Measuring voltage without load is meaningless, you need to apply a
resistor to the battery. However, most of the times I'm working on an
opened PC, I preventively replace the battery. Why not replacing a
battery that is still good, when you anyway do something on the PC,
instead of waiting until it fails in the most unpleasant moment?
Sustainability and environmentalism might be reasons, but regarding the
CMOS battery and the issues it could cause, those reasons aren't good
enough for me. What looks like a broken mobo, power supply, hard
disc, often is just a weak battery.
