I have 7 ultra-bright chasers always running. I change the 2 AA alkaline cells in the red and orange ones and the 4 AA alkaline cells in the blue and bright green ones when they get dim.
Recently my blue and bright green chasers slowed down. I thought maybe because they are at the window where it is cold and maybe they are affected by the low temperature.
So I moved them to where it is warm but they are still chasing very slowly. The PWM brightness control was always bright and would not dim the LEDs anymore.
Today I measured the battery and each AA alkaline cell is only 0.66V!
The LEDs are still pretty bright.
I think the old battery cells have been running the chasers for 6 months or more. I changed them and the PWM brightness controls work perfectly and I nearly burned my eyes out.![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
