What to do if your battery icon is missing?
If your battery icon is still missing after turning on the Power button in your Taskbar Settings, you should consider checking the Power settings with the troubleshooter. To do this, navigate to Windows Start Menu > PC settings > Update & Security > Troubleshoot. Scroll down and select the Power option. Click the Run the troubleshooter button.
How much energy is lost when charging a battery?
High current means more losses (it’s P~I 2 ). And if there are few losses this means there is a lower current. But then again this means that the charging process will lose less energy if the battery charged slower. And this means that charging a battery faster will create significantly more losses.
What causes a battery to go dead on an ECM?
Battery drain or dead battery A failed ECM power relay can also cause a battery drain or dead battery. If the relay shorts it can leave power on to the computer, even when the vehicle is turned off. This will place a parasitic drain on the battery, which will eventually cause it to go dead.
How is energy released from a battery when not in use?
Finally the chemical process releasing energy in the battery also occurs slowly when not in use and you loose energy over time with the battery just sitting. In effect there’s also a very high short circuit resistance. Every battery has an internal resistance. You can think of an actual battery as a perfect battery in series with a resistor.
What causes a car battery to lose power?
Opening a door or turning the ignition on with the main battery disconnected can cause the battery in the device to lose power as well. Door modules Loss of express-up feature due to loss of stored “pinch point” Engine control module (ECM, PCM, VCM) Loss of learned idle speed which can cause a stalling condition.

What causes a door module to lose power?
Most of these devices use a small battery to supply power. Opening a door or turning the ignition on with the main battery disconnected can cause the battery in the device to lose power as well. Door modules Loss of express-up feature due to loss of stored “pinch point”
What happens if you lose the ignition relay?
Otherwise, you will be forced to travel without your car. The ignition relay supplies power to essential engine parts like the fuel pump and the ignition coils. Without these components, your engine will die imminently, so you can probably guess what will happen if it can’t deliver power to them.
