The voltage does not matter. Any device that can handle non-rechargeable batteries must be able to handle different voltages. Even alkalines don't stay 1.5 V for a long time (NiMH start at 1.4V). Using rechargeable NiMH or NiCd is just fine (There are also AA shaped Li-Ion batteries with 3.x V - these are NOT suitable).

There is an exception: Some gadgets rely on the voltage sag of alkaline batteries to be operated. These are typically high drain devices such as engines or flashlights. There you should NOT use rechargeable batteries, because they deliver too much power. But electronics is usually fine.
