General comments

These measurements reveal very important information.  Two 5s packs were ordered in

Feb. 2008.  One was bad and was not replaced until Sept.  You can see the new

section in cells 1-5 and the old in cells 6-10.  The message is they degrade over

time even if they are not cycled.  I will confess to storing them charged but I

wouldn't bet that they'd be much better if I had stored them any differently.  If

all cells were in the 4 to 5 mOhm range I'd be very happy as this is a very light

weight pack at a very low price.  I will watch it and if I can get 100 cycles it is

a good value.
