We're working on an updated version of our soil sensor, and thinking of making a version that has a coin cell battery on the back. However, we can't use the common 'retainer' style of CR2032 coin cell holder because we will have traces on the back that would make routing hard.

Let's search for a battery holder that comes on tape - so we can pick and place it - but is SMT and is a proper holder that has small positive and negative pads. We want a slim and unobtrusive style if possible, and low cost so we can keep our BOM minimal.
