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. Former mercury cells such as the Mallory RM401, Duracell RM-401, IEC-MR1, etc. were supplanted by the alkaline Kodak KN.〔(【引用サイトリンク】title=Additional N Size Battery Sizes - BatteriesInAFlash )〕 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. Rechargeable N-Series batteries may be charged in a AA charger using a makeshift adapter (such as a small metal slug or a spring).〔(【引用サイトリンク】title=Rechargeable N Size Battery - Robot Room )〕 Some universal battery chargers (with spring-loaded contacts) are also able to charge N size batteries. Common uses for this size of battery include some small flashlights, remote control door chimes, glucose meters, small desk clocks, wireless microphones, laser pointers, small vibrators, and some vintage calculators. An N-cell battery has a similar size to the A23 battery, which has a 12V output.
