The power output on a car battery will depend on how many cells the battery has. Each cell puts out 2.1 volts.
About 8000-19500 mAh at 1.5V

The energy delivered by a battery would depend on-- the battery's voltage-- the resistance of the load connected across its output terminals-- the length of the time the load is connectedThe power delivered by the battery is [ (voltage)2 divided by (load resistance) ].The total energy delivered by the battery is [ (power) multiplied by (time the load is connected) ].
Neither, it is a power source providing the energy to make the device work.
This is the main output from the alternator. It charges the battery and maintains power to the rest of the car's circuitry.
Heavy weight, power loss when converting the DC output to AC output, temperature limits, toxic substances in battery construction/disposal.
You can replace a Panasonic NiMH (Nickel-Metal Hydride) battery with a similar Duracell NiMH battery of the same size and with the same voltage and power output.
The battery charger can be used but it is not recommended. The battery charger does not have filtering on the its output like a power supply does. You will probably hear an AC ripple on the amplifier which will become very annoying when listening to the amplifier.
The usual reason for wanting three phase power is because of a large power requirement. Batteries are unsuitable for this. For lower power A.C. applications a battery can be used to supply an inverter which gives a single phase output.
An alkaline battery's output is DC as is any battery.
Take out the old battery and buy a new one that is the same - size, power output, and matching serial numbers. Most shops that sell watches will replace the battery for you.
If you do work on an object in half the your power output is
