... and this conversation reminds me that it's been a full 1.5 years since I've installed a battery in my eGR right shifter. I've never sweated this, because my assumption is that as much as I use the right brifter, the left brifter MUST consume less power. Right? My backup plan has always been to pull out my phone and use the app to switch brifters. Absolute worst case, use the app to shift if/when necessary to get home.
Man! You got me thinking about the battery level of my first eR9 set that I installed two years ago now. It's been ridden over 10.000km at this point. It's not dead yet, but the strategy you have is exactly what I had in mind.
