The Charger output is 12v 1200mah, and I want to charge a 9.6 NI-MH 3500mah battery pack. If I'm able to charge the pack could you tell me how long it would take to charge. Could I also charge 8.4 volt NI-CAD/NI-MH battery packs with it?

Can you use it, yes you can should you do it no you shouldn't. The voltage would not be too much of a problem if it was regulated but more likely it isn't at this current it would take a little less then 3 hours to charge the pack but 1200 is a lot to put into a AA-cell (the cells used to make 9.6 volt battery packs) and 12 volts unregulated is more like 13.7 to 14 volts. If the battery gets internally to hot it will explode. A 9.6 volt charger is available at radio shack for about 10 dollars I would just do that if I were you. 3500mah/1200ma=charging time.

the correct charger will be able to monitor the charge and charge at different rates depending on the state of the battery. when it reaches 90% charge it goes into a maintenance charge mode to top it off.
in a pinch u could probably use that, if u have a way to monitor it and aren't looking to get a perfect full charge.
for regular charging get the right charger.

NI-MH batteries should be charged with the correct charger if you want them to not become damaged and to charge properly.
