completely cutting of power reduces iMac lithium battery life?

I have been told that completely cutting off the power (via a mechanical
switch) to an iMac G5 during non-usage times could reduce the liftime of
the build-in lithium battery. Is that true? Can I find a statement from
Apple on that issue or any advice pro or against completely cutting off
power?

As I understand it, with the computer shut down but still connected to
a live power source you have a trickle of energy going in to maintain
the PRAM settings. When you kill that power source, the PRAM battery
kicks in to maintain the settings. The longer it shut down, the more
the battery drains, and it not a rechargeable battery, so yes, youl
reduce the life of the battery. Have a friend who routinely shut off
her power strip after shutting off her iMac. Battery died in about 18
months. She doesn do it any more.

You don't need a statement from Apple to understand that.
It's not exactly rocket science.

I'll "me-too" that. My mother used to run through a battery every year
until I convinced her she didn't have to switch off the power strip. And
they were $15 batteries for her model.
