Most likely the 3.6v PRAM battery for Apple's at Radio Shack... about
Some macs namely Performas used a 4.5 V cube battery, but I believe the
7300 uses the standard 3.6V cylinder.
You will lose the PRAM contents... you're supposed to... disconnect
power. Pop out old battery... pop in new one.
Press CUDA button or logic board reset button exactly once. Wait 10
seconds... connect power and continue.
Reset your time and date.
