    Today i have found my parasitic draw from my 0,7 car with new full loaded battery.

    It was a 2 Farrad cap from my stereo booster, thats sucked from my 40h batterie nearly 0,05 A.

    After remove its now 30mA rest. So 40Ah / 30mA ...one hour 30mA... 100hours 3A..

    So I believe its possible start my car after 300 hours..or ca 12 days..80% rest of load.


    says 30 days battery under 20Ah

    Don't forget the 5% self-discharge rate per month of a lead acid battery. :)
