Generally speaking, anything below 12.6 volts (at normal temperatures) indicates either a bad battery or a very discharged battery. Anytime battery voltage goes below about 10 volts, the battery is damaged.

It's not only possible, but likely that your battery has already been damaged too much by all these discharges. It's also likely that your alternator is being stressed beyond what it was designed for by having to recharge the battery so much so often. That said, you really need to find and correct the parasitic drain issue before sacrificing another battery and alternator. I wonder what a dealer would charge to diagnose this problem?
