Hello-
Thanks for taking the time to read my question. I have a few questions I need answering regarding a project I am working on.
First some background information about my project:
-It is powered by a rechargeable 9V 600mAH battery
-The components I have within my circuit are; two vibrating motors, a voltage regulator using two resistors (10K and 1K resistors), a Bluetooth HC-05, an Arduino Uno board, and a H-bridge (L293D)
-the load of the current is 304.1mA
QUESTION 1: Is the correct formula for battery life [mAH of battery/load of current in mA]?
Using this formula my battery life would be around 2 hours. Am I correct with my calculation?
QUESTION 2: Does voltage of the battery influence the life of the battery? Or is it solely dependent on the battery capacity and load of the current?
QUESTION 3: What are the best ways to prolong the battery life? I need my battery to last at least 2-3 days if possible before needing a recharge. Is it possible somehow to put the circuit in sleep mode when not in use?
Thank you for answering and let me know if any part of my post confused you I tried to explain the best I can.
