Button cell/watch battery cross reference

Button cells are available in the same size under different manufacturer specific names. 1.5V cells are available as alkaline batteries or as more expensive but more durable silver oxide batteries. The alkaline and silver oxide batteries used to have different names. E.g LR44 was an alkaline battery and SR44 was a silver oxide battery of the same size. Many manufacturers started however to print multiple names onto their battery packages and use them now interchangeably. Thus if you want to know if a given battery is Silver Oxide or Alkaline then you have to look for those words on the package. You can not trust the name alone.

The varta battery number starts with a "v". It is in most cases the most commonly used name and I use it as index to the below table.

If you have an old watch with no battery in it then measure the size (height and diameter) of the battery holder to find a matching battery.

The most common watch batteries are V371 (quality men's watches) and V377 (quality lady's watches and most cheap made in china movements).

LR44/V357 is a very common pocket calculator battery.

CR2032 is the most common lithium button cell (3V) and is not part of this cross reference. Lithium button cells are normally named after their size (CR2032=20mm x 3.2mm) and all manufacturers use the same name or at least the same numbers prefixed by different letters. A cross reference is therefore not required for lithium buttons cells.

Note that Bulova got it all messed up. Most manufacturers use the same numbers and add just some letters to the name. Bulova battery numbers are however completely off. A bulova-317 has nothing to do with a V317. It's a V391.
