If you believe this is the case for you, most vehicles have a way to turn off the proximity sensor in the owner’s manual. Reason 3: Other common culprits.
How to calculate the drain rate of a car battery?
The formula for these calculations was to take the parasitic draw in Amps and multiply it by 24 hours to get the amount of Amps per day being drawn. Then, we take the equivalent amp hours of a battery based in its RC or CCA rating (see my article link above) and divide it by (parasitic amps * 24 hours).
Why does my laptop battery keep draining after I shut it down?
Maybe you can try removing the battery after shut down and see if it still drains. An external chance might be that your battery has gone bad and is not able to withhold charge. But I’m discovering this problem just after I upgraded to Windows 10, nothing has happened like that before. Also, my laptop is pretty new, its only 8months old.

What does it mean when your battery drains overnight?
Why the Battery Drains Overnight A slow battery drain when everything is off is called a parasitic power loss. This happens when something – a glovebox light, an amplifier, any electrical component – is pulling power from the battery when it shouldn’t.
How long does it take for a car battery to drain?
A typical car battery will drain in 2-3 weeks and be unable to start your car due to the parasitic draw from the car’s electronics. With the negative terminal disconnected, a healthy car battery will self-discharge at 5% per month.
The formula for these calculations was to take the parasitic draw in Amps and multiply it by 24 hours to get the amount of Amps per day being drawn. Then, we take the equivalent amp hours of a battery based in its RC or CCA rating (see my article link above) and divide it by (parasitic amps * 24 hours).
How can I tell if my car battery is draining?
If after several minutes the amp meter is showing a high reading, then you can know for sure that it is time to start hunting down the component that is causing the parasitic draw. Common places you want to look at are the areas that we actually cannot see too great, such as the light in the glovebox or the light in the trunk.
