The different battery types follow along with the various functions these serve in giving you reliable power solutions for all applications.



Here are the “Big 5” battery sizes that you can buy online or even offline in the Australian market. These are not actually the biggest in size but in popularity or high market demand.

Different battery sizes, Big 5 batteries 


The AA batteries are also called Double A batteries. AA is one of the Big 5 in the battery market. The AA battery comes with different battery chemistries such as AlkalineLithiumLithium-ionNiCad, and NiMHCarbon Zinc or other Lithium-based ones. Battery dimensions and characteristics slightly vary based on battery chemistry. AA battery comes as both primary and rechargeable cells. These are commonly used in almost all portable devices such as remote controls, toys, and game controllers, calculators, clocks, hand sanitisers, and other gadgets. These come as either disposable or rechargeable batteries.

Price Range

- Primary AA: $0.97 - $30 approx. (depending on brand and package options)

- Rechargeable AA - Price starts at approximately $5.84/piece

Procell INTENSE Power AA, Procell Alkaline AA batteries


The AAA batteries are smaller than AA batteries. These are also fondly called as the Triple-A batteries. Like the AA batteries, Triple-A cells have disposable and rechargeable variants. Like Double-A batteries, Triple-A dry cells usually power most portable household items such as clocks, cordless phones, calculators, toys, TV remotes, medical batteries, and other common household devices that require smaller cells. These are also primary and rechargeable batteries. Alkaline and Lithium make up the primary variants while NiCad, NiMH, Lithium-ion, and other chemistries make up the AAA rechargeable batteries. Some brands have designed AAA batteries to be used specifically for high drain devices such as the Procell INTENSE Power AAA batteries. On the other hand, Procell Alkaline AAA batteries are used for general purposes and low drain devices. Other brands may have other battery applications and engineering for the different types of applications used by the various industries and sectors, as in the case of EnergizerDuracellAnsmannEneloopFujitsuPanasonicCamelion, and many more.

Price Range

- Primary AAA: $3.45 - $71.88 approx. (depending on brand and package options)

Talking about battery types, these are primary or disposable batteries and rechargeable batteries. Primary batteries are usually made of AlkalineLithium, and other related battery chemistries. When it comes to rechargeable batteries, there are rechargeable Alkaline, Lithium ion, Nickel Cadmium (NiCad), Nickel Metal Hydride (NiMH), Lead Acid, Lithium Polymer, Lead Acid, and other Lithium variants.

battery sizes


Primary or non-rechargeable batteries are usually Lithium and Alkaline batteries. Alkaline batteries have a power density of 100 Wh/Kg. The advantages of using an Alkaline battery are almost endless. These include having more cycle life and shelf life, low leakage, high efficiency, and greater compatibility with portable devices due to their small size. Another advantage of using an alkaline battery is that it has a low internal resistance resulting in less discharge in the idle state. The only disadvantage of alkaline batteries is that it is a bit costly compared to lithium batteries.

Knowing the right rechargeable battery for your device also introduces you to know the proper battery size for battery replacements in case you need to do so. Rechargeable batteries are made up of such chemistries as LithiumLithium ionNiCadNiMHLiFEPO4Lithium Thionyl Chloride Silver Oxide Zinc AirCarbon ZincAGM/SLA, and other options. These rechargeable batteries are available in almost any battery size. Every battery chemistry has its own advantages and disadvantages. For instance, NiMH batteries may have their own features that are not in NiCad or the rechargeable alkaline batteries. Lead batteries, on the other hand, are bigger batteries that may not have other characteristics or advantages that can be found in smaller batteries. This is the reason why you have to understand the different sizes, types, chemistries, and other related factors to help you find the precise batteries you need for every type of application and device you wish to optimize.


These battery chemistries have different standard sizes. AAAAACD9Vbutton cellscar batteries, and other specialty cells have different rechargeable battery options and brands to choose from.
