A 7ah battery will hold a 1amp draw for 7 hours. With a smaller draw it will last much longer. In this case more than 3 times longer.
1 amp / .3 amps(300mA) * 7 = 23.33 hours to fully discharged.

How long will a Battery of 7.4 Volts 700 Amp-Hour last?
The voltage doesn't enter into the issue.If the current draw of your battery-powered equipment is 1 Ampere, the battery will last 700 years.If your equipment draws 1/2 Ampere, the battery will last 1,400 hours.If your equipment draws 2 Amperes, the battery will last 350 hours.And so on.CorrectionA 700 AH battery will THEORETICALLY last 70 hours at 1 amp current draw. A 700 AH battery will THEORETICALLY last 140 hours at 1/2 amp current draw.A 700 AH battery will THEORETICALLY last 35 hours at 1/2 amp current draw.The theoretical capacity of a battery is always greater than the actual capacity; electrical energy is released in the form of heat inside the battery.
