Test the battery with a load tester.  Sounds like the battery has a bad
cell.  The place that sold him the battery should have a tester, or it's
a good excuse to buy one (the wire resistance type is only around $50 for
a good one).  Having a tester is nice because it can either finger or
eliminate the battery when there's a problem, and you can identify
problematic batteries before they leave you stranded on the coldest night
of the year in the middle of nowhere...
