It will start just fine. The fact that the wall outlet can deliver 667,000,000/330 = 2 million times more current than your auto parts shop battery is capable of is ...
Once the capacitor is charged in your circuit, no current will flow. If the capacitor is fully discharged, then the current at the start will be 100 V/8 Ω = 12.5 A, but since the power supply can only deliver 5 A you will only get 5 A during the charge phase. As the capacitor charges, the current flow will go to zero.

You need to know how much ampere your alternator is 50,60,80,120.. and read about how much power one turn off the engine can take in general,, calculate the drain of power and then the optimal recharge time based on the alternators power. You dont need to drive x miles to charge.
Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other. The car battery can move more charge than the motorcycle battery, although both are 12V batteries.
The end result is that you have to find the right battery combination of: Max. surge current or CCA; Total capacity, typically in Amp-hours; Size & weight; Cost; An 18 V lead …

$begingroup$ Using current and voltage introduces LOTS of uncertainties. Your calculations (and the ones in the answers which take your assumptions as correct) are WAY overestimated. You should take the starter motor power (usually 1-1,5 kW, that is still overestimated, if you consider the drop in battery voltage) and the time to start the car.
Removing the battery. Simply put the battery in a dry place between 40 and 60 degrees. Make sure the place is suitable, and even purchase a battery box if need be to ensure optimal storage conditions. This way, the battery will last from six weeks to six months, but it''s still a good idea to put it back at a three-month mark to recharge it.
Determine the battery capacity: Check your car battery''s specifications or refer to the owner''s manual to find the battery''s capacity, typically measured in ampere-hours (Ah). This value represents the amount of charge the battery can store.
The total charge a battery can supply is rated in mA⋅h, the product of the current (in mA) and the time (in h) that the battery can provide this current. A battery rated at 1000 mA⋅hr can supply a current of 1000 mA for 1.0 h, 500 mAcurrent for 2.0 h, and so on. A typical AA rechargeable battery has a voltage of 1.2 V and a rating of 1800 ...

A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
For front and rear drive units, it adds up to something like 1400A, as you would expect but presumably that exceeds the battery capability (with good reliability anyway). Also worth noting that those may well be PEAK current specs, not average current (the current to the motors is pulse width modulated in some fashion, I think).
The current depends on internal friction of bearings and brushes and wind/fan effects, as well as depending on the amount of work (wattage) the motor shaft is performing. …
How can i calculate the maximum current a battery can provide if the only information i have is: 7.2 V / 11.5 Wh / 1600 mAh. I know that if i can multiply C rate with Ah i can get maximum current of battery, however, most of the batteries lacks this information. Is there any other to calculate maximum output current of battery?
