I have one of the early Macbooks with a non-user replaceable battery, and I'm using it today, 6 years after I bought it, and the battery is still fine. Sure, the capacity is a bit lower (maybe 50%), or I could get it replaced for around 150€.
Apple introduced non user replaceable batteries because it made sense: capacity and longevity was at a point where the average customer never replaced their battery.
