Most of Emergency lights in our houses fail to work at the right time. Because their Batteries have not exercise charge/discharge for long time, they are not able to take over or in luck cases, they start but end after a short time.
An idea came to my mind to make a SIMPLE timer circuit that will auto-exercise them by turning their power Off / On frequently.
The question is: What is the maximum time can I get of a timer ? even if it is not accurate. One week will be very nice. But is that possible ?
