Discussion on Lithium Battery Sizes

Jul 08, 2019   Pageview:1529

Lithium batteries are also known as primary batteries. These batteries come with metallic lithium that acts as an anode. They are also referred to as lithium-metal batteries. These type of batteries stands apart from other types of batteries in terms of their high cost per unit and high charge density.

On the basis of chemical compound uses and design, these cells are capable of producing voltages from 1.5 V to 3.7 V approximately. Primary lithium batteries are different from the second one - lithium-polymer and lithium-ion that are the type of rechargeable batteries. At present, lithium is quite useful and beneficial as its ions can be easily arranged to move between the cathode and the anode. 

The “lithium battery” term is referred to a family of various different lithium-metal chemistries that compromise different types of electrolytes and cathodes, but all with metallic-lithium that acts as an anode. Lithium batteries are found in a wide range of applications. These types of batteries are available in various sizes and shapes. If you are curious to know about all sizes of lithium battery, then you have come to the right page.


In this guide, we will introduce you to more about lithium batteries, its different size and its common applications where these batteries are used. 

Lithium batteries in all sizes

Lithium batteries are non-rechargeable and that’s why it is recommended that you should never try to every charge or recharge non-rechargeable batteries. It is because if you try to do that, then it can cause a fire, rupture, or leakage. Thus, the terms “disposable”, “throw-away”, “single-use” are used for the non-rechargeable types of batteries. Also, lithium batteries provide a very long shelf life that ranges between 8 and 10 years averagely. 

All lithium cells or batteries are generally rated nominally three volts (on-load) along with approximately 3.6 volts as open circuit voltage. Battery or cell manufacturer may come up with their own part numbers for IEC standard size cells. 

The primary lithium batteries are available in a wide range of size, which includes 

· 1/2 AA

· 2/3 AA

· AA 


· C

· D

· 9V

In addition to it, these types of batteries come in various different mAh ratings i.e. the capacity of the battery and mAh is milliampere hours. Lithium batteries are used in various applications and that’s why they are quite popular all over the world. 

Lithium battery comparison of sizes and performances

Now, we move on the important part i.e. comparison of battery size and performance. This will help you to choose the right battery size for your application. 

AA Lithium battery

Lithium cells of AA size are 1.5-volt batteries. Just like every lithium chemistry battery, they are non-rechargeable. In addition to it, AA size lithium cells are a terrific alternative to the batteries called AA Alkaline and it is all because of their superlative performance. 

As lithium is known to be high-power battery chemistry and that’s why it is definitely to perform quite well as compared to standard AA Alkaline. Plus, these batteries will last five times as long as AA Alkaline batteries, even though they are pretty expensive than AA Alkaline batteries. 

There is one thing you need to keep in your mind and it is that AA lithium and AA lithium-ion batteries are different. In other words, their chemistry is quite different. Lithium-ion is a type of rechargeable battery and thus, it has rechargeable battery chemistry and they aren’t available for you to use in AA size. 

AAA lithium battery 

AAA lithium batteries are perfect alternatives to those non-rechargeable AAA alkaline batteries. AAA lithium batteries deliver 1.5 volts and they are definitely out-performing standard AAA Alkaline batteries. These types of batteries can last for eight years with no worry about the fact that they will damage or expire somehow. 

C & D size lithium battery 

As compared to AA and AAA size, C & D sizes are less common. In fact, many manufacturers have stopped making the lithium battery of size C & D. 


9 Volt lithium battery

9 Volt lithium battery is high-power and non-rechargeable batteries that provide a quite long shelf life. Non-rechargeable batteries can’t be used in smoke detectors, but the 9 Volt lithium batteries are the perfect option for smoke detectors. The 9 Volt lithium battery or cells are available in 600 mAh capacity or 1200 mAh capacity. 

Just keep in mind that the higher the capacity, the longer the lithium battery or cell will last. 

Applications of lithium battery different sizes

Lithium batteries are most widely used in electronic devices that are portable, which include 

· smartphone

· cell phone

· Laptop

· Watches 

· Camcorders 

· Digital cameras 

· Calculators 

· Personal computer BIOS 

· Thermometers

· Remote car locks 

· Communication tool or equipment

· Clocks 

· And many more 

Plus, these types of batteries are used in electric vehicles that are range from full-sized vehicles to radio-controlled toys. 

The most common type of lithium battery used in consumer applications that utilizes manganese dioxide as cathode and lithium as an anode. 

AA size lithium batteries are the perfect choice for high-drain and high-consumption products or applications. These types of batteries are widely used in GPS units, toys, cameras, flashlights, and many other applications. 

On the other hand, AAA lithium sized batteries deliver the voltage between 1.5 and 3.7 V and that’s why they are used in a lot of consumer electronic devices these days. When it comes to 9 Volt lithium batteries, they stand out from others in terms of their usage in smoke detectors. 

According to various studies, Lithium batteries or cells also prove valuable one in oceanographic applications. Even though lithium battery or cell packs are more expensive as compared to standard oceanographic packs, these batteries can hold up to 3 times the capacity of other battery packs, which include alkaline. 

The size guide of lithium battery will help you buy the right one for your application. Also, while buying lithium batteries, consider the reputable and trusted manufacturer in order to avoid purchasing the fake one.
