Another suggestion about your short trips: Are you using your daytime running/head lights? I turned mine off on my 98 V70t5. Two 11 mile trips everyday may not be enough to keep the battery fully charged - and not to mention that your engine is probably not getting up to temperature for a long enough period to drive off water vapor, but that's another issue.

Did you measure the charging voltage? A Pb acid battery has a nominal 2.2 volts per cell or 13.2 volts total for a "12 volt" battery. Your charging voltage should obviously be more than 13.2v. More than 15 volts might be way too much. I'm gonna go measure my 98 v70T5 "standby current" right now...
