WebIt’s important to select a bulb which matches what your battery can put out. If the battery has too low a voltage, the current flowing through the bulb will be small and the bulb’s filament won’t get hot enough to visibly glow. If the battery has too high a voltage, so much current will flow that the filament will get too hot and vaporize. WebCalculating your run time based on a 12 volt deep cycle battery is as follows: 12 x (Battery capacity in Amp Hours) = Run Time in Hours (Load Power In Watts) So if you were calculating how long you could run a 100-watt TV from your 60 Ah battery, the calculation would be as follows: 12v x (60 Ah) = 6 hours (100 watts) flamethrower history ww1
