It’s one thing to find batteries that fit a small device, but do they provide the right amount of power and longevity for your needs?
It’s always a pain to have to replace batteries after a short period. That's why it’s advisable to find the best quality available.
AAAA batteries (commonly referred to as Quadruple-A or LR61) are smaller than the commonly used AAA and AA sizes. They are used to power small gadgets such as LED penlights, glucose meters, laser pointers, headphone amplifiers and powered computer styluses.
Despite their diminutive size, they can pack upwards of 1.5 volts of power in a slim cylindrical cell that measures 42.5 mm in length and has a diameter of 8.3 mm.
See how the AAAA alkaline battery stacks up against other variants in terms of general characteristics:
| Battery Type | Length | Diameter | Uses |
| AAAA | 42.5 mm | 8.33 mm | Laser pointers, LED pen lights, styluses, etc. |
| AAA | 44.5 mm | 10.5 mm | TV remotes, cameras, MP3 players, Bluetooth, etc. |
| AA | 49.2 mm–50.5 mm | 13.5 mm –14.5 mm | Toys, remote controls, clocks, etc. |
| C | 50 mm | 26.2 mm | Torches, toys, etc. |
| D | 61.5 mm | 33.2 mm | Large torches, transistor radios, etc. |
| F | 91mm | 33mm | High current devices |
Now that you’re more familiar with the quadruple-A battery cells, we’ll delve into the benefits of these small but useful power sources.
They Have a Great Power Output
The alkaline battery technology used in quadruple-A battery cells offers 500–600 mAh capacity, with the non-rechargeable variants having a significantly lower discharge rate.
This means that they can be used over long periods in electronic devices, especially devices that draw lower amounts of power.
A comprehensive study by Battery University found that typically, alkaline-based batteries had lower discharge currents which resulted in long lasting performance over their usage period.
AAAA alkaline batteries are generally built to last. The use of graphite, zinc and manganese in the manufacturing process gives each cell a higher density. This makes them pack significant power, even at nominal voltage.
They’re Excellent for Practical Everyday Use
Most modern electronic devices are now being manufactured with in-built rechargeable batteries.
This is great, but once the battery pack needs to be replaced, it’s harder to do. This is a hassle conveniently avoidable with AAAA alkaline batteries, which are easy to replace.
Convenience
Removable batteries have an alternative advantage over chargeable variants and can come in handy in situations where electricity is not available.
If, for instance, you’re out camping and your torch is running low on power, a quick battery replacement will have you powered up in no time.
Chargeable battery options are still unavailable for many gadgets which make the AAAA battery still relevant and practical in everyday life.
Availability
AAAA batteries may not be as easy to find since they are used for specialty products—but they’re still widely available both online and offline.
Our assortment of powerful batteries makes us the top supplier of quality replaceable cells in Australia.
AAAA Batteries are Environmentally Friendly
Modern AAAA dry cells no longer contain Mercury, which is a heavy metal that is known to harm the environment.
The packaging is done with precision and combines biodegradable cardboard and minimal plastic. This is within the environmental safety guidelines for consumer products.
The safe and environmentally-friendly blister pack holds the cells in place and prevents any unwarranted contact when packaged.
The batteries also have alternative large quantity packs which are economical and eco-friendly.
Consumers are encouraged to dispose of the batteries in the right manner to avoid unnecessary pollution of land or water resources.
The mercury-free cells also contain recyclable materials that can be used to reprocess new battery components.
They Have a Durable, Heavy-Duty Structure
Quadruple-A cells are manufactured to be able to withstand extreme environmental conditions. For instance, the average battery cell can withstand temperatures of between -18 C and 55C.
The outer casing of the batteries is designed with a special coating that decreases contact resistance for better reliability. The rugged build enables them to function in different environments and power specialty devices appropriately, even in extreme conditions.
This means that whether you live in a tropical location or a cold region, you are assured of optimal performance at all times.
Good quality batteries also have a great shelf life and can last up to 7 years in storage without losing any capacity.
The manufacturers’ quality assurance guarantees efficient energy output throughout the lifespan of the battery.
Frequently Asked Questions
What Are AAAA Batteries Used For?
AAAA batteries are mainly used for small specialty devices, including glucose meters, laser pointers, small headphone amplifiers, computer styluses, and several other small factor gadgets.
What Are the Differences Between AAAA and AAA Batteries?
An AAAA battery size is about 40% smaller—in weight and thickness—than an AAA battery despite having a similar hardware design.
Quadruple-A batteries are also used in smaller unique gadgets such as styluses and glucometers, compared to AAA that are used in common devices like remote controls and toys.
Note that despite their similarity, these two battery types are not interchangeable.
Are A23 and AAAA Batteries the Same?
These are two separate battery types. See the basic differences in the table below:
| Battery Type | Other Names | Voltage | Dimensions | Common Uses |
| AAAA | LR61 R8D425 |
1.5 V–3.7 V | Length—42.5mm Diameter— 8.33mm |
Powered computer styluses, glucometers, laser pointers, LED penlights |
| A23 | LRV08 GP23A 23AE MN21 |
1.25V1.5V | Length—28.5mm Diameter— 10.33mm |
Bluetooth headsets, garage door openers, keyless car entry systems, home security systems |
Where Can I Buy AAAA Batteries?
They are available in convenience shops and supermarkets but availability is not always guaranteed due to their speciality status. You can also purchase them online on sites such as Battery Specialists.
How Much Do AAAA Batteries Cost?
The cost ranges from $7.95 to $9.85 for an alkaline twin pack while a single rechargeable 300mAh NiMH batteries start at $6.45 each. Prices may vary from one outlet to another.
How Long Can AAAA Batteries Last When Unused?
Ideally, most alkaline batteries can comfortably last between 5 and 10 years in their packaging and still be in working condition.
However, it is advisable to store them in a cool dry place away from excessive moisture, heat or harmful corrosive substances.
