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 nub or bump on the top. The battery has a length of 30.2 mm and a diameter of 12.0 mm, and is approximately three-fifths the length of a AA battery.
A zinc-carbon battery in this type is designated as R1 by IEC standards; likewise, an alkaline battery in this type is designated as LR1. ANSI designates this battery as 910A and 910D for alkaline and zinc-carbon chemistries, respectively. Energizer calls this type E90.
Mercury batteries of the same dimensions are no longer manufactured because of their toxicity. If your requirement is to replace a Mallory RM401, Duracell RM-401, IEC-MR1, NEDA 117M, 910M, Eveready E401, E401N, E401 N, Energizer EP401, EP401E, NR1, R401, or RP401, you may consider using the Alkaline Kodak KN in its place.
Rechargeable N-size batteries are also available, in nickel-cadmium (KR1) and nickel-metal hydride (HR1) chemistries. However, these are far less common than other rechargeable sizes, and may be charged in a AA charger using a makeshift adapter (such as a small metal slug or a spring).
There are newer chargers that work well for charging the N size rechargeable batteries now. A universal battery charger will charge several common size batteries and chemistries. This includes batteries like 1/2AA, 1/3AA, 1/3AAA, 2/3A, 2/3AA, 2/3AAA, 4/3A, 4/5A, 4/5AA, 5/4AAA, A, AA, AAA, N Series
Common uses for this size of battery include some small flashlights, remote control door chimes, glucose meters, small desk clocks, wireless microphones, and laser pointers. This battery size must also not be confused with a similar-sized A23 battery, which is 12 volts and not 1.5 volts.
