But the most significant difference is size because batteries are called AA & AAA because of their size and dimension. AA doesn’t stand for anything. It is simply an identifier for a battery of given dimensions and nominal voltage. AAA batteries are smaller in size as compared to AA.
Why is it called AA batteries?
As batteries had only gotten larger previously to produce more juice for larger or hungrier portable devices, there was nothing ‘smaller’ than A. Thus, AA was designated. By 1959, AAA was added to the list of specifications.
Why do batteries have different labels such as AAA C or D?
Originally Answered: How come there are AA, AAA, C, & D batteries, but not B? A B and C batteries were names given to the types used in early portable valve radios before the advent of transistors. Others have since been added to the repertoire and some names have been changed.
Why is it called triple A battery?
Probably the name originated from the original ‘A’ type battery standard from ANSI and IEC.At that time A referred for the battery based on zinc and ammonium chloride. And after that we had similar dry cells having reduced size named as AA and AAA. Nowadays we even AAAA battery which is the smallest of the four.
Why are there no B batteries?
Since then, the ANSI standard for batteries has been revised numerous times as battery technology has evolved. Why it appears there is no B (or A, F, etc.) anymore is simply because those particular battery sizes never really caught on commercially, at least on the consumer end of things.
What does the A stand for in battery?
Answer has 6 votes. Currently voted the best answer. 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.
What does INR mean on A battery?

What does SAE stand for in batteries?
This is the starting test according to the SAE (Society of Automotive Engineers). The test specifies that the battery at a temperature of –18°C will deliver a current equal to the Cold Cranking Amps for 30 seconds with the voltage staying above 7.2 volts (3.6 volts for a 6 volt battery).
What does EN stand for on A car battery?
Exact Fit European Norm (EN) Design Batteries. Today’s automotive manufacturers build vehicles that demand battery replacements that meet specific Amp Hour (AH), Cold Cranking Amps (CCA) and Reserve Capacity (RC) ratings, cover designs, hold-down requirements, and critical venting systems.
What are U2 batteries now called?
Cylindrical batteries
| Names | ||
|---|---|---|
| Most common | Other common | ANSI |

Why are there no C batteries?
In 1924, industry and government representatives met again to figure out a naming system for all those cells and batteries they had just standardized. They decided to base it around the alphabet, dubbing the smallest cells and single-cell batteries “A” and went from there to B, C and D. There was also a “No.
Does a bigger battery mean more voltage?
The size of the battery has no impact on the voltage output. For every chemical system, a battery puts out a specific voltage. So for higher voltage, a number of cells are put together in series.
What’s the difference between AA and AAA batteries?
AA and AAA are battery designations that are used to indicate the size and potential charge capacity of certain batteries. 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.
What type of batteries are AA?
Technical Specifications Of The AA Battery (Alkaline, Lithium, and Carbon Zinc)
| Alkaline AA Battery Nominal Voltage | 1.50 Volts |
|---|---|
| Operating Temperature | 0°C – 60°C |
| Diameter | 14.5mm |
| Height | 50.5mm |
| Chemistry | Alkaline |
What is AA vs AAA battery?
The main difference between AA and AAA batteries is in physical dimensions. AA batteries feature physical dimensions of 14.5 x 50.5 mm, while AAA batteries feature physical dimensions of 10.5 x 44.5 mm.
Is there a AAAA battery?
AAAA Batteries are small batteries that are cylindrical in shape. Also called LR61 or MN2500 batteries, AAAA batteries are commonly used in electrical devices like LED penlights and Bluetooth headsets to name a few.
Do Single A batteries exist?
There’re “A” size batteries available though aren’t so common. A batteries did and do exist. They were used in early phones, etc. They are still available, but not common in stores within the US.
Why do batteries have letters?
The letters and numbers in the code indicate the number of cells, cell chemistry, shape, dimensions, the number of parallel paths in the assembled battery and any modifying letters deemed necessary. A multi-section battery (two or more voltages from the same package) will have a multi-section designation.
What does 20Ah mean?
If a battery is rated at 20Ah capacity at 20HR, it means that the battery can discharge 1 Amp per hour over that 20 hour period. A High Rate Battery will typically be rated at 10HR or less. So if a High Rate Battery that is 20Ah capacity at a 10HR, it would be able to discharge 2 Amps per hour over a 10 hour period.
Is AAA lithium battery?
Consumer-sized batteries (up to 2 grams of lithium per battery) may be carried. This includes all the typical non-rechargeable lithium batteries used in cameras (AA, AAA, 123, CR123A, CR1, CR2, CRV3, CR22, 2CR5, etc.) as well as the flat round lithium button cells.
When was the AA battery invented?
Introduced in 1907 by The American Ever Ready Company, the AA battery size was standardized by the American National Standards Institute (ANSI) in 1947, but it had been in use in flashlights and electrical novelties before formal standardization.
