:ö: The li phone charger you found would do, if you will try and test the output with your voltmeter, sometimes the output is a bit higher than what is written on the label, which is normal, because for you to charge a battery, you'll be needing a voltage higher than the voltage of the battery you are charging, but i'm quite skeptic with the 1.1Amp output...this will full charge your battery rapidly which may damage your cells, more of like a fast charger on 1/10 scale r/c... they can be used but not advisable to use it all the time, about the 3.6v li battery packs, try opening it's black plastic cover, this is a bit hard to do, because a very strong double sided tape holds the battery and the black hard casing together, then you'll see inside an electronic board connected to the li-ion battery, before removing the electronic board from the battery, note which point is connected to the + and - terminal of the li-ion, because this is where you will solder your charging jack, and the other side of the electronic board should be connected to the terminal output on the casing of the battery, identify which one is + and - , this is the part to be connected on the cellphone charger.
