This question has to do with this question regarding the size of a battery. For instance the AA battery is larger than the AAA battery. Here is the link to that.

Can you use an extra large battery (such as a lantern battery) with 1.5volts to take the place of a AAA 1.5volt battery? Of course, you may have to use a stepdown transformer if the lantern batter carries more than 1.5volts. Perhaps a resistor would do the trick. I don't know.
But, to put it more simply. Could a AA size battery with 1.5volts take the place of a AAA battery with 1.5volts?

The general answer is "yes." If the battery is rated at a certain voltage, the size of a battery does not matter. In general, the physical size of the battery is proportional to the power capacity of the battery, which is stated in amp-hours. If you can find a 1-1/2 volt battery of any larger size, and you can gain access to the wiring that connects the battery compartment to the internal circuitry of your gadget, you can hook them up and power the gadget with the larger battery for a longer time.
As far as I know, there are no 1.5 volt lantern batteries available any more. If you want to power your gadget from a 6 volt or 12 volt lantern battery, you will have to use a DC-to-DC voltage converter, which is another gadget. You cannot use a step-down transformer, because transformers work only with AC current. If you connect the primary windings of a transformer to a large battery, it will quickly get too hot to touch, and can actually melt or start a fire. So be careful until you find out what you are doing. But go ahead. Good luck.
P.S., you can use a resistor to reduce a DC voltage. You have to know how much current your gadget draws, and then use the voltage-divider equation to calculate the required resistance. You can search for "voltage divider" on the internet.
Have fun.

Other than the fact that it wouldn't fit in the socket, a D, C, or AA can replace an AA. The only difference would be how long the battery lasts, with the D-cell lasting the longest, because it has the highest capacity, followed by the C, then AA, then AAA.
The size allows the manufacturer to pack more chemical and more electrodes in to the battery

In terms of voltage output; a cell is a cell is a cell. Physical size maybe a limiting factor. Any single battery cell voltage output will be identicle as long the electolysis is produced by the identicle materials; regardless of size(ie..NiCad, Lead Acid ect..). Potential output power (current) is determined by the volume of electrolysis; reflected in the physical size of the battery. Total voltage output is determined by the number of cells in series.

Absolutely.
As long as the voltage is the same, there's no problem.
You could also put several aaa batteries in parallel, and again, no problem - just a lot longer life.

sure, as long as the resistance and amperage are the same.
( not likely )
also , size and contact area and placement.
