It seems to me, there are 2 issues going on……
In the year & 3/4s I’ve my 2024 hybrid, I’ve had maybe 8-10 deep sleeps.
My issue is-
I can hook up a NOCO Genius 10 charger, let it fully charge,6-8 hours,
then, do a BMS/BCM reset, get proper indication of battery light,
lock the truck, double...
I have one which looks very similar. Works well, fairly water proof.
The only thing I did, added 6” metal strips/ double sided tape to reinforce the bed thin metal lip………Bill P
You should have checked voltage a 1/2 hour after opening… The 12.56v, was that at the charger hook up points, vehicle still asleep? 12.56v = around 92-93 % SOC.

FYI-
I have been monitoring 12 volt battery voltages over the past 36 days that vehicle has been driven.
On a day that the vehicle has been driven, I note the voltage before starting and then an hour after vehicle is turned off.
RESULTS: Avg. low voltage- 12.29v = 70% SOC; Avg. high- 12.51v =...
When vehicle is on, the DCDC converter will charge the 12v battery, providing voltage & amps determined by the PCM.
In accessory position, the same conditions happen, but don’t know for how long.
Vehicle off, battery voltage is shown, typically less than 13v, and there is an amp draw until...
Actually, the 12v battery runs all your electronic modules and systems only when the vehicle is off. Vehicle on, all 12v systems are powered by the DCDC system, which also is supposed to charge the 12v battery, of which it is doing a poor job…….Bill P
Hadn’t thought about that rather obvious cellular possibility! I’ll try just turning off the connectivity, and see if hourly voltage dip still happens……..Bill P
update 1/17-
Graphing before turning Connectivity off:
After turning off: still slight variation, but no constant 1 hr dips
So, this...
