A few things that people are forgetting.... I don't know about all cars, but I know my car 1989 Toyota Camry, does not like running without the alternator.

When the alternator is running the cars electrical system should be getting ~13.5-15v. With just a battery, the cars electrical system may only be getting 12-12.6v.

I know my headlights are dimmer, clock backlight is dimmer, sometimes acceleration feels strange some other glitches here and there, when voltage is lower.

Ideally, if you want to delete your alternator you should add a 7 cell lead acid battery (hard to come by). This would give you an extra 2v.
