help charging a life battery with a udc30

[MrWolf808]

can someone help me charging a new life battery on my udc 30, i can find the life setting on it anywhere, and when i plug it in the balance port it tells me the polarity is reversed, now i just bought the battery and i know i cant charge it on the lipo setting and i really dont want too blow up a 33 quid battery, please someone help me the charger is a little old now, and i have no idea where the other balance leads or the instructions are.

cheers guys
