cell batteries.

Button cell batteries get their name from the fact that they often have a small raised button on the top of the battery, which is used to make contact with the device’s electrical contacts. Coin cell batteries derive their name from their resemblance to coins. Both types of AAA micro batteries are about the same size as a US quarter (24 mm in diameter and 5 mm thick).

While AAA micro batteries are relatively small and lightweight, they pack quite a punch when it comes to power. A single AAA micro battery can provide enough power for an LED light to run for several hours or for remote control to work for weeks at a time. And because they’re so common, AAA micro batteries are easy to find and relatively inexpensive.

Are There Different Types of AAA Batteries?

Yes, there are different types of AAA batteries. The three most common types are alkaline, lithium, and rechargeable. Each type has its own benefits and drawbacks.

Alkaline batteries are the most common type of AAA battery. They’re inexpensive and have a long shelf life. However, they don’t perform as well as lithium or rechargeable batteries in high-drain devices.

Lithium AAA batteries are more expensive than alkaline, but they offer better performance in high-drain devices. They also have a longer shelf life than alkaline batteries. However, they can be dangerous if damaged or used improperly.

Rechargeable AAA batteries are the most expensive option, but they’re also the most versatile. You can reuse them over and over again, which saves money in the long run. They also perform well in high-drain devices.

Is There a Smaller Battery Than a AAA?

No, there is not a smaller battery than a AAA. The AAA battery is the smallest size that is commercially available. There are even smaller batteries used in some electronic devices, but these are not widely available to consumers.

What is the Difference Between AAA Batteries?

There are a few key differences between AAA batteries.

  • Firstly, AAA batteries are typically smaller and lighter than AA batteries.
  • Secondly, AAA batteries have a higher capacity than AA batteries – meaning they can store more energy and will last longer.
  • Finally, AAA batteries have a higher voltage than AA batteries, which means they can provide more power for devices that require it.

AAA Vs AA Battery

Do you know the difference between AA and AAA batteries? If not, you’re not alone. Though these two types of batteries are both incredibly common, many people don’t know the key differences between them.

Here’s a quick rundown of the main points: AA batteries are larger than AAA batteries. AA batteries have more capacity than AAA batteries. AA batteries can power devices for longer than AAA batteries.

AAA Battery Voltage Chart

Batteries come in all shapes and sizes, and each has its own voltage. The most common battery voltages are 1.5 V, 3 V, 6 V, 9 V, and 12 V. AA batteries have a voltage of 1.5 V. AAA batteries have a voltage of 3 V. C batteries have a voltage of 9 V. D batteries have a voltage of 12V. The capacity of a battery is measured in amp hours (Ah).

The higher the Ah rating, the longer the battery will last before needing to be recharged or replaced. A typical AA battery has an Ah rating of 2200 mAh, while AAA batteries have an Ah rating of 1000 mAh. When choosing a battery for your application, it is important to consider both the voltage and capacity requirements.

If you need a long-lasting power source, choose a battery with a high Ah rating. If you need lots of power for a short period of time, choose a battery with a high voltage.

AAA Battery Capacity

Batteries come in all shapes and sizes, but AAA batteries are some of the most popular. These small, cylindrical batteries are often used in electronic devices like remote controls, digital cameras, and portable audio players. But what exactly is the capacity of a AAA battery?

The capacity of a battery is measured in milliamp hours (mAh). This refers to the amount of time that a battery can provide a certain amount of current before it needs to be recharged. A higher mAh rating means that a battery can provide more power for longer periods of time.

AAA batteries typically have capacities between 600 and 1200 mAh. This means that they can provide between 0.6 and 1.2 amps for one hour before needing to be recharged. Of course, actual performance will vary depending on the device being powered and how frequently it is used.

If you’re looking for long-lasting power in a small package, AAA batteries are a great option. Just be sure to check the mAh rating to make sure you’re getting the right type of battery for your needs.

Types of AAA Batteries

AAA batteries come in a variety of shapes and sizes.

The Most Common Type

The most common type is the cylindrical, or round, battery. These batteries are typically used in small electronic devices, such as remote controls and flashlights.

Another Common Type

Another common type of AAA battery is the rectangular prismatic battery. These batteries are often used in larger electronic devices, such as laptops and digital cameras. The size and shape of an AAA battery determine its capacity, or how long it will power a device before needing to be replaced.

The capacity of a cylindrical AAA battery is typically about 1,500 mAh, while a rectangular prismatic AAA battery can have a capacity of up to 3,000 mAh.

AAA Battery Life

Batteries are one of those things that we often take for granted. We use them every day in our electronic devices, and we expect them to just work. But have you ever wondered how long your batteries actually last?

The answer, of course, depends on the type of battery and how it’s used. For example, a AA battery can last anywhere from 1,500 to 3,000 hours when used in a low-drain device like a remote control. But if you’re using it in something that requires more power, like a digital camera, it may only last 500 to 1,000 hours.

There are several factors that affect battery life, including Type of Battery: There are many different types of batteries on the market today (e.g., lithium-ion, alkaline, etc.), and each has its own strengths and weaknesses. For example, lithium-ion batteries tend to have a longer lifespan than alkaline batteries but they’re also more expensive.

How the Battery is Used: As mentioned above, how you use your battery will affect how long it lasts. If you frequently drain your battery by using high-powered devices or leaving it on standby mode for extended periods of time, it will not last as long as if you were using it more sparingly. Storage Conditions: Batteries should be stored in a cool and dry place to prolong their life.

Extreme temperatures can shorten the lifespan of a battery significantly. Manufacturer: Not all manufacturers are created equal! Some brands simply make better quality products than others.

Do some research to find out which brands have the best reputation for making long-lasting batteries.

AAA Battery Voltage And Current

AAA Batteries have a voltage of 1.5 volts and a current of 2,600 mAh. The capacity of a battery is usually determined by the amount of time it can provide power for a given discharge rate. For instance, a battery with a capacity of 2,600mAh can theoretically last for one hour if discharged at 2.6 amps.

AAA Battery Size

The AA battery is the most popular size of the battery in the world. More than three billion AA batteries are produced each year. The AA battery gets its name from the International Electrotechnical Commission (IEC).

The IEC uses a lettering system to designate different sizes of batteries. The “A” in AA battery stands for “Alkaline.” The AA battery is sometimes referred to as a double A or Mignon (French for “cute” or “adorable”) battery.

AA batteries are available in a variety of chemistries, including alkaline, lithium, nickel-metal hydride (NiMH), and zinc-carbon. Alkaline batteries are the most common type of AA battery; they are inexpensive and have a long shelf life. Lithium AA batteries are more expensive than alkaline batteries but they last longer and can operate in extreme temperatures.

NiMH AA batteries can be recharged hundreds of times but they self-discharge when not in use, so they must be recharged before use. Zinc-carbon AA batteries are the least expensive but also have the shortest lifespan and low discharge rates. AA batteries come in standard and high-capacity varieties.

Standard-capacity AA alkaline batteries have a capacity of about 2,500 to 3,000 milliamp hours (mAh), while high-capacity AA alkaline batteries have a capacity of 4,000 to 8,400 mAh. Lithium AA batteries also come in standard and high capacities; however, their capacities are much higher than those of alkaline AA batteries—about 8,000 to 12,000 mAh for standard lithium AAs and 9,000 to 28,000 mAh for high-capacity lithium AAs! NiMH and zinc-carbon AA cells also vary in capacity; NiMH generally has slightly lower capacities than lithium-ion while zinc-carbon usually has lower capacities than both types of cells.


Are All AAA Batteries the Same Size?

Are All AAA Batteries the Same Size? The short answer is no, not all AAA batteries are the same size. However, they are close enough in size that they can usually be used interchangeably in devices.

The most common AAA battery size is known as the ANSI/NEDA 13A or IEC LR03, which measures 44.5 mm in length and 10.5 mm in diameter. There are also some AAA batteries that are slightly shorter and wider, known as the AA1/3N or IEC LR6, which measure 42.5 mm in length and 14.5 mm in diameter. While most AAA batteries will fit into devices designed for use with AAA batteries, it is important to check the specifications of your device to ensure that it can accommodate AA1/3N batteries before using them.

Additionally, keep in mind that using AA1/3N batteries in a device designed for use with AAA batteries may result in reduced performance or shortened battery life.


A micro AAA battery is a type of AAA battery that is smaller in size than a traditional AAA battery. While a traditional AAA battery measures 44.5 mm in diameter, a micro AAA battery only measures 36 mm in diameter. Despite its smaller size, a micro AAA battery still has the same voltage as a traditional AAA battery (1.5 volts).

The main advantage of using a micro AAA battery over a traditional AAA battery is that it takes up less space. This can be beneficial if you need to save space in your electronic device, such as when using AA batteries would be too bulky. Additionally, since microAAA batteries are lighter than AAAs, they may also reduce shipping costs for some devices.
