aaa.csv are databases of my AA and AAA batteries, respectively.
Each battery is labeled, and I track the date I purchased the battery, the
current capacity, the date on which the battery was last charged, and the date
on which the battery was last ran through the MH-C9000's refresh and analyze
(R/A) mode. Tracking this information in git allows me to build up a historical
record of an individual battery's performance.
The databases are tab-delimited CSV files. Fields are separated by multiple tabs so that the files are more pleasant to view in a text editor. If a graphical spreadsheet program is used, the program should be told to merge delimiters for viewing. The files can be also be simply viewed on the command-line.

Charge / Discharge Rates
Eneloop AA batteries have a listed capacity (C) of 2000 mAh. Eneloop AAA batteries have a listed capacity (C) of 800 mAh.
Maha / PowerEx recommends charging batteries at 0.5C and discharging at 0.25C. I've begun to charge AA batteries at 0.3C which seems to result in a higher capacity with no ill effects.
Charge: 600 mA Discharge: 500 mA
Charge: 400 mA Discharge: 200 mA
