I need a circuit that will charge all of my 1.5 volt AA batteries but will not over charge the battery once it is fully charged.
I am wondering if a circuit board from a Yard Mushroom light will work to charge batteries? The solar cell is connected to the PC board and 2 wires go to the battery but I have no clue if this will stop charging once the battery is charged. If so I will need to build a 120 vac to 1.5 vdc power supply and remove the LED.
I have over charged and killed all my batteries again. I just bought new camera batteries a few months ago, good quality batteries from Wal Greens. I have my Wal Green battery charger on a 24 hour timer set to come on 1 hour every day. 1 hour is the shortest time I can set it for. I put batteries in the charger then do not remember to remove them until i need to use the batteries by then they are over charged.
I did an online search and found several circuit drawings but none of these show the voltage for the battery being charged. Ebay has pre built over charge circuit PCBs from china they are all designed for specific battery voltage and current.
I tried to charge my batteries in Mushroom lights but they all discharge after dark. LOL. Days are now short only 8 hours of daylight batteries never get fully charged.
