you have to get to the website thru google. clear browser cache. search "Silicon Chip Micromitter" in google, click on google's link. do not go the website directly. it's a bug.
the quick and dirty formula for constant current charging is:
(cell capacity mAH/constant current mA) * 1.4 = charging time H
so, for a 2500mAH cell, charged at 500mA:
(2500mAH/500mA) * 1.4 = 7 hours
during charging the cell remains cool to barely warm. when it is about to reach the end of...
