At Radio Shack you can buy 3 AA cells for about fifty cents each and you can
get a battery holder for about a dollar and a half. Assemble this in a few
seconds and you have a 4.5v alkaline battery pack. Total cost is about 3
dollars. This will work with any standard AT class computer.

I have seen many 3.6 volt CMOS batteries replaced with a 6 volt battery
pack and with no problems being reported. I have never heard of any
problems resulting from using a 6 volt battery pack replacement for a 3.6
volt CMOS battery. If you want to take care to install a battery pack that
matches the existing 3.6 volt CMOS battery, then you can use a 3.6 volt
battery pack designed for a hand-held cell phone. This would be a very
safe choice for a battery replacement.

True! You all take great care now. When in doubt, check it out.
