The gravel bike has four batteries. SRAM AXS derailer, both shifters, and a Power2Max power meter. AXS battery gives me plenty of warning, but I always (ok, usually) carry a second one on bike. Power meter runs on a CR2450 battery, so not quite the ubiquitous 2032, but it also lasts a long time with fair warning. The shifters, honestly not sure what they use, but after 2000 miles and 18 months, their status lights are still green. What has been more of a problem is a few times my Garmin 1030 will end up not shutting down, then its dead when I go to ride.

Those shifter batteries are fantastic to last that long. Looking back, I think they've last that long on the gravel bike as well.
