Question 1

What exactly does the conditioning mode do?  how does it compare to the refresh and analyze mode of the mh-c9000?

Accepted Answer

The Conditioning mode on the C980 is very similar to the Refresh and Analyze mode on the C9000, but with fixed settings.   The C980 will charge at 1000mA and discharge at 200mA where on the C9000, it is adjustable.

Question 2

What is the mah per aa and aaa battery that it charges at? Is it always 2000mah / amount of batteries?

Accepted Answer

There are 2 charge modes. Turbo Mode which charges each AA battery at 2 amp and AAA at 1 Amp. In regular mode it will charge AA at 1 Amp and AAA at 0.5 amp.

Question 3

Can you leave batteries on the charger after the charge is complete for extended times?

Accepted Answer

Powerex advises not to leave them in the charger. They do not say why. I don't think it makes any difference to the batteries. However, having a battery in a slot will keep the charger from going into standby/sleep mode, so the screen might remain lit. Doing that for a really really long time might eventually damage the LCD screen, perhaps. I don't think it's going to actually do any more charging, or damage anything electronically. But I'd heed their advice within reason. I can think of numerous other reasons to follow their advice and store the batteries when they are charged.

Question 4

Does this new model, with updated software, do a better job of refreshing older batteries than the older MH-C9000?

Accepted Answer

In theory, there should be little to no difference. In each case the battery is charged, then discharged to zero, then recharged as far as it will go. On the 9000 you can choose the charge/discharge rates. The 980 works at preset rates. Some people say slower charging results in a battery filled to a higher percentage of capacity, so I'd prefer to have that option. In any case the results should be similar. You'd have to measure voltage and mAh in both cases, but I would not expect huge differences. I also don't see why the device software should matter, as long as it is functioning correctly.
