How Long Will The Battery Last With An Inverter? When calculating actual runtimes, constant power discharge tables are of great help, but even without them, one can approximate runtime using a few assumptions... Just be sure not to forget that these ARE the assumptions, while the constant power discharge tables are official data given by the battery manufacturer (and that may change without prior notice!). I would like to know how long … A 58.8 AH car battery with a direct DC connection to the light bulb (no inverter) and only discharging down to 50% should be able to power a single 12-volt, 3-watt LED light bulb for 117.6 hours and still be able to start the car. Doing so will shorten the life of the battery based on most battery manufacturers recommendations. 1000W ÷ 12V = … Anyway, here is the list of few more, very popular deep-cycle batteries that may be used as excellent inverter batteries, just be sure to dimension your battery pack properly: Constant power discharge characteristics of the WindyNation BAT-NSAP12-100 are given in the following chart (in watts, at 77°F/25°C): For example, WindyNation BAT-NSAP12-100 is able to power 1000W inverter for 30 minutes, but it will be discharged down to 10.5 volts, which is still acceptable for 1h discharge rate, but not as good as 10.8 volts of Renogy 12V 100Ah gel-cell battery. I plan to buy an inverter to power them. One good way of knowing the watt measurement is by multiplying volts by amps. Some people have gone to Lithium batteries that bring that power but they are not inexpensive. Small inverters Most car and marine batteries will provide great power for 30-60 minutes, even when the engine is inactivated.The real time can vary depending on the age and state of the battery, and the energy demand that is placed on it by the equipment ordered by the inverter. That means that if the inverter is rated at 1000 Watts, and its efficiency is 90%, it requires ~1100 watts of power: P (input watts) = P (output watts) / Efficiency = 1000 W / 0.90 = 1111.1 W. Now, in order to calculate how many Amps does a 1000 Watt inverter draw, we have to divide input power with input volts: I (Amps) = P (W) / U (V) = 1100 W / 12 V = 91.66 Amps, So, if we have 92 Ah deep cycle battery, it will be able to power 1000W inverter with 90% efficiency for 1h, right? 55ah at 9 amps is 6.1 hours.
