An 18650 battery [1] or 1865 cell [2] is a cylindrical lithium-ion battery common in electronic devices. The batteries measure 18 mm (0.71 in) in diameter by 65 mm (2.56 in) in length, giving them the name 18650. [3] The battery comes in many nominal voltages depending on the specific chemistry used.
An N battery (or N cell) is a standard size of dry-cell battery. An N battery is cylindrical with electrical contacts on each end; the positive end has a bump on the top. The battery has a length of 30.2 mm (1.19 in) and a diameter of 12.0 mm (0.47 in), and is approximately three-fifths the length of a AA battery.
An AA-sized alkaline battery might have an effective capacity of 3000 mAh at low drain, but at a load of 1 ampere, which is common for digital cameras, the capacity could be as little as 700 mAh. [12] The voltage of the battery declines steadily during use, so the total usable capacity depends on the cutoff voltage of the application.

A lantern battery is a rectangular battery, typically an alkaline or zinc–carbon primary battery, used primarily in flashlights or lanterns. Lantern batteries are physically larger and consequently offer higher capacity than the more common flashlight batteries. Lantern batteries comprise multiple cells inside a housing.
The common CR2032 battery is 20 mm diameter and 3.2 mm thick, where the first two digits is the diameter and the last two digits are thickness. A CR2025 is the same 20 mm diameter but 2.5 mm thick. The heavy electrical demands of many of these devices make lithium batteries a particularly attractive option.
