iBook BATTERY slowly dying?? "No, dead!"

I have a Dual USB 500MHz iBook. I've noticed that over the last 6 months or so the battery time has been slowly draining away....
Could the battery be dead? Or could it be the iBook itself?
iBook battery? YES
iBook itself? NO, not likely.
When my 700 started acting up, I took it to Apple authorized dealer, purchased new battery, popped it in, problem solved... well, almost.
A few days later, I couldn't start my iBook with the new battery! No matter what I did, it seemed DEAD!!! Not even with the charger plugged in. D E A D ! I feared it was the iBook.
Took new battery OUT, put it back IN - still did not work
Put OLD battery IN - worked fine.

Restart with OLD battery, still OK.
Replaced OLD battery with NEW battery - everything has worked great, which has continued for last half year, quirk has never repeated itself. Go figure?
CAVEAT: Moral of story, do NOT throw the old battery out right away; you may need it. Luckily, I had saved it for a "backup" battery.
Mark on it with a marker -
date you replaced it, and
status "Bad" or "dead" so you or someone else does not mistaken it for an extra good battery, then put "old" battery in the box the new one came in, place it on a shelf somewhere and
keep it for about a year as a BACKUP battery, then toss it out (recycle?).
If you are wishing the old battery in your iBook would suddenly stop acting "old", and
regenerate itself becoming "new" again, let's be real and get a life! A battery is non-organic, dude.
Stop kidding yourself about the need to spend $129 USD for a replacement, and move on with your life and that of your iBook.
(How do I know about this "battery denial" problem? Because, like a dummy, that's what I did to myself for about a week; I couldn't accept that my poor iBook's battery was dying! Yes, I was suffering from "battery death denial", but was this over feelings of attachment to an old battery? No, reluctance to fork over the cost of a new one! Fear of paying.)
Replace its battery and
get on with your life, and the iBook's rejuvinated life.
If not, you will not only end up with a very dead iBook, buy you could develop what is known as PTSD-OBD, or Post Traumatic Stress Disorder - Over Battery Death. This emotional condition though psychologically painful is rarely fatal for you, only the battery.
AFTER THOUGHT: Because of what you describe, and what I experienced while trying to use the charger to operate the iBook, but with a dead or dying battery we were hampered or prevented from doing so, I wonder if the battery module has a control "chip" or something in it which "thinks", or if the iBook's own battery control was just acting sympathetically to the battery's death. Ah, what geeks do ponder.
