A CR1216 battery typically has a capacity of around 40 mAh, but its output current in milliamps (mA) can vary depending on the specific application and load. Generally, these batteries can deliver a current of about 5 to 20 mA for short periods, but for continuous use, the current draw should be lower to avoid rapid depletion. Always refer to the manufacturer's specifications for precise details on current output and capacity.
A good AA battery has about 1.5 volts across it.

There is not enough information given to answer the question. It would depend on the battery or other source that you get the 12.7 volts from.
Half of what they should - assuming they're all equally bad.
we use cell for many electrical apliances such as to start a toy car ,in torch to produce light,in telivision remot etc.
It depends on how many mah your charger can produce
I will assume you are serious. It doesn't produce volts. It simply limits them. It should allow up to 14.3 or so and shut off when the battery is fully charged.
If you add more batteries in series, the voltage would increase. This would drastically change the circuit. Normally this should also produce more current.The effect of adding more batteries in parallel is insignificant for many circuits. Adding more batteries in parallel is like lowering a battery's internal resistance - which, for many circuits, can be neglected.Example: The battery's internal resistance can be neglected; the battery gives a voltage of 12 volt, you connect it to a resistance of 2 ohm. According to Ohm's law, that will give you a current of 6 ampere. Note that the battery capacity does not enter the calculation! Adding a second battery (of the same kind) will produce the same voltage, thus, the same current.If you add more batteries in series, the voltage would increase. This would drastically change the circuit. Normally this should also produce more current.The effect of adding more batteries in parallel is insignificant for many circuits.

A 3 volt battery is a type of battery that produces a voltage of 3 volts. It is commonly used in various electronic devices such as remote controls, toys, and small gadgets. The most common types of 3 volt batteries are coin cell batteries and AAA or AA batteries.
A battery doesn't make any watts by itself, it has to be hooked up to a load first. And even something as tiny as an AAA battery can put out some decent watts for a brief moment if hooked up to something that'll pull a lot of amps - like a short circuit.
There are lots and types of battery
