Check the Battery

Dell Battery Diagnostics

Our support site provides multiple diagnostic tests that can be run on your system and output results or error codes that can be then used to identify failures or provide to technical support if warranty service is required. These tests can fulfil a support request online and issue an in-warranty replacement where applicable, or direct you to additional resources to replace your battery.
From our main support site navigate to the diagnostic section or click the link below.

• To run the test, browse to the Dell Battery Diagnostics. We will then connect to your system via Dell System Detect to run the test and if the test fails you can then log an in-warranty service call if applicable or have the option to purchase a new battery from the Dell Batteries and Adapters website.

If you have already used diagnostics in the past your information should be stored and you will be directed straight to the diagnostic test.

When the battery diagnostics fail, you can log a in warranty service call using the following link - Enhanced Preboot System Assessment. You will need to enter the Error and Validation code as seen on the screen, you will also need to enter the Service tag of the faulty computer, just follow the prompts to complete the process.

If your battery warranty has expired and the battery diagnostics fail, a new battery can be purchased at the Dell Batteries and Adapters website. Only Dell batteries should be used in Dell notebooks, and Dell batteries can only be purchased from Dell. A normal characteristic of a rechargeable battery is that its operating duration decreases over time.

The battery may eventually need to be replaced. Based on this characteristic, consumed batteries may not be covered under warranty.
