I've used laptops in the past, and they have usually re-charged within about 2 - 4 hours, during normal use. Re-charging overnight should have been ample time to fully re-charge.
Indicator-wise, on mine, there used to be a light that would blink to indicate that the battery was charging. It would change from orange, to green when the battery was full. The light was usually near the power indicator light. (I'm talking about on a Rock and previous to that, an Advent.)
Perhaps it would be worth speaking to CS where you purchased your battery - could be that it's faulty and not holding its charge (?)
