A DIY Battery for the Macbook Pro

Yes, I am serious:
Backstory: Those batteries age, they can
swell. You don’t get them any more.
The battery compartment would be great
to house more harddisks (no problem to me use
the USB connections internally, i already use the
drive bay for s second harddisk) But a Macbook
needs the battery, not just for being mobile
but for keeping the settings or when the CPU
draws more power than normal.
So the idea is to put as smaller battery in,
thst just serves the mentioned tasks:
Supporting CPU, keeping settings. The Macbook
is used stationary at home anyway,
Has anyone had the same idea?
I notice as a multi threaeded wire goes to the
battery, the cells are controlled individually.
But no clue, whether battery management
is on the mainboard. Or if the batteries electronics
prevent a diy battery ad it would notbe recognised.
As a start, it is a 17‘ Macbook Pro, early 2011.
No further explanation of battery or power msnagement
in the service bulletin.
Best, Salar

Thanks, but I alteady replaced it.
This is not the aim.
The aim is to built in a smaller battery.
Advantages:
-The CPU still gets the extra power for intensive
tasks like rendering.
-Settings are not lost.

Without the battery, at least 2 HDs could
fit into the space. The Macbook, already
at 4 TB could be maxed to 8TB, without
carrying extra hardware, tapping USB internally.

But there is no info whether this
battery, developed in 2011
is completely passive, this
would make a swap / modification
probably easier.
But no idea how battery management
would deal with a much lesser capacity...

Of course I could probably run the 2011
Macbook without battery,
at least my 2009 model does...
