>> AAA/AA NiMH Capacity CPF Member Tested - Please Participate - Now with Summary <<
Let's have one place to put all capacity test results for various AAA and AA cells. It will be interesting how different brands test vs. their rated capacity.
As you get new results, add them to the end of the thread.
Please use 0.2C discharge rate, after a 1-hour rest, post-charging. Also be sure to use a break-in regimen if the cells are new, or have been sitting idle for a while.
One report per cell please. Use the best value achieved.
SUMMARY AVERAGE of all posts:
(Updated 21 Jan 07 - Thru Post #66)
Green indicates a newer "Low Self Discharge" battery
Note that lower capacity standard-self-discharge cells are probably older cells, and may perform poorly due to their age.
