thinkpads have this. I use "the tumor" (a 9-cell battery) and it's amazing. Also, you can hibernate the computer, remove the tumor, and replace it with another tumor (or the 6-cell battery), and restart- no reboot required to switch batteries.

Not only the tumor (which also made a decent carrying handle), but also the dream bottom plate battery OP is describing: https://www.amazon.com/Thinkpad-Battery-19-Cell-Slice/dp/B00...

Some models also have internal batteries, which allows one to switch the external battery without even hibernating.

Hot swapping batteries is so amazing. I use my small one when i keep it plugged in and change to the big one when i take it out. Never have to restart my laptop just because of that.

Even HP Pavilions (used to) have the option, flat or raised based on cell count

OK, I'll have to guess this is an older model TP?

No. Latest T and X series from Lenovo have them, probably other lines as well.
