Not all are, some are square
With the same load current the AA will last longer that the AAA. This is due to the physical size of the cells. A C cell will last longer that a AA and a D cell will last longer that a C cell. In dry cells as the cells get larger the amp/hours increase.
Energizer (and many other battery companies) sell two kinds of "lithium" batteries: "Lithium Photo/Coin", Li-Mn, "CR" button cells, such as the CR2032, provide about 3 V. "Lithium cylindrical", "Lithium-iron", "Li/Fe", which comes in AA and AAA, are about 1.5 V, and also comes as those rectangular 9V batteries, which... of course... are about 9V.
Dry cells typically have two terminals: a positive terminal (anode) and a negative terminal (cathode). The positive terminal is usually marked with a "+" sign and is often the central rod in cylindrical batteries, while the negative terminal is the outer casing. These terminals allow for the flow of electric current when the dry cell is connected in a circuit. Common examples of dry cells include alkaline batteries and zinc-carbon batteries.

Cylindrical objects are typically measured using calipers, which can provide precise measurements of diameter and length. A tape measure can also be used for larger cylindrical items, while micrometers offer high accuracy for smaller diameters. Additionally, a laser distance meter can measure the length of longer cylindrical objects more efficiently.
because it have a lots of energy inside it and wouldn't explorer
the negative pole of cylindrical batteries is the smooth end.
CR lithium batteries are cylindrical in shape and typically used in watches, calculators, and some small electronics. DL lithium batteries are coin-shaped and commonly used in medical devices, cameras, and other portable electronics. The main difference is their size and shape, with CR batteries being cylindrical and DL batteries being coin-shaped.
The flashlight shape is always in tube body, which is easier to held by hand and put in batteries.
Flashlight batteries are typically smaller, cylindrical batteries designed for portable use, providing low voltage and current for short periods. In contrast, car batteries are larger, lead-acid batteries designed to deliver high current to start the engine and power electrical systems in a vehicle. Car batteries can also be recharged multiple times, while many flashlight batteries are single-use or rechargeable with different voltage specifications. Additionally, car batteries have a much higher capacity and are built to withstand extreme temperatures and vibrations.

The most commercial use of the cr123 lithium batteries are digital cameras. But the batteries are primarily used in very high end flashlights where the lasting brightness of the flashlight is very important to the user.

AA batteries are typically alkaline or rechargeable NiMH cells with a nominal voltage of 1.5V and a cylindrical shape measuring about 14.5mm in diameter and 50.5mm in length. In contrast, 18650 batteries are lithium-ion cells with a nominal voltage of 3.7V, measuring 18mm in diameter and 65mm in length. The higher energy density and rechargeable nature of 18650 batteries make them suitable for high-drain devices, while AA batteries are commonly used in everyday household devices. Additionally, 18650 batteries often require specialized chargers and safety precautions due to their higher energy capacity.
A 3AA battery typically refers to a battery configuration consisting of three AA-sized batteries connected in series. AA batteries are cylindrical, commonly used in household devices, and can be alkaline, rechargeable (NiMH or NiCd), or lithium. The combined voltage of three AA batteries is 4.5 volts (1.5 volts each). This configuration is often used in devices that require higher power or longer usage times.
