I use rechargeables for most of my sensors. [RCR2s](https://community.smartthings.com/t/deals-batteries-for-things-mostly-u-s/46118/18) for the Iris v2 contact and motion (most of the motion sensors I keep on non-rechargables). I’m still deploying the RCR2s I got back then, as the sensors I [got in 2020](https://community.smartthings.com/t/recommendation-for-contact-sensors-in-bulk/192405) are just now using up their original CR2s, after almost 4 years. I only get 18 months on the RCR2s.

I keep a spreadsheet of battery replacement dates. I’ve changed batteries in 31 devices so far this year.
