[A129 Pro Due] How long parking mode can last if set cut-off at 12v?

[Wilson]

My A129 Pro Duo (FW 2.4) connected rear cam and GPS module, powered by HK3 3-Wire ACC Hardwire Cable and record in low bitrate mode.

The battery voltage is around 12.5v just after switch off the engine, and set cut-off to 12v. The total recorded videos are only 3 hrs. That is normal or my car battery is nearly dead?

12.6 V and higher is a fully charged car battery at 100%
12.4 V is 75%
12.2 V is 50%
12.0 V is 25%
11.9 V is 15%
11.7 V is 0% - fully discharged battery

8 W are consumed by both car cameras = 666mA
3 hours = about 2A
I recommend charging the car battery .
Immediately after turning off the engine, the battery voltage should be greater than 12.7 V.
I usually have 13.2V - 13.8V, after 60 minutes I have 12.5 V - 12.7 V
Setting disconnect to 12 V - you will kill the car battery
I recommend setting 12.4V

the car draws up to 150mA after switching off
if other accessories are installed - alarm, car cameras - consumption is higher
if the car battery has a weaker capacity, the car battery may be discharged in 5-7 days

thanks your explanation

that means my battery is nearly dead and i should replace it?

charge the car battery first,
turn off the car camera at 12.4 V
check current consumption in A after switching off the vehicle
if the voltage still drops to 12V - buy a new car battery
