I just had a peek in my o2 (JDS Labs) I got with the batteries option, I can't open it up because the volume knob retainer screw isn't metric. There are two 9v 200 mAh rechargeable batteries that look like they are these ones I have linked above.
I use these rechargeables in mine without any issues.
They last a good while too. Pretty good investment.
