The shifter batteries last about 2 years, so about as much hassle as calculator or watch batteries. As much as I like Shimano, the SRAM wireless solution is way better. Battery maintenance is minimal and gives you redundancy. For me the single Di2 battery and additional wiring/junction boxes etc is a poor solution that is probably just a legacy of various patent battles.
