    Why start the car when you have that car charger? You plug it to charge the battery..

    12V reading is not guarantee that the battery is good.. while it is holding 12V charge.. it should be able to at least maintain that with load

    Ah okay so no need to start the vehicle if reading is 12.5V because I dont use the vehicle. What will be my gauge if reading falls below 12V let say 11.9V then I have to start the vehicle so that it can be recharge?

    If your battery’s no load voltage drops below 12V, there might not be enough juice to start the engine. I guess 11.9V is just below 12V so the engine might be hard starting already.

    at 11.9, the battery can still possibly start the engine.. but by standards its already low thus needs charging.

    If within warranty period, just have it replaced.
