We provided the meaning of battery life, example questions on it for a better understanding. The battery life can be calculated from the input current rating of the battery and the heap current of the circuit. Battery Life Calculator - You can use Utmel's battery life calculator to estimate the battery life of your devices based on battery capacity and system usage. If you know how much power your application takes to run, and the time you would like to run it, we'll recommend a 12-volt battery. You can target the Engineering ToolBox by using AdWords Managed Placements. I hope you understand it more clearly. The car battery stores power and then gives a zap of it to each of your cars electrical components. It gives the approximate battery runtime by taking the capacity of the battery, load current details. All you need to do is enter the voltage and capacity of your planned battery pack as well as your average power consumption to calculate the battery life. We have also built a free, simple calculator on our website where you can estimate the runtime of a battery as well as the required capacity. Consumption: The average current draw of the electronic device, expressed in amperes. It does not only power these electrical components, the battery also keeps the cars electrical current steady. It uses the formula mentioned above: E = V Q. Q = E / V = 26.4 / 12 = 2.2 Ah. To know how long you will charge your car battery or if your car battery already needs some charging, there are some factors you need to consider. Cash Cars Buyer Does! Learn More. This value is printed on your battery. Car batteries can usually be charged at a rate of 2 amps, 4, 6, 8, 10, 12, 20, 30, 40, and 50 amps.

The calculator assumes that the stress temperature, T2, is +110C (+383K). Cash For Junk Cars No Title No Keys: Instant Offer For Your Car Or Truck! But, you need to remember that car batteries have some limitations when it comes to their charging speed. When this happens, you need to have your car battery checked immediately. Necessary cookies are absolutely essential for the website to function properly. All Rights Reserved. Let you have a battery so that, the battery Capacity(in Ah) is approx. The backup time in years with self-discharge calculations is done using an Arrhenius model: The time to 1% fail (TTF) hours and activation energy, EA, have been estimated from accelerated life testing. Battery Run Time Calculator: Know how long will your battery run by taking the help of this calculator. We use batteries to power our circuits. For additional information you may view the cookie details. The formula to compute the battery life is here. t = Actual time to discharge the battery (i.e. So, the formula is given below. If you do a visual inspection on your car battery and you see a white, ashy substance on its metal, it is an obvious sign of corrosion. So, by using those principles or methods we make a useful battery life calculator only for you. It is known that the more power you are supplying your car battery at a certain time, the quicker it will charge. Electrical - Electrical units, amps and electrical wiring, wire gauge and AWG, electrical formulas and motors. So, this is the simple formula to find the battery life calculation. Support our efforts to make even more engineering content. Divide the battery capacity by the load current. But this is not enough because we dont know the backend functionality behind the battery life calculator. The simple steps to calculate the battery life is to enter the capacity of the battery, load current details in the given input fields of the calculator. Split Keyboard. It is mandatory to procure user consent prior to running these cookies on your website. Whatever the weather condition is when you are driving, maintaining your battery properly can help prolong its life. For example battery mAh, which is often incorrectly advertised higher than it's actual capacity. Multiply the result by 0.707 to get the battery life value. If the exponent constant k was one, the delivered capacity would be independent of the current. This calculator determines timekeeping operation time based upon battery capacity and load. The output of this calculator is an estimate, not a guarantee. Battery rumtime = capacity/consumption * (1 - discharge safety) Where, Capacity is the capacity of your battery in ampere hours. A battery rated at 36 V and 10.4 Ah will have a 417.6 Wh capacity (36 x 10.4 = 374.4), like on the Eunorau UHVO All-Terrain Ebike. A Premier Farnell Company Premier Farnell Limited. Now sometimes you do not know about the current of the battery. A car batterys lifespan will depend on several factors such as the type of battery you buy, its usage, the type of vehicle you drive, how you drive, and the weather conditions it is driven in. So for example, in this circuit we calculate a demand of 19 milliamps and the battery has a capacity of 3000 milliamp hours, so 3000 divided by 19 gives us 157.9 hours. Terms of Use. Transistor capacitor circuit design guide, AC Electrical Generator Basics- How Electricity is Generated, Properties of Carbon Dioxide at atmospheric pressure, Design and Build a PCB- SMD Circuit Board Design. The battery life equals the capacity in milliamp hours divided by the circuit current in milliamps. Since a car battery powers all of your cars electronics, when it loses its charge or is dying, you will notice that your cars electrical components will struggle to run on full power. Rosemount 3051S MultiVariable Wireless Pressure Transmitter. Default settings were used for these calculations. There are lots of other things that affect this, such as the age and the temperature.
