IMIN:1 means, that it have reached last stage of charging/charging is practically finished (current accepted by battery is less than 100 mA, might be as well device power usage). VDQ:1 means "valid discharge quality", i.e. since last full charge (even if it just ended), discharge wasn't interrupted to the point of spoiling discharge measurement, so upon reaching edv1, new battery calibration data might get saved.

All those things are explained in calibration post, linked in my signature

As for 1500 mAh - depending on your usage pattern, relative capacity might be around 1500 mAh, but it is unlikely to seen for any variant of genuine Nokia's BL-5J. OTOH, for Scud's or Polarcells, relative capacity of 1700 mAh isn't anything surprising.
