10.5 mm.
An AAA battery is a single cell that 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).
Are all AAA batteries the same size?
At first, AAA and 18650 batteries don’t have much in common – AAA batteries are cylindrical batteries 10.5 mm (0.41 inch) in diameter and 44.5 mm (1.75 inches) in length, while 18650 batteries are cylindrical batteries 18.6 mm (0.73 inches) in diameter and 65.2 mm (2.56 inch) in length.
What is the size difference between AA and AAA batteries?
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.
What is a size a battery?
AAA batteries, like AA batteries, also measure at 1.5V, but generate less energy due to their smaller size. These batteries are used primarily in small devices that don’t require a lot of energy, like kitchen timers. The batteries will last a long time, while still accomplishing their purpose.
How big is AAA battery?
An AA cell measures 49.2–50.5 mm (1.94–1.99 in) in length, including the button terminal—and 13.5–14.5 mm (0.53–0.57 in) in diameter.
What is the mAH of a AAA battery?
FAQ

What is the diameter of AD battery?
1.3 inches
The standard size of D battery is: Diameter: 33.2 mm/1.3 inches.
Why are AAA batteries smaller than AA?
This is because they are basically just a single cell. 9 Volt batteries utilize six cells in a series to come up with the higher voltage. The smaller size of the AAA batteries means that there is a smaller amount of electrochemical material, which contains that electric charge.
Can you use double A batteries instead of Triple A?
AA and AAA batteries are both 1.5V nominal (for disposable) and 1.2V nominal for rechargeable (usually NiMHs.) As long as the current draw doesn’t exceed the AAA’s ability, you can use a AAA in place of a AA by bridging the gap (may need some padding around it as well to keep it aligned.)
Is there a battery smaller than AAA?
An A23 battery is cylindrical and somewhat shorter than a AAA battery, measuring 28.5 mm long and 10.3 mm in diameter, with a typical weight of 8 grams. An A23 battery is an 8-cell device with a nominal voltage of 12 V.
What is a 1.5 V AAA battery?
What is a 1.5v Battery? A classic nominal voltage, most AA, AAA, C, & D cells are 1.5 volts, and many household and handheld devices have been built to use that voltage. The first zinc-carbon dry cells naturally produced 1.5 volts of energy, and has remained the standard ever since.
Where do you find battery size?
First way to determine battery group size is to look for specifications in the vehicle manual. Battery specifications are generally present in the manual and are easy to get. Note down the specification written in letters and numbers. The second way is to look directly on your battery (See Figure below).
How is battery size measured?
Battery capacity is measured in milliamps × hours (mAH). For example, if a battery has 250 mAH capacity and provides 2 mA average current to a load, in theory, the battery will last 125 hours.
Is a 1.5 V battery the same as a AA?
A 1.5-volt battery is the same size as AA batteries, but is rated for lower voltage to suit a device with a lighter power requirement such as a flashlight. Just be sure not to mix the two up—because they’re exactly the same battery.
Can you use 1.2 V batteries instead of 1.5 V?
Q : Can I use 1.2 V rechargeable batteries in devices that usually take 1.5 V throw away batteries? Yes, most definitely. Using 1.2 V rechargeable batteries will have no effect on the use of the equipment. In fact an alkaline battery only benefits from 1.5 V voltage at the beginning of its discharge.
