2018 battery, surprisingly doing well

[D.J.]

I recently went on vacation for nearly a month ...

Left Jan 5th, and Jan 30th is my first day back at my car...

I have a BM6 logging battery voltage measurements every 2 minutes....
Voltage can be seen fluctuating with extremely cold temperatures we had.



Jan 22 was -16°C measured at the battery.

And to my very pleasant surprise, she fired up with relative ease today, after 25 days of being parked. Cranking voltage only dipped to 9.01v

I honestly was prepared and expecting to come home to a dead battery.



I even recorded this video (for the sound), expecting the battery to be not powerful enough to start the car.

This was a very long post to simply say, my car started today, and I consider myself lucky. My original battery is 7 years old now, and I do nothing special to maintain it, other than disable ISG automatically every drive cycle

I make sure to click every @D.J. Toro video purely for the soundtrack.

On a more serious note, I'm conflicted between being pleased by how quickly/easily your 6 year old battery cranks over after a month in arctic conditions, and the fact that 12.0 volts is half empty.

As I've mentioned in other threads, my 2022 has never sounded slow/weak to crank, even after sitting, but decides to hang out at ~12.3 volts (~70% charge), low enough that Coasting won't activate. I'm 90% sure it's by design, but it seems odd to let it negate a feature, and I'd like to know whether it's to prolong battery life, or just eek out slightly better mileage.

This one was entirely unplanned...
My wireless android auto connected and was playing quicker than expected.

one of the benefits of a trunk mounted battery is they are not exposed to the high temps in the engine compartment, and thus last much longer. Aside from limiting our spare tire size, the Stinger has an optimal battery location for weight distribution as well.

Wish I would have seen that BM6 device earlier, may pick one of those up soon. Unfortunately mine started dying over the past few months, and then 2 weeks ago, I had to get my wife to bring her car to my location for a jump to get it back up and going. I was no longer allowed back into my house unless it was replaced, hehe. I think between the GT2's extra bells n whistles, proximity door unlocks, and led grill lights I left on too often drained it too much.

my batteries will typically last 7+ years. i'll throw them on the trickle charger every month or two to get a full charge.

with the Stinger, i disabled ISG pretty much immediately when i got the car (1k resistor mod).

I went on another vacation! This time 39 days between starts of my 2018 Stinger.. (May 26 - July 4)

This OEM battery is a beast.




I half expected it not to start..
I thought surely, after sitting for 39 days, this would be the end of it.

Battery voltage was 12.1 before turning the ignition on.
