Enter the voltage (volts), the current (amps), and the time (hours) into the calculator to determine the Battery Energy. 

Battery Energy Formula

The following equation is used to calculate the Battery Energy.

BE = V*I*T *3600

  • Where BE is the Battery Energy (Joules)
  • V is the voltage (volts) 
  • I is the current (amps) 
  • T is the time (hours) 

How to Calculate Battery Energy?

The following example problems outline the steps and information needed to calculate the Battery Energy.

Example Problem #1

  1. First, determine the voltage (volts). In this example, the voltage (volts) is determined to be 3 .
  2. Next, determine the current (amps). For this problem, the current (amps) is measured to be 4 .
  3. Next, determine the time (hours). In this case, the time (hours) is found to be 5.
  4. Finally, calculate the Battery Energy using the formula above: 

BE = V*I*T *3600

Inserting the values from above and solving the equation yields: 

BE = 3*4*5 *3600 = 216000 (Joules)


Example Problem #2

Using the same method as above, first, we need to measure or determine the variables required by the equation. For this example problem, these are provided as follows: 

voltage (volts) = 6

current (amps) = 9

time (hours) = 8

Enter these given values into the calculator or above yields: 

BE = 6*9*8 *3600 = 1555200 (Joules)
