If your household is like mine you probably have a ton of electronic devices that require the best rechargeable AA batteries.
This is especially true if you have a young family. Anything and everything from walkie-talkies to baby monitors, stealth drones, LEGO trains, security cameras, and even remote control cars all require AA batteries.
So many things today, even baby crib mobiles, rely on battery power.
When these devices run out of battery juice, you can be in a world of trouble.
What’s even more frustrating is when you run out of batteries completely and don’t have any available to replace the dead ones with.
All of a sudden you have to run out to the store to purchase new AA batteries so you can power up devices to soothe your baby to dream land.
On top of the struggle to track new batteries down, it can be overwhelming to change them. You have to constantly unscrew those battery compartments with those tiny screwdrivers (with screws you can barely see) to change the batteries when they die.
Well it doesn’t have to be that way.
By organizing your household and going through all your batteries, you can actually save money.
There are other options and alternatives such as rechargeable AA batteries.
Before we take a look at what the best brands of rechargeable AA batteries are let’s see when buying rechargeable AA batteries make sense.
What Are Rechargeable Batteries?
Rechargeable batteries are energy storage devices that have the ability to be reused hundreds of times. Surprisingly rechargeable batteries have been in existence since 1859.
Most of the rechargeable batteries today are made of Nickel Metal Hydride (NiMH).
A lot of the rechargeable batteries on the market today can hold a charge for a year or longer. When rechargeable batteries first came out, there were problems with keeping their charge. When you went to use the battery, it was dead. It lost all of its power capacity while sitting on the shelf.
That is not the case anymore.
Some of the rechargeable battery manufacturers market their batteries to have a shelf life of five years or more today. Some rechargeable AA batteries will hold their charge today if stored during that amount of time.
Using rechargeable batteries is one way how to save money using solar power since they can be charged and reused.
How Are Rechargeable Batteries Different Than Alkaline Batteries?
Rechargeable batteries are different than alkaline batteries because they have a higher capacity of power.
Rechargeable AA batteries have capacity of 1,000 to 3,200 mAh (milliamp hours) of power capacity.
Alkaline batteries are different as they generally have around 2,400 mAh.
Another difference is with these high-capacity rechargeable AA batteries, they have more power capacity to use for high powered devices for things such as drones.
Alkaline batteries are one of the things I stopped buying in my household to save money. Those batteries are not a good fit for high-powered devices such as remote control cars, drones, or video cameras.
Are Rechargeable AA Batteries Worth It?
That answer can be a complex one to answer. There are times that rechargeable AA batteries are worth it and other times when they are not. We have broken out the pros and cons below of when rechargeable batteries pay as an investment and when they don’t.
When Rechargeable Batteries Are A Good Investment
From an environmental standpoint, rechargeable AA batteries absolutely are worth it.
According to the Environmental Protection Agency Americans throwaway 180,000 tons of batteries each year.
The demand for batteries can be attributed to the increase in portable products such as battery powered tools, electronic products, and toys. If you plan to build your own PC, you will need batteries for your mouse and wifi components.
These batteries that are thrown out may contain toxins such as mercury and cadmium which is a potential threat to not only the environment, but also to human health if they are not disposed of properly.
Additionally, if you buy batteries through shopping sites such as Rakuten, you will receive cash back on your purchase!

When Rechargeable Batteries Don’t Make Sense
Figuring out if rechargeable AA batteries make sense also depends on what your need is. If you are looking to power devices that draw a low current, it may not make sense to use rechargeable batteries.
Devices such as clocks, pocket flashlights, and some thermostats don’t use a lot of current.
You could buy AA alkaline batteries much cheaper than what rechargeable AA batteries would cost. If you did end up using rechargeable AA batteries in those devices, it would take years for that investment to pay off.
Sometimes alkaline batteries can last for 1 to 2 years in some of these low current devices.
How Long Do Rechargeable AA Batteries Last?
NiMH rechargeable AA batteries will last for 500 to 1,000 charges which is approximately 2 to 3 years. The battery should be charged and used often. When not in use you should store them in a cool and dry place.
One good thing about rechargeable batteries is that the more you use and charge them the longer they will last.
They could potentially last up to a decade if you follow the correct care and usage instructions. That’s almost as good as receiving free stickers from companies in the mail!
Is It Possible To Overcharge Rechargeable Batteries?
It is not good if you over charge your rechargeable batteries. When this happens, rechargeable batteries experience a loss of their holding capacity every time they are overcharged. It is best to use a charger that has an automatic shut off once the battery reaches its charging capacity.
What Are The Best Rechargeable AA Batteries You Can Buy?
Below we will compare several brands of rechargeable AA batteries. We will compare the features of price, charge capacity (mAh), and shelf life (discharge rates).
So be sure to take a look below at our comprehensive guide below on the best AA rechargeable batteries on the market.
Panasonic Eneloop AA Rechargeable Batteries

These batteries also come pre-charged and can be ready to use out of the box. Another great feature is that they can hold 70% of their charge for up to 10 years which is hard to beat by any other rechargeable battery manufacturer.
Panasonic Eneloop Pro AA Rechargeable Batteries
The Eneloop Pro AA Rechargeable Batteries also by Panasonic can deliver a lot of performance. The Panasonic Eneloop Pro rechargeable batteries were designed with high-performance and high-drain devices in mind. They are a great option for the best rechargeable AA batteries for things such as a DSLR camera, or a wireless keyboard and mouse.

What About A Battery Charger?
When thinking about a battery charger it is important to look at a few things.
The first question to answer is “how many batteries does your household routinely use?”
The answer to this question determines how many batteries you should charge at a time. An advatage of today’s AA rechargeable batteries is that most of them have a long shelf-life. Meaning you can charge up a bunch and keep some ready to go with only minimal power capacity degrades. That’s important.
The second question is “how much time do you want to spend charging batteries?”
Although you may think this is not an important question to ask, it is really vital to know the answer. You may think that no big deal when my batteries are dead I will just stick them on the charger.
Consider that the average gaming system remote takes 2 batteries, a Roku remote also takes 2, and a TV remote takes 2. That is a total of 6 batteries JUST in those three everyday devices. I hate to break it to you but most chargers can only handle 4 batteries.
So your either going to have to take the time out and charge up a max of 4 at a time, or consider buying a larger battery charger with the capacity to charge many batteries at the same time.
Best AA Rechargeable Battery Brands
When it comes to the best rechargeable batteries on the market, these picks above definitely offer advantages. Most of them contain a high mAh battery capacity, low drain, and are also great choices for the environment over traditional alkaline batteries.
Whatever your power needs for your electronic devices, the brands mentioned above would be considered some of the best rechargeable AA batteries on the market.
By choosing the appropriate batteries for your portable power needs, you will not only be saving money, but will be saving the environment as well by keeping batteries out of the landfills. That is a welcomed benefit for all generations; past, present, and future.
Reusing rechargeable batteries over and over will save you money, the environment, and also time. With all of those benefits, it’s almost impossible to say no to investing in rechargeable batteries.
