Impossible to say without knowing the parasitic load on the battery during that week.
Getting a Lead acid battery from 80% charged to 100% charged takes about 3.5 hours on a healthy battery at higher absorption voltages, 14.4 to 14.8ish volts.
The more charged a battery is, the slower it charges.
I have an AGM battery which when absolutley stuffed full, accepts 0.0x amps at 14.7 volts. The X is because i have no ammeter which can read currents to this small level
If I start my vehicle with this 100% stuffed full battery, when the amps required to maintain 14.7v taper back to 0.0x amps, the battery can again be considered fully charged.
This takes about 45 seconds. This proves not that the battery recharges quickly, but that very little of the battery capacity is requred to start a modern fuel injected vehicle.
a 0.05 amp parasitic load is 1.2AH of capacity each day taken from the battery
A car battery is generally 65 to 85 AH capacity.
Voltage is electrical pressure, HIgher pressures cause more amps to flow, but a 80%+ charged battery can only be recharged so quickly, and this rate is pretty slow.
Best to always have a lead acid battery at full charge. Anything less is detremental to some degree.
