Charge controller ?

I don't guess I completely understand what my charge controller does and doesn't do so here is a question.

I have a PWM solar controller hooked up to 200 watts of solar and 2 group 24 battery's, controller is adjustable for shut off volts.Do I need to worry about changing the shut off volts while in storage or does the controller take care of the battery's and won't over charge them?

Say I have the controller set to shut off at 14.4 volts while I'm using it, should I change the shut off to 13.4 volts in storage?

Also where should I set the top end shut off, 14.4, 14.6 or ?

Thanks, Jim S.
