Do I have to disconnect the battery before spraying?

Essentially: yes.

If you have corrosion between the terminal and the ring, this spray is not going to emulsify corrosion down to a thin enough liquid to wash away. There'll still be corrosion in the contact area. You will very likely still need a terminal brush too. This thing's SDS(https://www.nkfr.org/wp-content/u...leaner.pdf) shows butane and propane. They are both propellants (so it gets out of the spray) but also in support for evaporation. No doubt it has water and propanol in it, so these gasses help dry these wetters but they require quite a bit of air exposure too. Keeping the ring on will risk leaving the contact surface slightly wet, just to get corroded again shortly.
