I don't remove it to charge it (or even disconnect it)! Should I?

In theory yes, but who does?

Modern cars don't like having the battery removed, they forget to
much.

If the battery has gone flat, especially if the starter motor has been
operated, the radio, clock etc will already have forgotten who they were,
what time it is etc.

Normally not when it just sags badly when trying to start the car.

With every car that I've had, if the battery won't power the starter (ie
even the courtesy light goes out when the starter is operated) the radio and
clock will reset.

I find that batteries will either give enough power to turn the engine over
or else will die totally under load, with no half-way house that causes a
gradual slowing of the starter over a few seconds. Usually there is no
warning. I get into the car and everything is normal, turn the key and all
the (interior) lights go out. I never start the car with the headlights or
heated rear window on, to give the battery every possible chance. Given that
my car is a diesel, which tend to need more power to overcome the higher
compression, I don't like to risk flattening the battery.
