What? Most laptops on the market today have removable batteries, to the point where you can buy spare battery packs for them for long trips. Same with a lot of smartphones.
Unless of course you mean Apple products.
There are few consumer laptops with removable (pops right out) batteries these days. I haven't seen one since the early 00s.
At best there are still those which are user-serviceable (requires a screwdriver and some finesse at the least). And Apple products where you cannot do even that.
Some business models still have the external removable battery, but have lower specs and higher price than consumer counterparts.
Almost no modern smartphones have removable batteries. It's rare enough that the LG G5 tried to make it a selling point a few years ago.
* Nexus 4
* Nexus 5
* Nexus 6P
* Samsung Galaxy S7
* Samsung Galaxy S9
The only recent phones I was aware of with removable batteries were the LG G*, but I don't think the latest model of those has a removable battery anymore either.
Even though swappable batteries do continue on the low-end, I think maybe [in the US] only Motorola actually makes spare batteries available for consumers to purchase, even for devices that don't have readily swappable batteries. I think this year Motorola will ditch swappable batteries, pretty sure, but will supposedly continue to make spares available for select models via Ifixit.
