batteries - Function to describe alkaline battery voltage under constant current / load - Electrical Engineering Stack Exchange
At what voltage depletion level do originally 1.5V alkaline batteries become pretty useless? Is it 1.2V, 1.25V or maybe 1.10V? In other words what would be your threshold for still holding on
