How Long Will Car Battery Last Power Inverter. 12VDC 50AH 600 Watt Hours keep in mind a car battery is a starter battery not a deep-cycle battery and you will damage it by powering appliances for any length of time Inefficiencies of the car battery with inverter will be about 15 so. For example a 50AH battery will likely give you 50 hours of use if you only draw 1 amp per hour.
Applying the 95 inverter efficiency the run-time 045 hours or 13 minutes. Most automobile and marine batteries will provide an ample power supply for 30 to 60 minutes even when the engine is off. In other words 100ah 20hr 5 amp load for 20 hours.
A battery rated for 100 amp hours is usually rated for that capacity when discharged at a 20 hour rate.
Youve lost nearly 50 of the amp hours hours available by using 50 of the total amp hour capacity. Youve lost nearly 50 of the amp hours hours available by using 50 of the total amp hour capacity. As I stated before this is an estimate and each application varies. How long does a 12V battery last with an inverter.
