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. . The N-cell battery was designed by and was part of a series of smaller batteries including the Z battery () and the Number 7 battery (). A . • . • [pdf]
The AAA battery (or triple-A battery) is a standard size of dry cell battery. One or more AAA batteries are commonly used in low-drain portable electronic devices.
3. Rechargeable Batteries (NiMH) AAA batteries are known by various designations across different standards: Maintenance-free sealed AGM battery, compatible with various motorcycles and powersports vehicles. Sealed AGM battery designed for ATVs, UTVs, and motorcycles, offering reliable performance.

AA batteries (14.5 x 50.5 mm) are larger than N-sized batteries. As a result of the larger size, they aren’t directly compatible. However, some devices have a smaller holder in the battery compartment that allows them to work with N-sized cells.
In China, they are called #7 batteries, the name originating from the Burgess Battery Company designating his AAA batteries "Number 7". [citation needed] 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).
