That may be but some of this may be tied to the condition and usage of his packs.
I've seen the problem he is having with a couple of relatively new packs.
After a full charge/discharge/charge cycle, I could go back to the lower rate.
Even with NiMH's some manufacturers recommend a higher & longer initial "forming" charge.
That's kind of what I thought. I was intentionally setting the rate so that it would take 8-10 hours to charge, but maybe I need to look for 3-4 hours.
I was charging the 3400 cell at somewhere around 350ma, so it's probably just not enough to peak the cell. I'll try running it at something more like 850 next time and see if that works better.
Thanks.
