 The battery in my 1400 is not being recognized, however, it is able to
 maintain PRAM settings. The battery tested at 10.8 volts, almost fully
 charged.

I thought my PB battery is 12 volts. If yours is 10.8 v. it's probably below
readable levels, and no where near fully charged. They're actually cells,
you know. I believe all NiCd cells are 1.2 v each. If they drop much below
1.1 v each, (that's where you would normally recharge them), or 11 v. for a
pack of ten (like the PB battery) it's in danger. Comes from a few years of
maintaining lots of battery packs for model aircraft.

Best regards,
Ken N.

The Apple service manual says a fully charged battery measures 11 volts.
