I have a Ruuvi Pro I use in my sauna. The time has come for a replacement battery. The problem is I live in North America and the website does not ship the batteries outside Finland. If you look at the website, it states this battery has been customized due to the temperature ranges extendible given the circumstances of utilization.
My question is has anybody used a regular 2477 battery with success in a similar situation I seem to have no alternative other than buying a brand new device every time I want a new battery which is ridiculous.
