Default Battery charger By MacGyver!?!?!?

Hello again everyone!
I have got 2 cheap batteries from H&K today. I have measured voltage it registered 3.8V. That is good. Label says 1700mA so 200Ma less than Leica original one.

Anyway I have read this forum previously, and I have found A genius Dr. MrakNorton`s modified battery charger. From His picture I figured out only 3 contacts from battery charger. and Which is negative or positive.

I found this Pentax charger on my desk and spec. is similar to leica original. 4.2V output 660 mA. I know leica one`s output is 3.7 V exact according to label. But close enough.

I have connected some wires and metal pieces at end of each wires. ANd connected end to Pentax battery charger(didn`t solder them because I still need this charger).
I have connected battery and Red lamp came on(means it is charging-green lamp at full charge). I have placed whole CIRCUIT in a controlled environment(Postal Box!).

I am waiting now to see if lamp will turn to Green.

I am not expert of electronics. I only know positive and negative. But I do`nt see why this doesn`t work.

I will let you know. Or Expert Advice please!
