After a few years of use, my battery pack finally died. The laptop doesn't even detect or try to charge the pack anymore.
So I replaced the cells in the pack for new ones, but that didn't make it to come to life again. I tested the pack's end terminals to see if there is voltage, but there is no voltage at all.
If I connect the pack into the laptop, it's not detected either.
The pack has what it seems to be a built-in charge indicator. When I press the button on the left, the first LED blinks for 3 seconds, that's all. 
I followed the intructions in here to try to revive the pack:
Connecting the voltmeter to the outer terminals, take a 100-Ohm resistor, tie one end to ground, and with the other end touch each terminal while observing the voltmeter
But had no success.
Is there something else I can do to bring the pack back to life?
Hardware details:
Laptop: HP Omnibook vt6200
Battery pack: 14.8V (8 x 18650 cells)
