AA batteries are among the most popular kinds of Switchable power cells around today. It's what many of us usually imagine when we think of the common size and shape of the normal replaceable battery. Generally used in single-cell devices or combined into pairs to power bigger but still reasonably handy consumer electronics. AA batteries are very versatile and widely available almost all over the world. Before we proceed to calculate the weight of an AA battery, let’s take a look at the different types of AA batteries.
It's not just about getting your favorite AA battery from convenience stores. In order to make the right choice, you should know the different kinds of AA batteries and the right ones to buy when looking for these batteries to replace the old ones in your home and utility equipment. So the following are the common types of AA batteries.
Lithium AA batteries: These are a good choice for more powerful short-term use in high-drain devices like digital cameras, including low-drain equipment that needs to work for long periods of time. It can last much longer than most other types of AA in the right kinds of devices.
Rechargeable AA Batteries: These batteries are very popular these days, you will find them on sale almost everywhere that you will find non-rechargeable options. Although there are other chemistry types available, NiMH is certainly the most common choice of rechargeable AA battery you will find today.
Alkaline AA Batteries: These are the standard type, they are available in almost all kinds of places, and can be used in any relatively low-power consumer electronics.
Lithium -ion AA Batteries: This is the rechargeable type of lithium battery. They are commonly used to power drones, cell phones, vaping devices, laptops, and other high-drain devices.
How do you calculate the weight of the AA lithium battery?
When it comes to the weight of AA lithium batteries, it is important to distinguish between lithium and lithium-ion cells. The latter, usually abbreviated as "li-ion," is the widely used rechargeable version often featured in cell phones, drones, laptops, and a wide catalog of other high-drain consumer products.
The weight of an AA battery varies from 19 to 29 grams, depending on its variety. While most AA batteries are the same size, the carbon-zinc battery is much lighter than the nickel-cadmium battery. The lightest kind of AA battery is a carbon-zinc battery that weighs just 19 grams. Instead, an alkaline battery of similar size weighs 24 grams and a nickel-cadmium battery weighs 29 grams. The lithium-ion battery weighs 24 grams, as does the alkaline battery. A NiMH battery weighs 26 grams. While these kinds of batteries have similar cell size, they are also differences in the aspects of storing energy. Since some batteries include heavy metals, this is considered a dangerous waste.
To calculate the weight of an AA lithium battery, multiply Ah by 0.3 grams to determine the amount of lithium in each cell. For example, take a look at the following calculation.
3.5 x 0.3 g = 1.05 g lithium per cell
Multiply the amount of lithium in every cell by the number of cells in each battery: 1.05 grams/cell x 6 = 6.3 grams of lithium in the battery.
What is the AA lithium battery capacity?
Battery capacity (AH) is a product of the current drawn from the battery as the battery is capable of supplying the load until its voltage drops below a certain value for each cell.
Battery capacity is a measure of the charge stored by a battery and is determined by the mass of active material in the battery. Battery capacity signifies the highest amount of power that can be drawn from the battery under specific conditions. But, the actual energy storage capacities of a battery can differ significantly from the supposed rated capacity, since the capacity of the battery is highly dependent on the past history and useful life of the battery, the charging or discharging system of the battery including the temperature.
Lithium batteries offer the highest energy density of any other battery cell, which means that they store more energy than other batteries, like alkaline. Lithium batteries are only sold in AA, AAA, and 9V sizes; but, its mAh ratings outperform any other non-rechargeable battery. An AA lithium battery ranges from 2700 to 3400 mAh and will last a long time, even with heavy use.
Does a heavyweight AA lithium battery have a large current?
The current of a battery is like the speed range of a vehicle. If your vehicle has a range of approximately 300 miles, you can travel 30 miles per hour for ten hours or 60 miles per hour for five hours. Your effectiveness will get worse with speed, therefore when you run 60 mph; you may run out of gas after just four hours, within the 240-mile range. This means that under a given technology, a battery with double capacity can supply twice the maximum current. Batteries are often specified with a discharge rate in terms of C, where C is the battery capacity divided by hours.
AA batteries are common in portable electronic devices. An AA battery consists of a single electrochemical cell which can be a disposable battery or a rechargeable battery. Numerous different chemistries are used in their construction. The precise terminal voltage, capacity, and discharge rates depend on the cell chemistry. But, devices designed for AA batteries generally take just 1.2 - 1.5 volts, unless specified by the producer. AA batteries with high capacity store more charge and can run your devices for a longer period. A lithium battery can cost 5 times more than an alkaline battery, but it will last 8-10 times longer in operation, with the same lifespan when not in use
For many electronic devices, you can't live without; lithium battery technology has proven to be the worlds longest in AA and AAA batteries in high-tech gadgets, providing long-lasting power to keep up with the latest high-tech, energy-hungry gadgets like photo flash units, digital cameras, and portable GPS devices, and many others.
In conclusion, keep in mind that AA lithium batteries provide longer life, higher capacity, and significantly less weight. They have a tendency to get a higher voltage capacity, energy density, including a lower discharge rate than other batteries. This improves energy efficiency as a single cell has a longer charge than any other type of battery.
