I know I read about something like this in this forum, but I can't seem to find it.
When my car had a security system installed, it came with a 12V 7.2Ah battery. It was hidden under an empty space inside the center console, right next to the gearshift. It is meant to provide back-up power to the security & vehicle anti-theft tracking system. It is isolated from the car's main battery.(i.e. only gets charged when the engine is on)
I was just thinking... these batteries are quite small and there is plenty of space behind the cigarette lighter socket to put another one it. I'll hardwire it to the wires powering the lighter socket, so it will get charged when the engine is on. Since my dash cam's USB adapter is plugged into this socket, it will get at least 12 to 24 hours
of power from the small battery. (no drain to the car's main battery, as the lighter socket gets no power when the engine is off) Edit: based on my dash cam's specs, my fuzzy math came up with 16.75 hours of running time, using this 12V 7.2Ah battery.
This way, the dash cam will essentially be recording on a 24-hour basis. Or is the a very bad idea?
I found out this exact same 12V 7.2Ah battery is also used by Verizon FiOS as back-power. Only $26 on Amazon.

picture below show the size of the battery... the yellow one that the woman is pushing into the Verizon FiOS device.
