The power manager needs the trickle current from the battery to function. So, no battery juice = no heartbeat.
Trickle current for the Power Manager on all PCI PowerMacs is supplied from a +5v/GND rail on the power supply (as is also the casein ATX PCs) so no PRAM battery is required to fire a 9500, or other PCI PowerMac. I've been there and done it.
