What is a UM 1 cell battery?
A D battery (D cell or IEC R20) is a size of dry cell. A D cell is cylindrical with an electrical contact at each end; the positive end has a nub or bump.
The result has mostly been the same—you are much better off buying less expensive batteries, because there is generally no measurable difference in quality or performance. (e.g., AA Alkaline Batteries made by Duracell measured against AA alkaline batteries made by Powerhouse Two).

- It depends on the power draw. An AA battery will last about 29 hours at a discharge rate of 100 mW.
The A23 battery (also known as 23A, 23AE, GP23A, V23GA, 8LR932, LRV08, 8LR23, MN21, L1028 or ANSI-1181A) is a dry cell-type battery mainly used in small electronic keychain radio devices, such as keyless vehicle entry systems, home security systems, garage door openers, and Bluetooth headsets.
- An N battery (or N cell) is a standard size of dry cell battery. 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.
