Our trucks have been compared to rolling I-Pads. The truck is constantly talking to the mothership. I have a Walmart H-8 and I have a Noco genius 10 that if I am not going to use the truck for 5 days or more I will put the maintainer on and leave it. It’s not the fault of the battery and if you have a higher current draw, then that will drain your battery.
This is the longest it’s sat for since the new battery. I took it apart to build a harness for the paddle shifters (raptor wheel) and then my work week came so it just sat. I don’t like having to leave it plugged in but I guess with that many fancy features it’s going to be a requirement.
If you had a drain on the battery outside of the Ford planned drain, then you'll eventually get this. Turn off any drains other than the stock system. I went three weeks with the truck shutdown without problem on an H-7 NAPA Battery.
I can’t think of anything else that would be a drain. The dash camera is the only thing that takes power without ignition on.
Don't blame the battery if you have an additional drain on it. Find out the amperage of the dash camera. It might be trivial but might not.
Not blaming the battery. Just curious as to how fast this larger battery already got drained to a point of preservation. The dash camera SHOULD detect a low voltage and deactivate but I have no way of knowing if that actually works.
Detecting a low voltage is likely set down around 11 VDC. This will already be below your other alerts from the truck itself. Find out what its engine off current amperage is. That'll tell you whether its the problem. I installed a PWM LED backlight source. Its connected engine on or off. I've forgotten to turn it off a few times and it has not triggered any alerts after one or two days. So the drain makes a difference.
There’s 2 options. Under 11.6V and under 12.0V. I’ve just set it to 12 and turned off the parking mode. I’ll see if that helps.
Yes, give that a shot... 12 VDC is still kind of low for the truck systems but see how it works.
If you are using a maintainer, make sure you watch this video and wire it in correctly on the lead to the negative terminal vs. on the negative post. I typically drive my F150 - 3 days a week and my other vehicles 1 or 2 days a week. (depending on weather) No issues. I also have the Noco Battery conditioners plugged in.
No maintainer yet. My motorcraft battery that I replaced with this one wasn’t even this bad and it’s nearly 3 years old. I feel I got a bad battery and have zero confidence in this battery now.
