Genuine Apple batteries are miles better than any of the secondhand ones I've replaced them with (even the iFixit batteries).

Very exited to get my hands on the OEM replacements and extend my laptop's life another 3-5 years

They are offering this only for this year's Iphones and at some point this year's Macs. It doesn't seem like you can get a battery for 3-5 year laptops nor that you'd be still be able to get a battery for this year's laptop 3-5 years from now.

That probably remains to be seen. I imagine batteries are one of the most desired parts that they're going to make available, and assuming that they put a healthy Apple-sized margin on the prices, why stop selling them after a new product comes out?

It's possible but the reasons not to would be because the margins on a whole new device are larger and because carrying and producing old parts has costs.

Don't they still offer battery replacement services for those devices? If so they're already bearing the cost of producing/carrying these old parts. In fact, they could potentially make more profit selling these parts by themselves to end-users considering how much demand there is for things like batteries.

This. Despite all the talk the “oem” stuff on eBay is crap. You really understand why apple does the warnings on battery - is careful on repairs

I installed two iFixit MPB 2015 batteries, the second one as a free warranty replacement. Both degraded incredibly fast.

I just received mine for the MPB 2015 this week, original battery (which I doubt was genuine) is bloated, but still held up in terms of capacity to originals according to coconutBattery[0]. Will monitor the iFixit one closely as well. But I still trust them better than random China or local seller.

The degradation is the real problem. They hold up for the first tens of charges but quickly lose 20-50% of capacity. It might have to do with the lack of OEM charging circuitry on the replacements, or perhaps just shoddy quality

Would capping the max charge at 80% make any difference for this? Apple seems to do it with their latest phones and laptops. I don't plan on using the laptop on battery for long times. So my main concern is just keeping it at a 2-3 hour capacity for the upcoming years (mostly plugged in) and not having it bloat up like the previous one, making the laptop a fire hazard.

Correlates with my experience of late 2013 MBP batteries (it might be the same model actually). My original Apple battery lasted until 2019. Both of the iFixit replacements have lasted a year until not holding original charge, and just last night I noticed a cell starting to swell.

I doubt I'll ever find factory original cells again for the 2013 but if Apple sells them I'd consider buying a MBP again.
