Hey All,

Quick question for you. I'm curious if I have one of those all too common but far too hard to troubleshoot mystery battery drains, so let me ask the folks here. For the second time in a row now, while my car sits in a dealer lot waiting for tranny parts, I got the notice that all connected features are shutting off to conserve battery. Both times it was right around the 2-2.5 weeks of inactivity mark.

Here's the thing, after the first time, the dealer couldn't get the vehicle to start or take a charge at all, so they said the battery was dead dead. Problem with that is the batter was less than a year old. Now granted, it wasn't a great battery so I said find and bought one of the OEM batteries for the heck of it, at $250 installed. Here we are, two months later, vehicle has sat untouched for just over 2 weeks, and I got the notice.

Does anyone here know if there is a standard time range of inactivity for where these disable connected features? or is it a tad smarter and the battery monitoring modules actually look at voltage, temperature, etc? And to be clear, the few power related aftermarket work I've done are the LED light bar in the grill, which using relays only operates if the vehicle is in accessory or RUN, and my aftermarket sub/amp, but I shutoff the breaker that powers that circuit sow it shouldn't be that either.

More hoping there is something like a default time frame of inactivity. I've had vehicles sit for 6+ months and start right up just fine, so the sensitivity of this system may be too much for me.

Pray it's not something like my mother in laws F150 that has had a mystery battery drain for 5 years, and can't go 2 weeks without use or battery is dead dead, no matter how brand new it is. I recently helped her trickle charge it, brand new battery after sitting for 3 weeks was down to 1.5V. She's had 3 dealers try to help her figure it out and so far no one has been able to figure it out.

I have no absolutes to add but I got the conserve battery message a couple of times myself. It seemed to me to be in the two week range of vehicle have no or little use. Now I put it on the trickle charger almost every week unless I'm putting some miles on it. FYI, I still have the original battery.

Nice, I'm technically on my fourth battery, but the 2nd and 3rd were the same Energizer brand from sams club. probably not worth trying to save money with that brand.
