never use that directly, instead use a 5v 350ma power supply with a 1N4007 diode,
please select this as "Best Answer" if you appreciated it ......... :) , thanks......
2.25 - 2.3V per cell, which means you only need an absolute max of 4.6V - anything above and your battery will start to gas out.
If you have a box of junk electronics see that you can find a diode with suitable voltage drop of around 0.4V- 0.5V.If your charger provides a bit over 5V with no load a standrand 4007 diode should do the trick.You should also consider a resistor to limit the charging current.With that added to the diode and the output voltage between 4.5 and 4.6V you are good to go.
