Can you use a 9.6V battery where a 7.2V battery should be?

I am considering getting this
http://www.radioshack.ca/estore/Product.aspx?language=en-CA&product=6004330&category=R%2fC+Vehicles&catalog=RadioShack
and would i be able to use a 9.6V battery 1800mAh?
The truck is supposed to take a 7.2V. I have about six 9.6V and I do not
want to spent $45 for a 7.2V if I could use what I already have. It is
digital proportional which would be the first r/c of mine to have this. It
has independant front and rear suspension.(I've seen the truck in RS)
I would make the wire longer and strap the battery into the bed of the truck
and run it underneath and into the battery compartment to connect it(I
believe they take the same connector)

It is a 4wd radio shack truck for 90 bucks Canadian. I worked out the speed
to about 22 kph. I will eventually get a "real" rc truck one day(plan to
spend about 500 bucks) but for now i think this will do fine for how I
would use it.(Backyard bashing etc)

Would this make the truck faster? Would this burn out the electronics?

Thanks for the help, I may pick this up tommorow.

Now that I think about it, I have added more battery volts to r/c cars
before. I have this toyr'rus truck that takes a 9.6V. I joined a 9.6V and
a 4.8V together and hooked it up to the truck. The truck drove a lot
faster. I used it about 5 or 6 times like that. The truck still works
today with a normal 9.6V battery.

I used that same 4.8V battery in a 3.0V tyco canned heat truckbout 4 times.
That thing did wheelies on the carpet from a standstill, but it was to hard
to control because it just went too fast and tipped when you would turn.
Good for drag racing though. The canned heat still works fine on 2 regular
AA batteries today.

I have a fix somewhat for my tires. I'm going to convert the shafts so they
have Tamiya hubs on all for.

So, now I need to know, what rims out there will fir this setup? I know
that the Blackfoot rears do, but are there any 2.5" rims?

Without knowing anything about the motor and electronic radioshack use
in this truck, but increasing the voltage by 30% is to stretch th
limit. So these are the basic scenarios:
1) you might fry the electronics (you'll know immediately).
2) the truck might work fine (and runs faster with the increase
voltage)
3) the truck works fine for a while but the high voltage may shorte
the life on the engine.

However, the 9.6V batteries (you probably use) loose voltage quit
rapidly so as long as the truck still operates after 3 minutes I thin
you're ok
