Usually the batteries last about 3-5 years.  Certainly longer than 
two months.  But how old was the battery when you got it.  Since 
these batteries have a shelf life of 5-10 years they can have sat 
around for some time and still work, for a while.  Unplugging the 
power cord does increase the battery drain some, depending on model, 
I don't know specifics about the 7500.  The way to be sure is to 
measure the battery voltage.
