If the manufacturer only provides Watts drawn by the motor, we can convert this to amps by dividing against the voltage being used. These are common questions because they are very important in understanding how long to stay out on the water before heading back, and are fairly easy to answer if you have all the necessary information. Battery Life: I have a battery and I want to run an (app) application against it. Throw away how long will a battery last calculator, and l et’s see an actual case, 10 Ah battery delivering 1A, would last 10 hours. Both of these factors are explained in detail right below. With this information, just divide the amp hour rating on your battery by the amp draw of your motor. To determine how long a battery will last or how long your motor will run for, we must divide the amp hour rating on the battery against amps drawn by the motor. These can all play as variables in how long the battery will last. battery lasts, because less current is being drained from it. You have to be careful if you are using a 12V, 24V or 36V system as this can affect your calculations. Motors draw different amounts of current from the battery depending on the motor size and speed it is turning. This information should be provided by the manufacturer and should be readily available on the product listing or on a specification sheet for the motor. Also note that though that this calculator cannot be used as an exact battery life calculator but more as an estimator. For example, if we have a deep cycle battery that is rated for 50Ah and we are pairing it with a motor that draws 52 Amps at max speed, we would use the following equation: 50 amp hour / 52 amps drawn = .96 hours of runtime. Cold Cranking Amps (CCA) cannot be used to estimate how long a battery will last. This calculator will tell you what battery size you need. This battery life calculator calculates the battery life of a battery in a circuit. To determine a battery last and motor runtime, you will need to know the following information: The amperage draw of the motor and the Amp Hour rating on your battery.

Why is it important to know the C-rate or C-rating of a battery We try to supply the best reference available. Take your average monthly kWh use and enter it here.

It also gives you an idea of how long a device will run from a specific battery. This type of Lithium battery is engineered to provide a long service life (over 10 years) while also being safe, with a stable chemistry and sophisticated electronic protection features.

drawn in the circuit, the total amount of current being used.

So if a 5 Volt battery has 20 Watt Hour rating, and, it draws 2 Amp current, then the Watt delivered by Battery = 10 Watts ( 5 Volts x 2 Ampere). Example: 60.09 x 1000 / 14.8 = 4060 mAH (rounded down) Will a higher mAh battery rating negatively affect my laptop? This rating measures how long a battery can maintain a consistent amperage output. mAH rating of a battery. Kwh/mo. the amount of current being

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. The battery life is the amount of time, normally specified in hours, that a battery will last in a circuit.
