There are various kinds of batteries you can use as a source of energy to power up your electrical tools, gadgets, and more. One of the most common is the AA battery, which also has different types. If you are using this battery, you need to find out everything there is to know about AA batteries to maximize their energy and ensure you use the right one.

A Complete Guide to AA Batteries

What is an AA Battery?

An AA battery is like other batteries that convert chemical energy into electrical energy. Its measure is about 1.94 to 1.99 in length and has a diameter of 0.57 in. Because of its small size and not having a too high voltage compared to other batteries, it is usually used in small household electronic devices like remote controls, clocks, flashlights, toys, etc. Its parts consist of a container, cathode, anode, separator, collector, electrodes, and electrolyte. They all have essential functions in making a double-A battery work.

Common Types of AA Batteries

When buying an AA battery, you have to consider which type is the best for its purpose. You have to search for what’s appropriate for your electronics and choose one that will work best. Below are some of the most popular options you can find in the market.

Alkaline Batteries

Alkaline batteries contain energy that comes from the reaction of manganese dioxide and zinc. These batteries are most suitable for items that require low power, such as alarm clocks and toys. Although there are alkaline batteries that are designed to be rechargeable, most types that are common are non-rechargeable. Yet, many individuals with knowledge about batteries still tend to buy an alkaline one for their battery-operated device because its power can last long and has a long shelf-life. You just have to make sure it is properly stored to avoid leakage over time.

Lithium-Ion Batteries

Lithium-ion batteries, also known as Li-ion batteries, are rechargeable sources of energy. They are convenient to use, especially because you don’t have to buy a new one once they run out of power; You just need to charge them. A Li-ion battery is also more costly than an alkaline battery. But if you need a pack of batteries for a device you will constantly use, its power and performance will be worthy of your purchase. In addition, it’s not prone to leaking.

Since a lithium-ion battery has an extremely high energy density, it is ideal for digital cameras, and wireless devices such as wireless doorbells and thermostats. Plus, it has a built-in feature that prevents it from overheating, making your gadget less prone to breaking.

On the other side, there are also lithium non-ion batteries which have a significant difference from the ion batteries. Although they are long-lasting compared to other regular batteries, they are not built to be recharged.

Nickel Metal Hydride (NiMH) Batteries

If you are looking for batteries that you can reuse, many other rechargeable batteries are available, including NiMH batteries. This type is one of the common products in stores and is preferred by people who want an affordable yet quality battery. In addition, it is also considered an excellent alternative to alkaline batteries. Of course, you want your batteries to be convenient to use and save money from frequently buying them. However, its power doesn’t last that long, and it is not suitable for devices that require a high voltage.

How Long Do AA Batteries Last?

The longevity of double-A batteries is affected by different factors such as the type, the voltage, and where you will use them. Of course, if you use a high-voltage AA battery in a device that requires minimal energy, it can last for so long. On the other hand, if you use an AA battery in something that consumes a large amount of electrical energy, it won’t last that much. But it will still depend on how great energy your device is consuming.

But if you want to maximize the performance of the battery and truly save money, you have to know what type of battery has the features that suit your electronic devices’ needs. When you need temporary batteries for devices you won’t frequently use, you can get an alkaline one. If you will always use your device, but it doesn’t require much power, you can get rechargeable batteries like NiMH. Lastly, if you will often use it on a device that requires great power, lithium-ion batteries are advisable.

You can also keep the battery life longer if you know how to properly store it. To do that, you have to keep your batteries’ packaging unopened and keep them in a dry place at room temperature. In addition, you should not mix the new batteries with the old ones.

Where Can You Purchase Double-A Batteries?

AA batteries are not really that hard to find. There are various brands in supermarkets, hardware, and other stores. You can conveniently get rechargeable and non-rechargeable in most shops. However, the brand might vary per store. Besides that, you can even search for an online shop and purchase packs or bulk.
