Default Switching from watch batteries to AAA

Simple question.

I have a simple laser pointer that i picked up at a pet store. 5mw 650+-10 class 111a

It runs off of 2 energizer 357/303 watch batteries with 165 mAH 1.55v. I want to switch over to AAAs so that i don't have to keep buying watch batteries.

Durecell's AAAs are rated at 1.5 volts. I was just wanted to know if I should worry about energy spikes or if 2 AAA can replace 2 of these watch batteries.

I even have a old burnt out laser pointer that runs off AAAs that i could use the casing from. Just seem to have different diodes.
