We are building a wildlife radio tag for seals. We have the outside
case constructed, but the space for the battery is in a square shape.
We would like to use a Silver oxide coin cell battery, but instead of
it being circular, are coin cells (button cells) available in the shape
of a square or rectangle?

Thanks.

not really. round cells fit in square holes though.
