Only according to classical physics.

you can measure the differences in mass.)

Surely if you're storing energy you're not creating or destroying it?

Maybe, but it violates the conservation of mass.

You can store energy without converting it to mass.
Chemical (batteries), and mechanical (springs) methods store energy
without converting it to mass.

Phone call for you - some bloke called Albert...

Seriously - yes, there is a mass increase.

Seriously, no there isn't.
The energy is within the chemical bonds and doesn't require any extra
mass to hold it.
If you seriously think it increases the mass can you tell us which
subatomic particle it creates and how?



Er, no need fpor that. You tell me how teh sanem number of subatomic
partocles acquire mass as tehy reach towrads teh speed of light..

Any increase in molecular velocity as in e.g. a hot gas, acquires mass
with respect to the inertial frame against which those velocities exists.

A compound that has higher energy than its constituent atoms is heavier
by a very small amount, than what its made of. You can if you want talk
about kinetic energy of spinning electrons in valency shells, and mass
increase, that way, but the truth is classical models dont fit well in
the quantum world.
