We are building a wildlife radio tag for seals. We have the outside

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.

can you not fill the whole length of the tag fastener
with small button cells? Embedded in the plastic.
