That completely depends on the voltage of the battery.The energy delivered by the battery and dissipated by the resistor in one minute will be[ 60 x (Voltage of the battery)2 / 21 ] joules
Most batteries used in watches are one and one half volts 1.5v]

To increase voltage output when using more then one battery connect the batteries in series.
A standard alkaline cell battery typically has a voltage of 1.5 volts. Other types of batteries, like lithium-ion cells, usually have a voltage of about 3.7 volts. The voltage can vary depending on the battery chemistry and design, with some specialized batteries having different voltage ratings. Always check the specifications for the specific battery type to confirm its voltage.
This is entirely dependent on the battery. You must consult the battery's documentation to find the right answer.
battery produces voltage by
A multimeter is an instrument that can be used to measure cell voltage in a lead-acid battery. By setting the multimeter to the appropriate voltage range, you can connect the probes to the battery terminals to obtain a direct reading of the voltage of the battery or individual cells. This helps assess the state of charge and overall health of the battery.
The measured voltage of a battery may not match the stated voltage due to internal resistance, temperature, or the age and condition of the battery. These factors can lead to voltage drops when the battery is in use.
The voltage of a battery with three cells connected in series is the sum of the individual cell voltages. If one cell is connected the wrong way round, the total voltage will be reduced by the voltage of that cell.
