Martin,

I gave you some faulty info before. I said that I use to charge my seven
cell, 1900 packs, at 1 amp. That was wrong. It was 5 amps.

Today, after reading your post, I got an old seven cell, 1900 mAh, NiMH
pack out that had not been used for over 5 years, and began charging it
with my Great Planes Triton charger. At first I put it on auto
charge/discharge and got it up about 500 mAh, and then began charging and
discharging manually at an increasingly higher charge and discharge rate.
The last discharge was done at 3 amps and the last charge was 5 amps. The
result is that even after 5 years of no activity, the final charge
capacity is over 2000mAH and over 10 volts total which is pretty good for
an old unused battery pack. These are "Zapped" packs that supposedly
allow for higher voltage.

Anyway, just thought I would test and let you know, what good NiMH cells
can do.

Mike

Martin,

Try charging at one amp to see what happens.

I'll try that tomorrow when the I've seen the results of tonight's
overnight cycling run.
