You can get replacement (better!) batteries for almost any handheld gaming console that have been around for that length of time — I’m pretty sure with the volume of electronic groupsets being sold the same will ring true for di2 and axs.
Also, mechanical groupsets have plenty of waste in them. Yearly to biyearly cable and housing replacements add up for shifters. Probably less overall impact than lithium batteries but not nothing. So many things in our lives run on electronic motors, I dont get why cyclists fetishize cables and act like electronic groups are some high tech gizmo. The only negative is the cost, they shift so much nicer and require almost no adjustment.
