update: i connected charger to a 12 volt car lead acid battery which has 9.83 volts left in it.
when connected it is now a descent 12.85 volts reading whilst under charge.
the run battery is an identical type of battery with 11.95 volts.
these were both replaced from my cars a good 12 months ago.
i know if i put the 9.83 volts battery to my regular transformer battery charger i can only get it to about 11.5 volts fully charged, so this will be a real good test for the new charger.
when its finished i will swap the batteries around.and charge the run battery. i also measured the run bats 11.95 volts so i can see how much gets sucked from it, if any.
it too will only ever charge to 11.5 volts when charged the old way.
my next project will prob be a bedini motor?
i would like to tell all that this new hobby of mine is probably the best ,most interesting thing i have done in many many years.
i am learning more than i thought possible and i am very eager to experiment with all these new toys.
now that i am getting the basic concept of this stuff i have a lot of ideas of my own that i cant wait to try out and experiment with.
there are just not enough hours in the day for me now he he he.
