I am working on a prototype where I need to operate a very small DC motor at 1.5 volts. The motor pulls 0.15mA. I need the motor to run on rechargeable batteries (AA size) and optimze the circuit for maximum battery life.
1) What would be the best rechargeable battery for this purpose. I found a Li-Ion 3.7V 2600 mAh battery, but the voltage is to high.
2) For this type of application, is it best to run the batteries in parallel or series.
3) How do I regulate the voltage to exactly 1.5 volts.
4) It the motor is run constantly, what would be the maximum battery life?
I am really a novice at electronics (as you may be able to tell from the questions I am asking). Any help would be greatly appreciated.
Thanks
Craig
