However, I saw some videos and people usually do connect batteries directly with capacitors. Also, the current that flows from the battery to the capacitor is somehow of low magnitude, since it takes some considerable time to make the capacitor have the same voltage as the battery. I would like to know why this happens, thanks.
To install a capacitor, start by disconnecting your car’s battery ground terminal so that you can work safely. Next, mount the capacitor somewhere close to the element that needs more power, such as the headlights or stereo system.
Once the capacitor is mounted, connect its positive terminal to the positive terminal of the battery using an 8-gauge wire. Then, connect the negative terminals and reconnect your battery's ground terminal to restore power to the entire system. For tips on how to charge a capacitor, read on!
It is fine to connect them when the output voltage of the supply and the voltage across the capacitor are close to each other. If they are not close to each other, you may get a spark at the moment you connect them. The spark can suprise you with the amount of energy it delivers.
In my understanding, theoretically, when an uncharged capacitor is connected directly to a battery of, let's say, 9 volts, instantly the capacitor will be charged and its voltage will also become 9V. This will happen because there is no resistance between the capacitor and the battery, so the variation of current by time will be infinite.
The capacitor charging circuit is simple: a series resistor R1 to limit charge current through D1 into the capacitor bank C2. If the power-up events are rare, the energy loss on R1 is not substantial and doesn't have undue impact on the energy efficiency of the device.

By connecting the capacitors directly across the battery, the voltage of the capacitors is constrained by the battery; since the capacitor voltage cannot vary* no energy* can be extracted from or returned to the capacitors.
