    As long as your car starts first time, and is charging properly, no reason why any old battery shouldn't do it.
    You also got to remember that a smaller capacity battery will charge more quickly, so will be at top more often.

  3. Within certain parameters yes.

    How much power do glow plugs take, before the starter even asks for any power, then the ignition and controls power etc

    Yes really.

    It was an 063 model, my van should/does now have an 019 model.

    Talking of volts ever tested the volts on a battery when cracking an engine over, some time can drop as low as 8 volts but will still start.
     

  5. Thats when the amps become important.

    Starter motor draw is the figure to watch and compare at the same time as the volts falling

    That depends on the ambient temperature, if cold glow plus warm longer drawing more power, in the summer don't even come on.

    Back to amps again, which is what the OPs battery hasn't got. ;)
     

  8. Tested how, as i asked before.

    No tester i know of, other than big bench equipment, that can test that figure, and believe it or not that test will take around 4_6 hours . Yes
     

  9. They can come on in summer, and sone stay on with engine running up to certain temps

    Nah. ya put a load over it, test for drop, mark a figure, see if it recovers with load off. Test again.

    Mr. HandyAndy - Really
     

  11. That isnt an ah test.

    Its a valid way of testing a charged battery though

    Well if you lose 5amps in a minute, you can soon work out the strength and time left.

    A simple test for the charging system is a volt meter on the battery when engine running, should be a minimum 13.5 volts but no more than 15 volts.

    But at the end of the day my money is on the battery being dead.
     
  14. And you get this amp figure to begin with and compare, how exactly ?
     

  15. Very few cars will tolerate 15v, max is normally 14.5/6.

    My money is on the charge system, likely to be alternator.

    But it could be the battery, just needs a proper charge and test

    You measure the amps at startup, and at end.

    Regulator sorts that out.

  19. Unless it fails and allows overcharging.

    Result a dead battery, but actually a charge system fault
