can i use AA batteries in a device that usually uses a AAA battery?

[Lol]

my moms keyboard uses 4 AAA batteries, and im sick of changing them every month. i have a lot of AA rechargeables.

AAA batteries are 1.5 volts. i have NiMH AA batteries. they are 1.2 volts

can i cut out the wires and tape the AA batteries inside?

will that work? or will i fry my moms keyboard?
