Recently installed a Blackvue 750 2Ch to replace my dead 650. Seems to be working great for the most part, but I did notice that it seemed to increase my phantom battery drain a couple of miles per day, but not sure as the weather is colder so hard to know where to attribute that loss.
However, this evening, I started the car and had the "12v battery needs replacement" warning. While it is entirely possible that it does need replacing, it seems a tad unlikely as it was just replaced about a year ago and my original lasted about 4 years.
I also know that the warning is triggered not by the 12v battery voltage, but by a measure of the amount of charge it is requiring from the traction battery. So if the new Blackvue is causing significant increased draw beyond what the car is programmed to expect it could trigger this.
Just looking to see if anyone else has experienced it. I'm out of warranty so the 12v replacement will be on my dime and if it isn't really necessary I sure don't want to do it...but then I have to figure out when I'll know if/when it really is needed.
Not using a Power Magic Pro, direct connection to continuous power. Am using Parking mode.
I have installed same camera on my previous Porsche Macan, which has only a 12v battery. It doesn’t drain it enough to cause problem, even parked for over 2 weeks
