Without more diagnostic info, can't be too sure.  Rapid death of a
battery can be due to a bad voltage reg.  Maintenance free batts can
still dry out if overcharged.  Under charging can occur if alternator
diodes fail.  Check charging volts, try to get some water into the batt
and check specific grav, verify alternator output current, verify good
cable connections everywhere.
