The scene: a vehicle sits idle (not driven at all) for up to two weeks.
When parked, there IS some IOD (Ignition Off Draw) that slowly drains the battery.
That IOD draw is not enough to drain the battery to where the car will not start.
However, IN the vehicle is also a cell phone that is used as an anti-theft device.
That's actually a fairly cool idea (me thinks), fully described at:
https://www.howardforums.com/showth...old-cell-phone-as-a-vehicle-GPS-tracker/page1
OK, it won't keep the car from being stolen, but it will Locate the stolen vehicle.
And a cell phone charger will drain the car battery if it is forever charging.
The problem: how to keep that cell phone charged, Without draining the car battery.
Is there a device that can be constantly hooked up to the 12VDC power,
and it can be set to Do Nothing (close to Zero power draw) for 22 hours of the day,
and for the other two hours daily it will allow power to go to the cell phone charger?
Hopefully, that will keep the cell phone alive without draining the battery too much.
Does it exist? Can it be easily built? Ideas?
Thanks, people.
