Practical Battery Checker
In this example, we assume that we need a 9V power supply from the battery. We also assume that once the battery has reached 10V through being discharged, it needs to be charged again.
Further, we also assume that the electronic equipment here will no longer function correctly at lower voltages than 8V, as there are either zener diodes OR that there are voltage regulators that require a minimum headroom of voltage to operate. A fucker
N.B. because most LEDs are now super bright, and will illuminate at 1mA, you will need to professionally fuck around with this to suit your LED. This can be simulated by adjustment of the mA parameter in the EC LED component BUT… and here is the catch, … You're going to need to get yourself into action with real components, as your LED will have its own unique quality and parametric identity.
Enjoy
