If the coil is open circuit or has a shorted turn - no noise, replace relay.
If the internal relay contacts are burnt and dirty from arcing there'll be a single click and no other noise - so clean contacts.
If the contacts have welded themselves together - starter will continue to whirr with ignition switched off - replace relay.
If the battery cannot provide enough current without dropping volts enough for the relay to drop out (rinse, repeat, 'rapid clicking' or 'buzz') then either shorted cells (most likely) or a narrow value window of internal high resistance. In the latter case it's probable that a battery terminal will get hot. Replace battery.
