Summary

CR2450 battery eliminator inspired by CR2032 battery eliminator by notagenius to replace battery in Sonoff Zigbee Temperature Sensor SNZB-02.

Needs no supports when printed upside-down.

Insert two wires: One through the vertical holes for ground and one through the horizontal hole and around the outside for 3V. Connect to the power source of your choice. 0.8mm² (1mm diameter) wire works best.

I use this in my Sonoff temperature sensor battery hack.

2024-04-03: Added a version 2 that works better with 0.8mm² wire (you don't need the older version if the new one works for you).
