No, it is desirable for a battery to have a low internal resistance.
The value of internal resistance of 1.5 volt battery is 0.5 ohms.
Internal resistance is approximately equal to 94.667
That will depend on the internal resistance of the battery. I = E / R Where I is the current, E is the open circuit battery voltage, and R is the internal resistance of the battery.
You have to imagine the internal resistance as being in parallel with any load you connect. You get the maximum possible current when the load is zero. In this case, just apply Ohm's Law. That is, divide the voltage by the internal resistance.

Yes
Yes, increasing temperature can cause the internal resistance of a battery to increase. This is because higher temperatures can lead to material degradation and changes in chemical reactions within the battery, which can ultimately result in higher internal resistance.

The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).
As it ages, its Kirchhoff virtual 'internal resistance' increases. Pictured this way, the practical effect is that the open-circuit voltage of a failing cell still measures good, but the voltage quickly sags when you try to draw any current from it
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.
Internal resistance equals external resistance when the load connected to a battery consumes power equal to that dissipated in the battery's internal resistance. This occurs when the open circuit voltage of the battery drops to zero.
