Of the eight (all are 2700 mAh Powerex NiMH 1.2 v nominal), the mean voltage was less than a half volt (0.45 VDC); the median and mode were each less than one tenth of a volt (0.06 VDC.)  The best of them was only 1.23 and 5 of them were at 0.06 VDC or a bit less.  So much for advertised shelf life.  Seems that the KX3 draws some trickle current even when turned off.
