Learning the Basics of AA Battery Voltage Range

AA batteries plays a huge role on the daily routine of almost all households. They may seem to be small, but they are behind of a lot of activities within the house. You will commonly see on battery powered toys, wall clocks, television remote and various electronic devices. These batteries have been with us through the entire course of our modern life. I mean who doesn’t recognize the Energizer Bunny?!

For decades, we are using AA batteries to power out trusted, handy electronic devices at home or at work. They also evolved along with our growth to offer better performance through the years. One innovation that is very helpful to use is the introduction of rechargeable AA batteries. As progress comes along, they slowly improve offering higher storage capacity and longer life expectancy. However, no matter what upgrades they’ve had, it seems that users expect more. In this article we are going to study the basics of a AA battery voltage range and other important information, allowing us to understand the limitations that they have.

To begin understanding these batteries, we start of by defining them and learning what they are made of.

What is A AA Battery?

AA batteries are standard sized dry cell batteries composed of a singular electrochemical battery cell that either be disposable or rechargeable. These batteries are widely used to power various portable electronic devices with capacity and voltage that vary according to the chemistry of the battery cell. But typically, the devices using these batteries are designed to only take 1.5 volts.

The American National Standards Institute or ANSI standardized the size of AA batteries in 10947 but they were introduced 1907. A battery with the AA size measures 1.94 to 1.99 inches lengthwise and 0.53 to 0.57 inches diameter wise. The weight of a AA battery also varies according to its cell’s chemistry and they are listed below:

● Alkaline AA Battery – Roughly 23 grams
● Lithium-Ion AA Cell – About 15 grams (Not Applicable)
● Ni-MH AA Battery – Around 31 grams

Understanding How These Batteries Work and Their Range


End voltage is defined as the amount voltage within the cell where it is considered to be depleted. Once this remaining amount of voltage within the battery cell, it will lose its ability to store charge. Then the deterioration of the cell begins.

The specific voltage of a AA battery is different depending on the chemical structure of the cell within it. But the typical end voltage is normally considered as 90% of the initial voltage of the battery. With that said, the best method to determine the end voltage of a battery is by application.

To understand this theory. Let us take a look at it this way.

Most electronic devices are designed to have a specific amount of voltage that causes it to fail. This is the point where the device will prevent improper functions by cutting itself off, if the device is powered by multiple batteries, that amount will be total voltage divided by the number AA cells. The range of this amount of voltage for portable devices is typically between 1.0 volts to 1.1 volts and can even go down to 0.9 volts.

The battery review website has mentioned that when the devices have lower amounts of end voltage, this will allow them to operate longer with a single charge. This is why manufacturers of disposable batteries prefer showing the discharge curve against time rather than the Amp hours. Another reason is the varying capacity of batteries based on the current discharge rate.

Digging A Little Deeper on the Range of the Batteries


The obvious thing that we will see with regards to this issue is that batteries have varying range depending on their battery chemistry. A regular AA battery which is a an alkaline battery has a 1.5 nominal voltage charge, but when it is fresh or brand new, it will have 1.65 volts. That is the full capacity of an alkaline battery but when it reach about 1.4 volts, it will be considered dead.

In the case of rechargeable batteries with a an NiMH battery chemistry. It’s nominal voltage will be at 1.2 volts and when it is at its fully-charged state it will have a maximum charge of 1.65 volts. Rechargeable batteries like this are considered dead if they reach their 100% depth of charge, their voltage at this point will measure less than 1.2 volts.

When it comes to a lithium ion battery chemistry, a single native battery has 3.7 volts which is considered to be too much for electronic devices. This makes them dangerous for both the end consumer and the electronic equipment. AA and AAA batteries with lithium ion chemistry will not work out.

The voltage that this chemistry has far to too great that a single cell with this chemistry even has more voltage than two alkaline batteries. However, there are no electronic devices designed to use a battery like this. So, there are no manufacturers are producing AA and AAA lithium ion batteries.

Final Thoughts

By studying and looking deeper into AA batteries. The best way to say is the AA battery voltage range will be dependent on the chemistry of the cell. However, the average maximum voltage of AA batteries are set to be 1.65 volts regardless if the battery is disposable or rechargeable. When it comes end voltage, that will depend on the chemistry along with the device they are used. So the range can be dynamic and it is affected by several factors. Return to the homepage here.

Everything About AAA Battery Replacement


AAA or “Triple A” stands for American Automobile Association. It’s a service business and membership organization of several motor clubs all over North America. There are more than 58 million AAA members in Canada and the US being provided services by the organization. Services include roadside assistance, member discounts and more.

AAA Battery Replacement Services

One of the advantages of being a member of the organization is the offer of an AAA battery replacement benefit, but only to premier members. This is an extraordinary service, since all a premier member need to do in case of battery failure is to call the nearest AAA wherever he or she is, and they will replace the battery there and then, for free.

A premier member, however, can only avail of one free battery per membership per family under the AAA battery replacement benefit. This is if in a roadside service call, the test conducted by an AAA Mobile Battery Service indicates that a replacement is required. But coverage is still available for additional vehicles. The replacement battery is also limited to the typical lead-acid batteries.

For non-premier members, AAA will still safely get you back on the road but you will have to pay for the AAA battery replacement. AAA batteries are expressly designed to tolerate all kinds of climate. They come with a 6-year warranty and 3 years free AAA battery replacement. All members enjoy a minimum saving of $25 on the price of the battery.

AAA members are entitled to on the spot free testing of battery and charging system, free battery replacement and free installation services. In addition, AAA also takes care of the recycling and disposal of your old battery.

Members can also bring their battery or car to an AAA Auto Repair shop near them for battery and charging system testing, charging and replacement.

Short history of AAA

AAA was formed to address the inadequacy of roads as well as highways good enough for automobiles way back at the start of the 20th century. The organization was established in Chicago, Illinois on March 4, 1902. It started when 1,500 members from nine clubs banded together to become the initial members of the Triple A. The nine motor clubs includes the Chicago Club, Club of New Jersey, Club of America, Long Island Club, Philadelphia Club, Rhode Island Club, Club of Utica, Princeton University Club, and Grand Rapids Club.

More than 40 individual clubs, 58 million members and more than a hundred years later, Triple A’s most essential premise endures; “safe, efficient transportation is a fundamental underpinning of our society.”

Triple A’s Advocacies

Believe it or not, AAA has moral and ethical advocacies that are commendable in spite of its being a service business. It has collaborated with the government, the academe and the private sector in crafting and drafting laws and legislations that will further their cause, at the same time make the world, at least in America, a better place to live in.

Fight for better roads and highways

AAA’s initial goal was to spearhead a fight for the upgrade of roads across the nation that could safely take in vehicular traffic. Towards this end, AAA has encountered a lot of roadblocks. But AAA triumphed over most of this and can claim major successes such as the removal of state blockades to interstate travel which has made road travel safer and more convenient for everybody.

To achieve the goal of better road and highway conditions, AAA has collaborated with the government and lobbied for the drafting and passage of laws and legislations for the construction, improvement and modernization of transportation infrastructure, not only for land but including air transportation.

Traffic and pedestrian safety

Traffic as well as pedestrian safety is another advocacy of AAA. Towards this end, AAA has embarked on numerous programs such as the AAA School Safety Patrol Program which aims to keep the children safe from vehicular dangers. The organization even created a Traffic Safety division which released a teachers’ curriculum for safety education, wrote a bill for safety responsibility, and promised to continue a zealous crusade for safety in both private and public schools.

It published textbooks and instructional manuals on responsible driving that are being used not only in the academe but also in commercial driving schools. In addition, AAA also conducted training courses for driver instructors to give them the essential tools to train new drivers properly,

Roadside automotive assistance

In spite of the many services and advocacies of Triple A, most consumers view the organization primarily as a provider of emergency road services to its members; services that include AAA battery replacement, towing, tire changes, winching, automotive first aid among others. These services are taken cared of mostly by private neighborhood towing businesses contracted by an AAA club of the state.

Triple A offers roadside assistance for different types of motor vehicles, including motorcycles. In other localities, AAA even offers roadside services for bicycles. A large number of AAA motor clubs also have their own automotive fleet operation attending to large urban areas, and any calls that can no longer be served are passed on to private towing enterprises in the area. Lately, several motor clubs have started an “on the go” testing/installation battery program.

For this endeavor, AAA is instrumental in improving the skills of mechanics and auto technicians as well as help remedy the shortage of trained mechanics all over the nation. It launched programs, contests and training towards these ends.

Other advocacies and concerns of AAA that are as important are energy and environmental matters, detailed mapping of roads and highway beautification.

Summary

As you can see, AAA is not only about roadside automotive service that includes AAA battery replacement, testing and installation. The organization has evolved into an important partner of the government and the private sector in ensuring that Americans can drive safely, easily and with peace of mind across America.

It has also been instrumental in creating jobs, providing business opportunity, and educating drivers pedestrians, children and adults both on road safety and responsibility.

Guide To Testing AA Battery With Multimeter


One of the most very frustrating things for kid is when his favorite battery operated toy stop working due to dead AA batteries. It’s also similar to guy who spend his whole in the office doing completing all of his job to catch the game of his favorite team. Then as he grab the remote and press the power button, but the television refuses to switch on. Both of them are just some examples of how frustrating and annoying it is when a AA battery eventually quits on you or the device that it powers. Even to rechargeable AA batteries, situation like these may happen.

However, if your rechargeable AA batteries are charged and still unable to make the battery powered device work.. There’s a chance that your batteries are dead. If you are unsure that your AA batteries are dead, then perhaps you can follow this guide to test a AA battery with a multimeter. This is one way of knowing if your AA battery is still usable or already dead.

Understand AA and AAA Batteries and Their Chemical Structure

Like the standard battery, a rechargeable battery has an ionic paste within its cell. This chemical paste gives it its ability to take in current, store it as charge and the convert it to power its load. Non-rechargeable batteries are assumed that they are purchased with 100% charge then disposed when they are completely depleted. In the case of rechargeable AA or AAA batteries it is very difficult to tell if it is still accepting charge once they aged.

If you have a voltmeter or a multimeter it is possible to see if a AA or AAA battery can still accept charge up to its maximum capacity. To do this, you have to make sure that the battery is charged. Then you can subject it to a voltage test to see whether or not it accepted and stored the charge from the charging operation.

To use a multimeter to test your AA or AAA battery or to carry out the voltage check. You can refer to the step by step guide below.


Step 1 – Charge the AA or AAA Battery Using the Appropriate Charger

The first step in carrying out voltage check on your AA or AA battery is to charge it. Take the appropriate charger of the battery and then place it into the charger dock or compartment. Then plug in the charger into a power source to recharge the battery.

Step 2 – Prepare the Multimeter to Carry Out the Test

While the battery you will test is still charging and you are waiting for it to be fully charged. You can get the multimeter and start configuring it to right settings. Simply turn on the device and then set up to measure the direct current, and then make sure that it will measure up to the maximum amount of volts the battery can deliver.

Preferably, you want to set the multimeter to the configuration that is the same with the amount of voltage of the battery. If the device doesn’t have that option, then you can set it to higher level which is closer to the battery’s voltage. Let’s say the battery is at 3.7 volts and there’s no configuration for that amount, and the closet value which is also higher is 6 volts. Then you have to go to that settings.

Step 3 – Carrying the Actual Voltage Test with the Multimeter

Once the AA or AAA battery is fully charged, you can now proceed to the actual test with the device properly set. To do the voltage check, start by touching the metal tip of the negative probe of the device to the negative terminal if the battery. Then take the positive probe of the multimeter and touch its metal tip to the positive terminal of the battery.

To avoid confusion, keep in mind that the negative probe is the one with the black cable and the red one is the positive probe. After touching the metal tips of the multimeter to the respective terminals of the battery, you have to observe the LCD display of your multimeter to take note of the reading.

As for the result of the voltage check, what you want to see is a number slightly higher than the maximum capacity of the battery. This means that the battery took in the charge and stored it. If the reading posted a number that is significantly lower than the amount of the maximum voltage capacity of the battery. It’s bad news. It only means that the battery is hanging on for its life or maybe on the edge of its service life.

Final Thoughts

When your rechargeable batteries quit on the electronic devices that they power, it often surprises the users. Since most of these batteries are used to power the handy gadgets that we always use on our daily routine. Most of the time once when they are showing signs of failing we recharge them immediately. Make it a habit to test a AA battery with multimeter after every charging operation to keep you updated of its overall condition.
