no, a 9 volt battery is small (goes in a smoke detector) a 9.6 volt battery is much larger, and it is not a DC battery (direct current) but NiCd (nickel cadmium.) two totally different things.

Yes they do make 9 volt batteries that are rechargeable. There is the Energizer Recharge, NiMH and the HiTech brand carries 4 types of rechargeable 9 volt batteries.
Yes, a 9 volt 1600 mA AC adapter can be substituted for a 9 volt 300 mA adapter. The mA number represents the highest allowable current to be drawn from the adaptor. The adaptor that you want to replace has only 300 mA maximum capacity. The new adaptor has five time the capacity of the old one which means that devices that draw up to 1600 mA can be connected to it. Depends on what you are pluging into.. if could possible run unit hot..
Using a 10 volt power supply for a 9 volt keyboard is not a good idea. The higher voltage will cause damage to the keyboard, burning it out and making it useless.
