AA Batteries

AA batteries are small in size and part of flashlights, toys, and remote controls. The dimensions of the battery are 50.5 mm, and the diameter is 14.5 mm, and the voltage rating is 1.5 volts. AA batteries come with alkaline and lithium chemistry and also have rechargeable nickel-metal hydride (NiMH).

The basic differences of AA batteries from AAA or AAAA batteries are capacity and size. AA batteries come in larger sizes and capacities and are best for devices where high power is needed and use more current.

AAA Batteries

AAA batteries are smaller compared to AA batteries, with dimensions of 44.5mm in length and a diameter of 10.5mm. It also has a rating of 1.5 volts. The chemistry used in batteries is lithium, alkaline, and rechargeable NiMH.

AAA batteries are part of devices that use low power, like remote controls. wireless keyboards.

As compared to other batteries, AAA has less capacity and a small size and is best for features where low power is needed. But it is higher cost than AA and lower cost as compared to AAAA.

AAAA Batteries

The AAAA battery is small compared to the other two batteries and has dimensions of 42.5 mm in length and 8.3 mm in diameter. The rating of the battery is 1.5 volts and has alkaline and lithium chemistry. AAAA battery used for laser printers, medical devices.

AAAA batteries are small in size and low in capacity and are best for devices that need low power or use low current. It is not easily gotten and has a higher cost than AA and AAA batteries.

AAAA Battery Equivalent?

Based on manufacturers and brands, there are different batteries used as equivalents of AAAA batteries.

The commonly used AAAA battery replacements are MN2500, E96, LR8D425, and MX2500. These batteries are commonly used as direct replacements for AAAA batteries.

These equivalent batteries have the same size and dimensions as AAAA batteries but are not used as direct or accurate replacements since they have different chemistry and working features.

AAAA Batteries Applications

Non-Rechargeable AAAA Batteries

The commonly used non-rechargeable AAAA battery is an alkaline AAAA battery with a nominal voltage of 1.5 volts and a capacity range of 400-600 mAh. The other common uses of non-rechargeable features are

Battery Datasheet	Capacity	Temperature Annual Self-Discharge Rate
Duracell MX2500	300mAh to 500mAh	-20°C to 54°C
Energizer E96	680mAh down	18°C to 55°C
GP AAAA	525mAh	–

Zinc-carbon batteries are low cost compared to alkaline AAA batteries, but they have stable voltage, larger capacity, and longer working life, which is preferred when creating batteries.

Rechargeable AAAA Batteries

Rechargeable AAAA batteries have nickel cadmium (NiCd), lithium-ion batteries, and nickel metal hydride. Nickel Cadmium (NiCd) AAAA batteries are rare for common uses since they have cadmium, which is a toxic and heavy metal.

NiCd batteries have low inner impedance and have features for providing larger current. With that, they also have a larger self-discharge rate and come with a strong memory effect, are compatible with fewer charging and discharging cycles as compared to NiMH batteries, and have a low capacity.

NiCd and NiMH batteries come with 1.2 volts, and some devices that are used for 1.5V zinc carbon or alkaline batteries work well for 1.2-volt NiCd and NiMH batteries.

The real capacity is based on discharge conditions and battery working life, which is less as compared to NiMH batteries.

Nickel Metal Hydride (NiMH) batteries are also compatible with larger charging/discharging cycles as compared to NiCD batteries and do not have a memory effect.

AAAA Battery vs. 4LR61 6V Battery

The 4LR61 battery is six volts with dimensions of 48.5 x 35.6 x 9.18 mm, and its design helps to use it in the battery proper room in a single direction. 4LR61 batteries come with 4 LR61 batteries in a series combination.

The LR61 battery is small compared to the AAAA battery, and in some devices, there is a plastic battery holder that has 4 AAAA (8.3 x 42.5 mm) batteries.

Uses of AAAA Batteries

AAAA batteries are small and thin compared to AA and AAA batteries and are used for different devices.

Non-rechargeable alkaline AAAA batteries are best to use for longer working life and have a stable nature and are best for low-drain uses such as laser pointers, LED penlights, and remote control devices.

Rechargeable lithium AAAA batteries are a low-cost option and best for devices where high energy is needed and are commonly used in medical devices, cameras, and high-end audio devices.
