Battery Life Solution

STEP 0: Pre-Calculation Summary

Formula Used

Battery Life = Battery Capacity/Battery Output Current
BL = C/I_o
This formula uses 3 Variables

Variables Used

Battery Life - (Measured in Second) - Battery Life list their reserve capacity, which describes the approximate time for which they can run without recharging, on the label or in the user's manual.
Battery Capacity - (Measured in Ampere Second) - Battery Capacity is defined as the total amount of electrical energy that can be stored in an array of electrochemical cells.
Battery Output Current - (Measured in Ampere) - Battery output current is defined as the total current supplied by the electrochemical battery to the load connected across it.

STEP 1: Convert Input(s) to Base Unit

Battery Capacity: 1000 Ampere Hour --> 3600000 Ampere Second (Check conversion here)
Battery Output Current: 0.5 Ampere --> 0.5 Ampere No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BL = C/I_o --> 3600000/0.5

Evaluating ... ...

BL = 7200000

STEP 3: Convert Result to Output's Unit

7200000 Second -->120000 Minute (Check conversion here)

FINAL ANSWER

120000 Minute <-- Battery Life

(Calculation completed in 00.020 seconds)

< 6 Battery Life Calculators

Battery Life given Voltage and Power

Go Battery Life in Hours = (Battery Capacity*Voltage)/(Output Power)

Battery Life in Months

Go Battery Life in Months = Battery Capacity/(30*Battery Output Current)

Battery Life in Years

Go Battery Life in Years = Battery Capacity/(365*Battery Output Current)

Battery Life in Days

Go Battery Life in Days = Battery Capacity/(24*Battery Output Current)

Battery Life

Go Battery Life = Battery Capacity/Battery Output Current

Battery Charging Time

Go Battery Charging Time = Battery Capacity/Load Current

Battery Life Formula

Battery Life = Battery Capacity/Battery Output Current
BL = C/I_o

What is the capacity of battery?

The Capacity of your battery provide info about how long your battery will provide energy to your device and measured in ampere hours. You can usually find this value printed on your battery.

Define Power Consumption of Battery?

Consumption is the average current draw of your electronic device, expressed in amperes or miliamperes.

How to Calculate Battery Life?

Battery Life calculator uses Battery Life = Battery Capacity/Battery Output Current to calculate the Battery Life, Battery Life estimates how long a battery will last, based on nominal battery capacity and the average current that a load is drawing from it. Battery capacity is typically measured in Amp-hours (Ah) or milliamp-hours (mAh), although Watt-hours (Wh) is occasionally used. Battery Life is denoted by BL symbol.

How to calculate Battery Life using this online calculator? To use this online calculator for Battery Life, enter Battery Capacity (C) & Battery Output Current (I_o) and hit the calculate button. Here is how the Battery Life calculation can be explained with given input values -> 2000 = 3600000/0.5.

FAQ

What is Battery Life?

Battery Life estimates how long a battery will last, based on nominal battery capacity and the average current that a load is drawing from it. Battery capacity is typically measured in Amp-hours (Ah) or milliamp-hours (mAh), although Watt-hours (Wh) is occasionally used and is represented as BL = C/I_o or Battery Life = Battery Capacity/Battery Output Current. Battery Capacity is defined as the total amount of electrical energy that can be stored in an array of electrochemical cells & Battery output current is defined as the total current supplied by the electrochemical battery to the load connected across it.

How to calculate Battery Life?

Battery Life estimates how long a battery will last, based on nominal battery capacity and the average current that a load is drawing from it. Battery capacity is typically measured in Amp-hours (Ah) or milliamp-hours (mAh), although Watt-hours (Wh) is occasionally used is calculated using Battery Life = Battery Capacity/Battery Output Current. To calculate Battery Life, you need Battery Capacity (C) & Battery Output Current (I_o). With our tool, you need to enter the respective value for Battery Capacity & Battery Output Current and hit the calculate button.
