He said 'shifter battery' which is the coin cell in the shifter button. That is the battery that should last '2 years'... but when it dies, then you are DOA on that ride. - Update to this note: you can shift the derailleur and actuate the dropper without the remote. There is a button on each that allows you to actuate them locally. So you if your shifter/trigger dies, you can put your seat and/or gear in a spot that works and get home relatively comfortably.
I treat my shifter batteries like other preventative maintenance - check it once a year, replace if it's getting low. But if you just ride and put away, you can have an annoying failure for sure!
