I've been trying to move in to the more advanced levels of charging and caring for my NiMH AA cells. Recently I purchased a Maha 9000 and the BC9009.
I had 8 Tenergy AA's that I used in my son's RC controller so I pulled them out and did the break in on the Maha. They came off at a respectable 1900-2100 mah's for all 8. Since I purchased them sometime in 2009 and the rating was 2400 mah, I was pretty pleased with that.
Now after partially draining the batteries this weekend I popped them into the BC9009 and took the default 200ma charge rate and when they were done not a single cell showed more than 500 mah?
Wow I don't get it. Is the 200ma too low and the charging false quit before it was really complete? I thought that could only happen with too high of a charging current.
Any education would be appreciated.
Thanks
