The voltage wont be right. Those are 3 volts per cell where as a standard AAA is 1.5 volts. You could potentially damage your electronics by using these.

Sorry, no -- the battery shown here has 6 x 1.5v AAAA cells. They will work where an AAA is expected, but have much smaller capacity, so will run out quicker.

Are you thinking of 3 x 3v lithium cells? Also 9v.

Other designs of PP3 battery have a stack of 6 rectangular-but-rounded flat cells that are no use at all in this application :)

Those are actually AAAA (Quad-A) batteries.

Those are not AAA batteries. They are AAAA that goes into AAA holders but with less juice. Also, some batteries (mostly cheap ones, but is not restricted to) are really made of stacks of metal and acid contained in plastic wrapping. So, only some works and take precaution and preparation for disappointment when you try this at home.
