Depends; if you consider "not having one" a battery "problem" then yes, your
928 has battery problems ;-)

9x7s have a battery that maintains memory for a limited time while the power
is out; they also depends on special firmware in HP-made HPIB and SCSI
drives to ensure data integrity during a power loss. Later 3000s discarded
both of those features, which is why HP started shipping UPSs as a system
component.

HP-provided UPSs talk to the systems to let them know when the lights are
about to go out (I think they simply cause a system abort of some kind to
terminate processing and disk I/O, but HP might have improved that aspect).
