I can walk into Radio Parts and buy a little Arlec 6V/12V charger for $29.95, but I'm a bit stingy! Why spend that when I have a perfectly good 12V charger to which I can add some cheap resistors?

Hi Eric,
I'm glad you found another solution, but for anyone else reading this, please DO NOT USE RESITORS to drop the charging voltage. Modern battery chargers have electronics to do either a 3 or 4 stage charge, using different currents and voltages at each stage. Because the resistors do not act like a battery they will totally confuse the electronics and you may well damage the battery.
A 6 volt charger or a 12 volt charger with 2 x 6 volt batteries connected in series is the only safe solution.
Cheers,
Paul.
