voltage
$begingroup$ The charge voltage depends on the battery chemistry. Some lithium ion batteries are charged to 4.2v, some to 3.6v, etc. And the battery voltage will vary with the current charge state - less charge means less cell voltage, but the relationship is not linear (quick drop from completely full, flatter plateau for a while, quick drop again when getting low).

The charging process reduces the current as the battery reaches its full capacity to prevent overcharging. For instance, a lithium-ion battery may charge at a constant current of 1C until it comes to around 70% capacity, after which the charger switches to a regular voltage mode, tapering the current down until the charge is complete.
The charge and discharge of a capacitor
(Figure 4). As charge flows from one plate to the other through the resistor the charge is neutralised and so the current falls and the rate of decrease of potential difference also falls. Eventually the charge on the plates is zero and the current and potential difference are also zero - the capacitor is fully discharged.

circuit analysis
Look at Figure 2. At the instant the switch is closed there is 9 V on the battery and 0 V on C1. That means that there is 9 V across R1 and R2 so current will flow. This is basic Ohm''s Law $ V = IR $. Current is the rate of charge flow. If there is current then there is a movement of charge from the battery to the capacitor.
