wall transformer output measurement

I have zilch experience in electronics but need to determine the voltage and current outputs of a plug-in wall transformer.

The unit will be used to charge a handle with 2 AA NIMH 1700 mah batteries.

Is there an easy way to connect between the transformer and the handle to graph the output (voltage and current) over a 12 hour time period?\

hi

are you actually going to use the plug-in wall transformer to charge 2 AA nicads or NiMH batteries? do you need the circuit design of this charger? if so what is the rated current output of your transformer, what is the voltage output (you will need at least 9v output and 750ma current output.

i have a designed circuit for that using the C/10 approach (slow charge) and it's also variable charging rate. ;) :D :lol:

The transformer output is: 12VDC 800 mA
Input: 120VAC 60Hz 16W

Yes I need to know the circuit design to know if there is any danger in using this type of transformer plugged in for long time periods etc.
