There's only 4 components to the charging circuit: the power adapter, the DC-in card, the battery, and the logic board. What you described could be a power adapter issue, a DC-in card (it's the card that has the female jack that the power adapter plugs into), a battery, or possibly even a logic board issue.
The only way to trouble shoot power issues is by elimination. Do you have another power adapter handy you could use? If you gently use a pen tip, does the female jack wiggle at all (bad DC-in card)? Is the system always plugged in (not good for battery life, as they need to be exercised periodically), if so, the battery count may be misleading. Is the battery several years old?
The female jack is solid. Yes, the Powerbook is plugged in 95% of the time, has been mostly that way since I bought it. But it does get shut down periodically and sits for two or three weeks before being plugged in again, which naturally discharges the battery. This is only the second battery I've had in this thing. It's from that Apple battery replacement program some years back, was it 2008?
Frankly, I'm amazed this Mac & battery has lasted as long as it has. My son, who is now 25, and I bought identical machines about a year apart (he bought his first). I think he's gone through three more Mac laptops since his Powerbook clamshell hinge broke down. I've always had desktop Macs as my main computer.

Given that a number of the batteries replaced as part of the program years ago didn't last more than a year, sounds like you got a good one. And since it's plugged in most of the time, my guess is it's time is due. When I replaced PowerBook batteries in our family machines, I went with OWC batteries, which worked well.
