Not so longer AA batteries were the most common battery size on the market. Massive improvements in microprocessors’ energy efficiency have seen the smaller AAA become more relevant for use in everyday electronics.
If you have a portable electronic device on your right now, more likely than not it’s powered by a AAA battery. Remote controls, alarm clocks, and some of the world’s best digital cameras all use AAA batteries.
Since you are going to be using AAA batteries in devices you most likely use regularly and throughout the lifespan of your toy we recommend you use rechargeable batteries. Imagine all the number of one-use batteries that you are going to throw away before you pack that camera. They will be a lot.
Why you should use AAA rechargeable battery chargers?
They’re Cheaper for you. It doesn’t make sense to spend more when you can save much more money by picking a better option. Single-use batteries are more expensive in the long run. Yes, a rechargeable battery is more expensive to buy at the start but cheaper in the end for you.
The environment should be on everyone’s mind right now. The environmental impact of ordinary batteries is staggering. Battery waste is highly toxic to the environment. Using rechargeable batteries will minimize the level of waste products. A rechargeable battery can be used many times before you need to replace it.
They are very handy for use in most electronic devices. Almost everyone has a device in the house that uses AAA batteries. From your music player to remote control and digital camera these batteries power your fun time.
Most AAA chargers are compatible with many battery brands and types. You can charge your energizer, Panasonic, Duracell, and almost all brands. You must be also able to charge your AA and 9V batteries too with the same charger.
If you like outdoor and camping having rechargeable power will save you a lot of money and keep all your outdoor gear powered up. Most outdoor gear such as flashlights, cameras, and so on need dry batteries, and using a rechargeable option is just better for you and the earth.

The two main types of AAA Battery Chargers
Sometimes the word simple can be a mistake for less. Simple charges still come with excellent features such as overcharge protection. Their simplicity is most apparent in their display. Using only LED lights to indicate when a charge is competed either by turning green from red or turning off from being red when the battery was flat.
Microprocessor controlled chargers
Microprocessors allow for a better LCD display. The display indicates the health status of each individual cell at a time either measured by bars or percentage. The most important feature in this class of charges is the discharge or cycle refresh feature. This feature allows you to reset your battery memory and by doing significantly increasing your lifespan.
What Factors to Consider When Getting a Battery Charger
Wall outlet or USB power source
You need to think carefully about how you will power your device. Most chargers are plug into a wall outlet for a high voltage power source. These are cheaper than those that offer USB adapters so that you can charge your batteries on the go. However, the AC power source is always much faster and is the one I recommend using if you have time. And even when you so busy most chargers have overcharge protection to shut down the charger when your batteries are full. A charger that allows you to charge both at home and in your car is better.
Channels, what you call charging slots
Each of us has our own set of toys. Depending on the many batteries you need to power your device, having enough ports or battery slots will reduce your total charging time altogether. You can charge batteries for your music player, console, and digital camera all at once as you plan for a trip away from home.
Electrical and thermal malfunction protection
Batter explosions have shown the need to have safeguard technology in battery chargers. You need a charger that will automatically cut of charging when you leave your cells in the charger because you fell asleep. A good charger will have protection against overcharge, overheating, short circuits, and power surges.
Portability has to deal with size and power source when it comes to battery chargers. A traveler will need a smaller more compact battery that won’t take up much space in your luggage. If it has both a wall outlet and USB car adapter even better so that you can charge your cells on the go. You may also use your laptop USB port as a power source but it will be slower to charge and may not reach full charge.

You need to read your user manual to get a good understanding of the operational procedures.
How long do I have to wait for a complete charge?
Is not a straightforward answer question. The best I can say is that it depends on your battery capacity and charge rate. The smaller your charge rate the longer it takes to reach a full charge. And the higher your battery capacity the more time you need to charge it. On average a super-fast charger will take 4 hours to fully charge AA and AAA batteries. The larger battery types like the 6 and 9 V need as much as 10 to 12 hours to get a full charge. With experience, you will see how long your batteries take to charge in your circumstances.
Can I charge all types of batteries with my charger?
This is something you have to pay very close attention to. Most chargers are limited in the types of batteries they can charge. The chemistry of each battery type is very unique and the type and duration of charge can either prolong your battery life or kill it. Using rechargeable batteries is best used with chargers from the same brand if you a newbie. But if you have a universal type then make sure it’s designed to charge that type. Sometimes you will find that your charge only charges Ni-MH batteries but will destroy lithium ion-based cells. Your manual will tell you right away the type of batteries compatible.
What is a battery recycling location and how do I find one?
We strongly advocate for the recycling go dead batteries that can no longer hold a charge. We are facing unprecedented levels of environmental challenges that seem to threaten our very existence. The earth is facing pollution multiple chemical assaults both in the air and on the ground and under. How we dispose of our waste is critical.
