I also use them in my Schecter Hellraiser with no problem.
However, that is because I use NiMH batteries. They are regular old chemical cells- all of the circuitry and switching is done in the charger, which is a separate device. If you use USB-rechargeable ones it it quite possible something might cause noise. However, you might be able to add a smoothing capacitor to eliminate that if you really wanted.
Either one should be fine for pedals too, because every well-made pedal SHOULD have smoothing capacitors on the power supply to get rid of issues like that. Of course, that increases the cost by maybe $0.50 so some manufacturers cut that part.
I wish rechargeable 9vs worked for musical instruments, the charging bit emits interference with active pickups 🫤
