The most significant difference between the two, is their size. AAA batteries are smaller compared to AA. This is important, as battery operated devices often use only one specific size. AA and AAA batteries carry the same amount of voltage, as do bigger batteries, like the D type.
Likewise, what does the A stand for in AAA batteries?
An AAA or triple-A battery is a standard size of dry cell battery commonly used in low-drain portable electronic devices. A triple-A battery is a single cell and measures 10.5 mm (0.41 in) in diameter and 44.5 mm (1.75 in) in length, including the positive terminal button, which is a minimum 0.8 mm (0.031 in).
What is an AA lr6 battery?
It can be Zinc Carbon or Alkaline or NiMH or anything else. However when you see LR6 the L confirms that it is an Alkaline cell and R usually mean round which tells us the shape of the cell and 6 happens to be in the IEC name of any AA cell.
The answer isn't as obvious as you would think. While the minor league system in baseball is generally hierarchical — Low A is better than rookie ball, High A is better than Low A, AA is better than High A — that hierarchy splits at AA / AAA rather than continuing in sequence.
Convert AAA Batteries Into AA Batteries with Tin Foil. If you run out of a charge on a pair of AA batteries but have some AAAs laying around, reddit user Its738PM suggests using a strip of tin foil to convert the AAA battery into a AA battery. To get this to work, all you need is a AAA battery and some tin foil.
After the testing was completed the following results were recorded: The Duracell battery lasted the longest, 101 hours and 20 minutes; Energizer battery, second, 99 hours and 17 minutes; Eveready battery, third, 28 hours and 30 minutes, and last but not least was the BA 30 batteries, 25 hours ad 58 minutes.
In brief: No, the 18650 cells can not be used in place of standard AA batteries, rechargeable or otherwise: The nominal voltage of the 18650 is significantly different from the 1.5x3=4.5V of the three AA cells, assuming those are connected in series.
The AAAA battery (usually read as quadruple-A) is 42.5 mm long and 8.3 mm in diameter. The alkaline cell weighs around 6.5 g and produces 1.5 V. This size battery is also classified as R8D425 (IEC) and 25 (ANSI/NEDA).

Cylindrical batteries. These are round batteries with height longer than their diameter. In zinc-carbon or alkaline types they produce around 1.5V per cell when fresh.
Types of Batteries
- NICKEL CADMIUM BATTERIES. The active components of a rechargeable NiCd battery in the charged state consist of nickel hydroxide (NiOOH) in the positive electrode and cadmium (Cd) in the negative electrode.
- NICKEL METAL HYDRIDE BATTERIES.
- LITHIUM ION BATTERIES.
- SMALL SEALED LEAD ACID BATTERIES.
The letters on a battery give the size, in height and width, of the battery. AA means “50.5mm x 14.5mm.” The later the letter the larger the battery. "D" is larger than "C", etc. "A" is larger than "AA" is larger than "AAA".

Rechargables like NiCad or NiMH have freshly charged voltages of about 1.4 but quickly settle to 1.2 to 1.25 Volts for most of the discharge curve. Single use batteries like Alkalines or Carbon zinc (so called heavy-duty batteries) have initial output of 1.5–1.6 volts and fall gradually to 1.0 to 1.3 at end of life.
A small AAA cell might put out 1-2 Amps but its voltage is compromised by the internal resistance so it might not be usuable. It's not suitable for outputting 2 amps continuously much like you would not drive a normal car 120mph continuously even though it can do it.
An electric battery is a device consisting of one or more electrochemical cells with external connections provided to power electrical devices such as flashlights, smartphones, and electric cars. When a battery is supplying electric power, its positive terminal is the cathode and its negative terminal is the anode.
A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. LIBs are also growing in popularity for military, battery electric vehicle and aerospace applications.
Take a single-use alkaline battery for instance. These are the non-rechargeable type batteries that come in AAA, AA, C, D, 9 volt and various button cell sizes. On average, 25% of the battery is made up of steel. 60% of the battery is made up of a combination of materials like zinc, manganese and potassium.
The 'C' battery (or R14 battery) is a standard size of dry cell battery typically used in medium-drain applications such as toys, flashlights, and musical instruments.
Fully charged automotive batteries should measure at 12.6 volts or above. When the engine is running, this measurement should be 13.7 to 14.7 volts. If you don't have a multimeter to tell you the voltage of your battery, you can do a test of your electrical system by starting the car and turning on the headlights.
The 18650 (18mm by 65mm) battery is a size classification of lithium-ion batteries. If you have ever held one in your hand, you probably noticed it is the same shape, but a bit larger than a AA battery. AA batteries by comparison are sometimes called 14500 batteries, because they have a 14mm diameter and 50mm height.
You're right, C and D batteries both are 1.5 volts. Actually, AA and AAA are also 1.5 volts. If they're the same voltage, why not just use all AAA batteries and make things lighter and smaller. But there is a big difference between them all.
AAA, AA, C, D batteries all are rated at 1.5 volts but besides the difference in physical size there is a big difference between them all. In an electrical circuit or device, there are two really important things:voltageandcurrent.
