For optimal charge rates with the 9000, check out their faq:

With precharged Eneloops / Imedions or other LSD's, I only do one break-in cycle, and then just use them normally. Have some time on hand to perform the break-in, as the current in break-in mode is very low.
You can check the actual capacity of your existing cells by charging them up, and then measuring their capacity with a specific discharge rate of 0.2 * C and seeing what the display shows at the end of the discharge. If you do this on new cells, be sure to put them through a few complete charge/discharge cycles first - I just place them into service and know that after a few uses, they should be at the best of their capabilities.
Although mentioned in the faq, even though the display shows "Done" in the display, if you were to take them out of the charger at this point, they would be about 90-95 percent charged. For a true full charge, allow an additional 2 hours after "done" is displayed. During these two hours, a 100ma charge will be applied each hour (top off), and then it follows with the much lower 10ma trickle thereafter.
The very first voltage that gets displayed only once upon an initial charge, is the impedance check voltage. Some like to keep a record of this to track the health of the battery as it ages, beyond just measuring overall capacity.
As you can see, it is very easy to geek-out with the 9000.
