mAh Battery Life Calculator is an online tool used in electrical engineering to precisely calculate battery life. Generally, battery life is calculated based on the current rating in milli Ampere per Hour and it is abbreviated as mAh. Ampere is an electrical unit used to measure the current flow towards the load.

The electric charge Q (mAh) in milliamp-hours (mAh) is equal to 1000 times the energy E (Wh) in watt-hours (Wh) divided by the voltage V (V) in volts (V): Convert mAh (milliamphours) to time in hours To calculate how many hours a certain mAh lasts, you need to know either the current , or the voltage and watts : First, fill in this box with your mAh : For example, if you have 1500 mWh and a voltage of 5V, the number of mAh is 1500Wh / 5V = 300mAh. Convert mAh to mWh Insert milliamp hours (mAh) and voltage (V) and click on Calculate to obtain milliwatt-hours (mWh). mAh ( milliAmp hours) is used to refer to battery capacity, or how much current a battery can source for one hour. For example a Cr2032 coin cell is typically rated at around 250 mAh. Online math solver with free step by step solutions to algebra, calculus, and other math problems.

Power Consumption in mA/h Calculator Use this simple online calculator to calculate the average current consumption of an electronic appliance or a circuit. This can be achieved by knowing the battery capacity of the appliance and the estimated hours for which power is consumed. You can also use; (Wh) = mAh x V / 1000 which abbreviates the formula utilized by the calculator in executing the conversions from milliamp-hours to watt-hours. For example, If you have 150 mAh and 45 V the calculation will be; (Wh) = 150 x 45 / 1000 = 6.75 (Wh) The online calculators have proved to be efficient in performing different conversions within a short period. Q (mAh) = 1000 x E (Wh) / V (V) = 1000 x 200 / 100 = 2000 milliamp-hours (mAh) This calculator has been programmed to offer speed and accuracy when converting the watt hours to milliamp hours. It is important to feed in the right values since the output depends on … Use our algebra calculator at home with the MathPapa website, or on the go with MathPapa mobile app. Great app!

To calculate how many hours a certain mAh lasts, you need to know either the current, or the voltage and watts: First, fill in this box with your mAh: mAh. Convert mWh to mAh (milliwatt-hours to milliamp-hours) Insert mWh and voltage (V) and click on Calculate to obtain milliamp-hours (mAh). Formula is (mWh)/ (V) = (mAh). For example, if you have 1500 mWh and a voltage of 5V, the number of mAh is 1500Wh / 5V = 300mAh.

Get your battery charger and find its charge current. It is the value ending with mA (milliampere) or A (ampere). Example 1 Battery charger has 4 AAA battery bays. On the charger there is a label with the following information: Min 90mA - Max 145mA Which means: Charging 1 AAA battery = 90 mA Charging 2 AAA batteries = 90 mA + 1/3 * (145-90
This can be achieved by knowing the battery capacity of the appliance and the estimated hours for which power is consumed. 4-20 Ma Definition. This 4-20 mA calculator is used to calculate the original measurement of overall vibration (or other physical pressure) units, as determined by the user or type of transducer, using the output current of the 4-20 mA transducer as well as the minimum and maximum of the unit range for the device.

An ampere hour or amp hour (symbol: A⋅h or A h; often also unofficially denoted as Ah) is a unit of electric charge, having dimensions of electric current multiplied by time, equal to the charge transferred by a steady current of one ampere flowing for one hour, or 3,600 coulombs.. The commonly seen milliampere hour (symbol: mA⋅h, mA h, or unofficially mAh) is one-thousandth of an ampere
A unit to measure the current flow is called as the ampere, also termed as amp. 1 Ampere is equal to 1000 mA. This online calculator is used to find the power consumption from the battery capacity in mA/h and estimated hours. Enter the electric charge in milliamp-hours (mAh), then press the Calculate button to get the result in amp-hours (Ah). mAh to Ah calculation Q(Ah) = Q(mAh) / 1000 The electric charge Q in amp-hours (Ah) is equal to the electric charge Q in milliamp-hour (mAh), divided by 1000. It’s quite simple, we just need to plug it into a 1000 mAh discharge of supply and calculate the time when it gets completely discharged. The basic formula for the calculation of mAh is done as below: mAh= Amount of time battery lasts x Amperes of the Discharge current.
