Actual voltage is a function of current drawn from the battery because at high currents, this effect is larger. Also, the actual voltage is a function of temperature because ions move faster at higher temperatures, so there is less internal resistance at higher temperatures [128, p. 3.9]. However, at higher temperatures, chemical reactions may occur more quickly, so the life of the batteries ...
