Not correct. As the voltage of the battery drops, the current will drop also.
Ohm's law: current = voltage/resistance. As voltage decreases, current decreases proportionally. (half the voltage, half the current)

As voltage and current decrease, power (watts) decrease dramatically. Thus half the voltage, which results in half the current, means the power is one fourth of what it was.
