Re: Solution for MB-D10 AA battery problem

I never checked the no-load voltage on my exhausted Ni-MH AA's, but based on my experience with the MAHA charger, I would say it's around 1.1 volts. The charger reports pushing 1900+ mAH back into exhausted cells, whose starting capacity (as measured by the charger) is 2100 mAH. I am using Sony Ni-MH batteries.

If there's just ONE bad cell in your sting of 8 cells, high internal resistance in that cell can cause the camera to shut down prematurely. Are you certain that all cells you use are "good"?

Also, I'm sure your aware that the camera draws a good chunk of current during capture operation, even more recharging the flash.  This draw will depress the cell voltage during use, and the voltage will recover to a higher voltage if allowed to rest.  I assume that camera measures voltage UNDER LOAD to report battery condition, as well as while "resting".
