Mar 18, 2023 · Assuming that you have a lead acid battery with a capacity of 12 volts and 100 amp hours, then a 100-watt bulb will run for approximately 20 hours. This is because the power consumption of the bulb is 100 watts / 12 volts = 8.3 amps. Therefore, the total number of amp hours used by the bulb over 20 hours is 8.3 x 20 = 166 amp hours.The formula above gives you the watt-hours or the power consumed by the car. Suppose you operate a 12V battery at 20 amperes. The watt-hours will be 240 Wh. Similarly, if you operate the same battery at 25 amperes, the watt hours will be 300 Wh. It is worth noting that a lot of car battery manuals mention average amp hour rating like this: 12V25 Feb 19, 2023 · Therefore, a 12 volt battery contains 144 Watt-hour or 144 Wh of energy. Here’s another example, a car has a 12v 105 Ah battery. According to the formula Wattage = Amps x Voltage. 1260W = 105A x 12V. It means that the car battery wattage is 1260 and can deliver 1260W of power for one hour. The car battery Amp hour is a measure of how much energy a car battery will deliver for 20 hours at standard temperature of 25°C without the voltage falling below 10.5 volts.
