Ok, so after some traveling I came back to work on my 9114 with all the tips I got. The new battery arrived and full hope I went into swapping the old battery out for the new.
And, as many here have said alreday, it really indeed was very simple.
Checking all contacts, I closed the battery up, plugged it into my 9114a, plugged in the power and turned the 9114 on.
Hurra!!! it worked, the two leds were on, we heard some moving off the head and after a few seconds the 'fault' LED went off. All seemed great.
However about a minute or so later, all lights went off. and no amount of trying from my side was able to make the 9114 turn on again.
So I opened up the battery and started checking some contacts. And somehow there was no current going to the plug into the 9114! I checked the battery - 6.5V, the current went to the PCB but did not come out the other end. I was stymed!
I though, okay, maybe the charger burned it - it had 12v coming out of it and maybe that was too much (though the label on the battery department said 20V max. the charger I used, by the way, was a standard HP charger, I believe 82059b)
As I have a second battery pack, I did the same thing again. Swap out the old battery. Check the contacts. Close the battery, plug it in, turn on the 9114. Hurra! both LED on, the 'fault' one went out after a few seconds. And a minute or so later, the thing turned off again. And when I again checked the output of the battery-pack, there was no current coming out of it!
I'm quite flabbergasted how turning on the 9114 could burn out some part of the PCB in the battery!
Anyway, are there any good ideas out there on what to try next? I will let the charger be plugged into the battery over night to see if that does anything (i do not know if the battery was full or not when I got it, however it continued to show a very steady 6.5V when tested directly. )
