Can I replace my rechargeable battery with a 9v?

I have a Rex R3 (Odyssey o3x) which I haven't used in about 5 years, but the last time I used it I remember it didn't have very good battery life. I'm pretty sure it has a rechargeable 7.2V battery, so I want to know if I will be able to remove that and install a regular 9V battery so I don't have to bother with recharging.
If that wouldn't work, would it work if I bought a separate 7.2V rechargeable battery and replace it with that when the power runs out?

I would confirm what you have in there and replace it honestly. A 9v is almost two full volts higher then the 7.2v, assuming that's what it is, so while it may work you may burn our your board.

If a 9V is going to risk burning the board would it work just buying another 7.2V batter and charge it to use if the current battery runs out of power? I don't know if any of these are compatible or if they're the same size, maybe you know if they are:

I don't know what the MaH of the battery that came with the gun, or the dimensions of the battery, so I don't know which one of those to get.

mAh is the amount of milliamp hours the battery will last. Buy the highest you can find. It won't hurt your marker board

i have no expierence with that board, but:
the electronics (on most other boards) use regulated voltage (3.3v or 5.0v most commonly) and unregulated voltage is "only" used for the capacitor and solenoid.

the caps come in different falvors: 16v, 50v 100v ......
the solenoids are basically little coils with an actuating rod in it. the current creates a magnetic effect and moves the rod.
the solenoid gets an electric pulse from the cap which is way higher than 9v.

so i would try a 9v. i had an ape board running with 12v just fine ...
still: it's your own risk ;-)

The capacitor doesn't increase voltage that's sent to it. If you're supplying the board with 3v, the 9v capacitor doesn't mean voltage after the capacitor is 9v. Boards will only work with a range of voltage; it all depends on how the board was designed. You might be alright or you might fry your board. Personally, I wouldn't try it.
