PRAM stores things such as date and time, time zone, system volume settings
and some networking settings such as AppleTalk. None of these are critical
but they can be obnoxious if they get scrambled. Although OS X stores less in
PRAM than OS 9 did, it is still important, and there may be other settings
lost if your PRAM battery is low that you might not notice until later. The
1/2-AA style lithium battery that is used by most Power Macs is easy to find
from electronics stores and Amazon, and costs only a few dollars.
This is different from OpenFirmware NVRAM, which stores boot strings and
other startup information in non-volatile RAM which is not battery-backed and
is not affected by the PRAM battery.
