The main question is "At what voltage does the PRAM start to die?" ----------Original-Post----------- I have a Beige G3 with dead PRAM battery. Can I wire in two 1.5v batteries in series to make 3V to keep the PRAM alive? The PRAM takes 3.6V, so would 3V be enough? What voltage does the PRAM start to die (reset)? ---------- Oh, I just discovered that 3 Ni-Mh batteries (1.2v each) makes exactly 3.6 volts. I'd prefer not to use rechargeable batteries though because they leak energy.
