polarity of radio charging jack

[ozboater]

hey folks... still loving my sv despite the fact that i m on the stock POS radio system.... i figure i may as well build a decent stack of batteries before upgrading the radio... anyway, i m sick of going through expensive duracell batteries and i ve invested in some GP 2300 AA's for the radio... i was wondering if anyone knows the polarity of the small charging jack on the stock AM radio... it s a small circular jack with a centre pin ??? is it as simple as figuing the polarity of the jack and then rigging up a simple harness with a deans on the end ??? then i guess it d juct be charged on my MRC 977... i ve heard that very low amps is the key... can anyone explain the whole process to a stoked newb ??

cheers

Generaly the standard is the center conductor is positive and the outside conductor is negative. Just hook up a voltmeter and that will tell you which is which.

1C is always best.

IE:

If your cells are 1600 mah then charge at no more the 1.6 amps

or

If your cells ar 600 mah charge at no more then .6 amps
