Thanks for the excellent review. I recall attempting to read it when I was considering the MH-C9000, but most of it was "over my head".
Now that I have had the charger for a month or so, I wonder if my model is newer than the one you reviewed. Perhaps it has newer firmware? I didn't observe if anyone else during this thread reported this. If so, my apologies.
[EDIT] Wrong.
The reason I mention this is that the default for CHARGE is now 500 rather than 1000.
[EDIT]: Wrong. My error. I had been using the C9000 to pre-discharge prior to BREAK-IN, related to another OP. I got the default DISCHARGE rate (500 ma) and default CHARGE rate (1000 mA0 mixed up.
I am a CPF newbie, so perhaps the default is different for different batteries. That doesn't seem to be the case, because with every AA and every AAA I've put in the MH-C9000, it has wanted to use a default CHARGE of 500.
I don't know if other things have changed. Maha may have some kind of "change log". I wonder if there is a way to "flash" the firmware, like you can with many devices. That seems unlikely, as there isn't any provision for USB or flash card.
The MH-C9000 is part way thru a BREAK-IN, so I can't check the firmware version until later. Do you recall the firmware in your test device? Or is it in the review and I didn't notice it? Is the firmware version something that shows up when it powers up?
