Re: [tech4all] Jump start problem ...

1) Define "frequently".  If this occurs after "over night" or  after "parked at the airport for a week" it could be different.  2) test the alternator for sufficient charging current  3) check the alternator belt to insure proper tension.  Insufficient tension will cause a drop in charging current  4) check the vehicle for a heavy drain while parked.  Use a  current flow meter to see how much the car is drawing while  "off".  You could have a small short in a wire somewhere, or  something like the radio is staying powered up.  5) check the age of the battery.  If it is a liquid cell, it might  be possible to refresh the acid, or have a shop "boil the plates" (a  very old technique).    Voltage adds in series; current adds in parallel... so..    As for "D" cells or "C" cells... 8 in series makes 12 V.. No  problem.  But, if these are 1AH, then to make the equivalent of a  car battery - which could easily be hundreds
 of  AH.. you would  need hundreds of "sets" of 8 batteries in parallel... I'm thinking that  would be a LOT more expensive than a new car battery.    If the car is fine once started, and runs/stops/starts reliably during  the day... then you can pick up a "spare" battery or one of the "jump  start" batteries to keep in the trunk.  You can also get an  automatic battery cut-off switch (check an RV dealer) that will  basically disconnect the battery when it drains to a certain  point.  You have to "hit the switch" and start the car to re-set  it.  that way, whatever is draining it can't drain it past the  point where it has enough power for a start.    Then again, it could just be that the battery is going bad.    Good luck!  Prabirkumar Saha <[EMAIL PROTECTED]> wrote:                                I have a car related question. I  frequently face the "dead battery" problem while starting the car.  Repeatedly, I have to call up a friend to request for a jump start. Is it  possible to have a easy solution? If I
 keep few 1.5 V batteries in series to  make a full 12V, will it be useful? I know the amperage  is a problem. How to solve it?
