Watch Battery Cross Reference Table
The Watch Battery Cross Reference Table below gives all Watch Battery sizes and their equivalent replacement watch battery reference
numbers as used by various different watch battery manufacturers.
The Watch Battery Cross Reference table can be sorted by watch battery size,
either by selecting the watch battery diameter, or the watch battery thickness
(or height). This will give you an idea of which watch battery to choose if
you do not have a watch battery cross reference number to match the battery against.
Sorting by watch battery diameter will also present the results with the watch battery heights sorted too. Conversely if you sort by watch battery
height the result will show the watch battery diameters also sorted in ascending order of watch battery diameter.
Note, that the lithium watch batteries, or button cells, are 3 volts, not 1.5 volts
and cannot be substituted for a 1.5 volt silver oxide watch battery or alkaline watch battery,
even if the sizes are comparable.
Mercury watch batteries are no longer manufactured so your only alternative is to use a silver oxide watch battery
of the same size. You should check that your application will not be affected by the slight increase in
battery voltage which will result in using a silver oxide watch battery instead of the mercury watch battery.
For further information about watch batteries; their chemistry, numbering, watch battery prefixes and watch battery suffixes read our All About Watch Batteries write up.
The battery numbers in blue text are links to more information on the particular battery and will take you to a
page where you will be able to order the battery.

If you are replacing a National GR927 battery in a Casio calculator please note that your calculator handbook is likely to say that
this is a lithium battery. The handbook is wrong! The replacement for the National GR927 is the 399 silver oxide battery and not
the CR927 3V lithium battery. This mistake in the handbook appears across several different models of Casio solar calculators.
Note: CR/BR (Lithium) battery types are 3.0 Volts.
