Hello Arild and LF,

in the Apple Specs for the PB 160


there is no specific PRAM battery (like the 3.6 V Lithiums used in DT Macs
or the 4.5 V Raytheon "velcro style" Alkalines in Performas) mentioned at

So possibly all the PRAM data buffering is provided by the rechargable main
battery (any PowerBook specialists here?)

Newton and Mac greetings again,
