class=070420601-28022006> Yeah, I guess I forgot to point that
out. The time applies to a fully discharged pack (.9 ~ 1V per cell). At
C/10 it's pretty hard to hurt anything by "overcharging" i.e. charge a partially
discharged pack for 16 hours. At the higher rates it becomes a very real
possibility. Normally for "Fast" charging you'd use a good Peak detect charger:
0 delta V or negative delta V depending on the cell chemistry. For C/10
you can get away with a low cost constant current charger - but you do need to
shut it off! Ed also pointed out that new packs generally need a full 20 hours
on the charger at C/10. I would agree that this is a good thing to do, but
do remember to stop charging them at 20 hours. It's easy to forget. Better yet
use a timer, but if you go this route, make sure that the charger won't turn
into a "discharger" when the input power is removed.</SPAN></FONT></DIV>

<DIV><SPAN class=156521521-28022006><FONT color=#0000ff face=Arial size=2>You
are correct on the rate. The time is dependatn upon how much of the original
charge remains. A good charger will charge only as long as necessary to meet
its full chare specification (voltage,
etc.).</FONT></SPAN></DIV></BLOCKQUOTE></BODY></HTML>
