Only feasable time i could see that it could put a strain on any components is inital power up from 0V But they normally have a resistor for a longer Time Constant charge. Say Its a 1 Farad CAP with a 50 OHM resistor... T=50*1 Where Time=Resistance(Ohms) * Capacity (Farad)

Which would mean the capacitor would be 63% of supply voltage 8.72 volts for a 13.8 volt supply after 50 seconds.
