It isn't. The size of a battery is governed primarily by how much current it is designed to provide, and for how long. A standard 6-volt lantern battery needs to provide a lot more current than a standard 9-volt transistor battery.

The size is a pretty good indication of the power available. The 9-volt battery produces a higher voltage, but the maximum current is a lot less. If you put a heavy load, like a flashlight bulb, on the 9v battery, the voltage will drop down to zero in a few minutes. The 6 volt battery could power it for an hour or more. To compare the power you can get from a battery, they have ratings in amp-hours, although it may be hard to find a figure for small batteries. If the rating is 1 amp-hour, it means the battery can supply 1 amp for an hour, or 1/2 amp for 2 hours, and so forth.

The power of electricity depends upon two things: voltage and amperage. If you compare the flow of electricity with the flow of water, voltage would be like the water pressure, amperage would be like how much water flowed out of the faucet per minute. How many glasses, for instance you could fill up in a minute. The voltage is determined by what the battery is made of, not it's size. Amperage, on the other hand is largely a function of size. Six volt batteries are made of chemicals which produce only one and one half volts. Therefore four cells each producing one and one half volts are connected together in one fairly bulky package to produce six volts. The nine volt battery being smaller tolerates less amperage (fills up fewer glasses) but is most often used in solid state electronic devices like calculators and radios which use less current (aren't very thirsty).

The 6-volt lantern battery has a lower voltage, but higher amperage. This means it contains more juice. If you were to hook up identical light bulbs to both the 9-volt and the 6-volt batteries, the one on the 9-volt would burn bright, but the one on the 6-volt would burn much, much longer.
It's kind of like drinking. The 9 volt battery is a airplane bottle of vodka, but the 6-volt is an entire keg of beer. Which will ultimately get you drunker?

The 6 volt battery is essentially a lantern battery - it is large to increase it's capacity and give a longer life in service. Since it is used primarily for a lantern, there is no need to design it small.
On the other hand, the 9 volt battery is primarily for electronic devices - they draw very little current for the most part and designing a smaller battery to easily fit in a smaller, portable device was more important than increasing its capacity.

It is just designed to provide more current or longer life. A 9 volt battery is actually a few small batteries connected in series to raise the voltage. The assembly is just encased in a squarish can.

The amps,ohms,watts are different in a six volt batt. than a nine volt. I thinks the six volt is good for long durations of low watt use,And the nine volt is good for devices the require shorts bursts of high wattage and lots of amps.
Someone help me out here
