car battery amp hours calculator

Often it is from 8 to 12 hours. Thats because an 800 W air conditioner on 240V requires fewer.

How Many Watts In A 12 Volt Battery Calculator Chart Learnmetrics

Battery Life Calculator This battery life calculator estimates how long a battery will last based on nominal battery capacity and the average current that a load is drawing from it.

. This calculator will tell you what battery size you need. Terms E Voltage Volt I Current Amp P Power Watt R Resistance Ohm. With a 12-Volt battery 41.

If you are having issues accessing your account please contact our Rates Application Group at 213 367-4709. I have this app application and I need it to run for X hours what size battery will I need. 84 Amps DC x 3 hours 252 AH.

This calculator is intended to help you calculate the power levels of your car audio or lighting systems. To power a 200W device for 5 hours you will need a battery with at least 8333 Ah. Our online calculator will help to calculate how much time needs for charging a car battery using a direct current.

Input these numbers into their respective fields of. You can compare the results to see the effect on the total duration of your trip. In this example we will take a standard 12 V battery.

Calculations in Amp-Hour To get 1000 Watts from a 48-Volt battery the battery has to provide about 21 Amps. Lets say its 264 Wh. Since watts amps volts divide the watt hours by the voltage of the battery to get amp.

Choose the amount of energy stored in the battery. In the Ah calculator above you just slide the wattage to 200 and the hours to 5. To calculate the driving time between two places start by entering the source and destination for which you want to calculate the driving time and then click on Calculate Travel Time which will.

The average time to charge a dead battery is 10 to 12 hours. The rule of the thumb for converting CCA to amp hours is divide the CCA by 725. The electricity cost per day in dollars is equal to the energy consumption E in kWh per day times the energy cost of 1 kWh in centskWh divided by 100 cents per dollar.

Travelmath provides an online travel time calculator to help you figure out flight and driving times. What size battery do I need. You get the result.

T is the duration in hours. The first charging of a new uncharged battery. Amp-hours watt-hours 12 volts 1470 12 1225 amp-hours at 12 voltsBy dividing the amp-hours by the battery voltage the amp-hours will alter if you use a different.

200 Ah Battery Life 200 Ah 333 A 60 hours As we can see because the amp draw is halved the battery life is increased. For example if your battery has 1500 CCA you need to divide it by 725 to get the predicted.
