Battery History View is a freely downloadable application for Windows 10 / 11 that can be used to get the battery history information that is stored on the SRUDB.dat database of Windows.

All laptops are equipped with a battery that is charged using an AC adapter that is connected to the power port of your device. Depending upon your laptop usage and the capacity of the battery it can last from 4 to 7 hours on an average.

On a PC that is running Windows 10 / 11  charge / discharge cycle data is recorded in a file named SRUDB.dat located in C:\Windows\System32\SRU\. Apart from the battery, other System Resource parameters are also stored in this file.

Battery History View accesses SRUDB.dat and locates and displays all the information related to the laptop battery including:

  1. Full Charged Capacity
  2. Charge Percent
  3. Timestamp
  4. Charge Level
  5. Active AC Time
  6. Cycle Count
  7. CS Energy
  8. CS DC Time
  9. Designed Capacity
  10. CS AC Time
  11. Active Discharge Time
  12. Active Energy
  13. Active DC Time
  14. CS Discharge Time

The application is portable (no installation required) and must be launched using Administrator privileges. No sooner than it executes, it starts to fetch the laptop battery history from the SRUDB database. You can use it to extract the battery history from your local system as well as a remote system on your network provided you have access to it. The same data that is displayed can also be exported to various formats such as TXT, HTML, JSON, CSV and more.

How it Works:

1. Use the link at the end of the article to download the portable application. Extract the package and run the application as an Administrator. If you start the application as a normal user, it will automatically prompt to connect as an Administrator.

2. Battery History View will now access the local SRUDB database and display the complete information stored in it.
