I wanted to share my experience with upgrading the battery life of my Wyze presence sensors. After being frustrated with the short battery life of the default CR2032 battery, I decided to take matters into my own hands. Here’s what I did:
The Problem:
My Wyze presence sensors were only lasting about 3 months on a single CR2032 battery. While this is decent, I knew I could do better. Since a CR2032 is 3v and ~240mAh, I figured I could increase the capacity significantly by using two AA batteries in series to get 3v and 1900mAh capacity. This is about 8x the capacity of a single CR2032 battery!
The Solution:
I purchased a few battery cases with leads and project boxes. I took the sensor out of its case, peeled off the protective layer, and carefully separated the plastic shell. I then soldered the positive and negative terminals of the two AA batteries to match the polarity of the original battery setup.
The Results:
I housed the new battery setup in a small project box and installed it back into the sensor. The sensor has been running for over 6 months now, and it’s still going strong! This upgrade has drastically reduced the need for frequent battery changes and has saved me a lot of time and hassle.
Tips for Others:
- Make sure to test the polarity of your battery setup before soldering.
- Use a project box that fits snugly to keep everything in place.
- Consider using hot glue to secure the battery leads if needed.
I’m really happy with how this upgrade turned out and would recommend it to anyone looking to extend the battery life of their Wyze presence sensors. If you have any questions or need help with the process, feel free to reach out!
