Approximately how many volts from the battery do you need to be able to start the car.

Cold Mornings alot..
Warm Afternoons around 9Volts should do it.. But it is the Amperage of the start that counts

Yeah i just upgraded my stereo and now containes a distro block with a digital readout(volts). I had been playing around with the stereo yesterday and didnt start it. I tryed starting in this morning, the readout showed 11.9 volts and it wouldnt start.

if the battery volts drop under 9 volts while cranking the computer has not got enough power to run in most cars

so i presume you jumped it ? if not how did u start it

if your serious about your car stereo add a secondry dry cell battery that charges up like the normal one but will only output to your stereo, make sure the battery for the stereo is a drycell then u can fully enclose it and hide it behind a false wall or somethign.

the car was in the carport so i could jump start it. I pulled it out and charged it. i want to get a dry cell battery(optima or odyssey) but run it in the stock position. The only problem with that is the cost.
