It would be interesting to see your NUT configuration.  If it would help you 
there is a shell script at http://rogerprice.org/NUT/nut-report which will 
prepare a configuration report.  (It removes passwords.)

Meanwhile, how old is your battery?  Very old batteries can produce exactly the 
effect you describe: crashing rapidly while still indicating high charge.
