$begingroup$ This rule of thumb is problematic as a 12V lead-acid battery is actually 6x2V cells in series. If a 2V cell of a particular size was able to be charged at, say 0.5A, six of them in series (six times the capacity) should also be charged at 0.5A. Voltage and power will need to be higher but the current should be identical.

But a Lead Acid battery dips below 12V at just under 50% capacity. So a 12V motor, like the fan, will simply slow down if it''s getting less than its “nominal voltage.” As it slows, it slows the rate of discharge on the battery until it''s simply turning like an unenthusiastic sign spinner at a sleepy intersection.
Low levels can lead to sulfation and reduced battery life. Regularly check levels and use distilled water as needed. Corrosion is another important factor to control.

The voltage of a lead acid battery decreases under load, which means that the voltage will be lower when the battery is powering a device than when it is not. The amount of voltage drop depends on the load and the capacity of the battery. What is the critical low voltage threshold for a lead acid battery?
The state of charge (SOC) of a lead acid battery refers to the amount of charge remaining in the battery. The SOC of a lead acid battery can be determined by measuring its voltage using a multimeter or other device. As the battery discharges, its voltage level decreases. Conversely, as the battery is charged, its voltage level increases.
For example, a 12-volt lead acid battery has a nominal voltage of 12 volts. However, the actual voltage of a lead acid battery can vary depending on its state of charge, temperature, and other factors. The state of charge (SOC) of a lead acid battery refers to the amount of charge remaining in the battery.
