The 12 amp hour battery will last longer under the same load as a 10 amp hour battery. For example if you had a load drawing 2 amps, the 12 Ahr battery would last 6 hours and the 10 Ahr would last 5 hours under ideal conditions.
There are ideal gases..
Two types of non-ideal solutions are ideal mixtures and non-ideal mixtures. Ideal mixtures follow Raoult's Law, where the vapor pressure of each component is directly proportional to its mole fraction in the solution. Non-ideal mixtures do not obey Raoult's Law due to interactions between the components, such as deviations from ideal behavior or the formation of new chemical species.
Under ideal conditions, population increases.
An ideal gas
The equivalent resistance you would have to place in series with an ideal battery (which of course does not exist) of the same voltage to get the same behavior (voltage drop with load) as the real battery has. It is a mathematical modeling technique to help in circuit analysis.
i like interstate batterys have them in both my cars
There is internal resistance in a battery because a battery is not an ideal voltage source. It may be close, but it is not ideal. As a result, analytically, there will be some series resistance, resistance which places a limit on the maximum current that the battery can provide. While no battery is ideal, most are sufficiently ideal to not require any consideration of the internal resistance. If your circuit is dependent on the internal resistance of a battery, then it is probably not well suited for that application.
Ideal is 14.2 volts 13.8 is acceptable
Sonic Alert SBP100 Sonic Boom Portable Vibrating Alarm has a long battery life and would be ideal for camping.

You need to do a parasitic draw test. Use a voltmeter to check base voltage of battery. Then crank the engine, check voltage at battery. It needs to be at least two more volts than previous base voltage. Then apply a load or turn on headlights. The voltage should not drop over one volt. Ideal base voltage at battery terminals is 12.6, ideal charging voltage would be 14.6, ideal loaded voltage would be 13.6 volts aproximately. If you find a drainage in system and you have a good battery, then you need to check radio and main accessories first, then check door latch switches and courtesy dome lamps.

A battery is a source that maintains a constant value of potential energy in its terminals. The chemical reactions within the battery create a potential difference between its terminals that remains constant as long as the battery is in good condition.
Any modern day car's ideal battery voltage is 13.8Volt. In practive however the voltage you'll find on a charged battery when testing will be in the region of 12.5V to 13V A fully charged battery will read 12.6 volts with the engine not running. With the engine running at idle speed it will read from 13.5 to 15.5 volts.
The current in a battery depends on the load connected to it. For an ideal 1.5V Alkaline battery with no load, the current would be very low due to the internal resistance of the battery. When a load is connected, the current will vary based on the resistance of the load according to Ohm's Law (I = V/R).
It really depends on what kind of battery, what kind of laptop, what kind of processor and what you do with your laptop. Typical reliable answer for most new 6 cell battery is 3 hours at least, and 9 cell battery last 4-5 hours.
It's all relative. A battery has internal resistance. Batteries are not "ideal" voltage sources. If there is a "heavy" load on the battery (low resistance), the voltage you measure on the outside of the battery will be lower. A car battery is normally thought of as a 12 volt battery. When there is no load (disconnected) you can often measure in excess of 13 volts if it's fully charged. During normal cranking of the engine, the voltage can drop below 11 volts.
