Hacking battery management board to work without batteries?

I commend you on your efforts to extend your systems life for a life span longer than 10 years!

So far MacBook’s which are 15 years of age are still able to get batteries! So I’m sure you’ll still be able to get a fresh battery.

As far as hobbling the micro controller board to work without a battery I don’t know of anyone attempting that.

To be honest I don’t think that would be that good ;-{

One of the problems with laptops is trying to use them when tethered to a power brick or even external devices unless you have glued your self to a desk. As an example I’m sitting on my couch pecking away on my 2011 15” MacBook Pro watching the news and having my morning joe.

Running on AC without a battery would put your activity at risk as well as your systems drive as it would likely get corrupted.
