There are a few other things that surprise me on occasion, my kitchen immersion thermometer might use a 2032, I do not remember, etc. I have a couple wired bike computers, I get several years per battery on those, each computer only takes one 2032.
The main culprit is the wireless bike computers.
You must mean
inexpensive wireless bike computers. My wireless bike computers have never needed battery replacement. And the sensors at most go at least 2 years and more with no need to replace their batteries. Except my PM I got a couple years ago did need a battery replacement at 1 year and that is the particular thing I experienced the issue with the bad Duracell CR2032's and had to replace it several times till I realized the entire blister pack of batteries all had too little voltage remaining in them.
