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 …

power
By this, the nominal power P = U I of the starter corresponds to a current I that is higher than what you compute with U = 12V (e.g., if the voltage is drained down to 6V, the current is twice as high to have the same power). Also, note that the power corresponding to the loss of voltage and the same current produce heat in the battery...

19.2: Electric Current
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.
What you need to know about battery charge current
