Dell KNM09 7CJRC battery – Frequently Asked Questions

What are the Guidelines for Handling and Replacing the Battery on a Dell laptop?

Like most laptops, Dell laptops use lithium-ion batteries. One type of lithium-ion battery is the lithium-ion polymer battery. Lithium-ion polymer batteries have increased in popularity in recent years and have become standard in the electronics industry due to customer preferences for a slim form factor (especially with newer ultra-thin laptops) and long battery life. Inherent to lithium-ion polymer battery technology is the potential for swelling of the battery cells.

Swollen battery may impact the performance of the laptop. To prevent possible further damage to the device enclosure or internal components leading to malfunction, discontinue the use of the laptop and discharge it by disconnecting the AC adapter and letting the battery drain.

Swollen batteries should not be used and should be replaced and disposed of properly. We recommend contacting Dell product support for options to replace a swollen battery under the terms of the applicable warranty or service contract, including options for replacement by a Dell authorized service technician.

For more information, refer to Dell Knowledge Base article Swollen Battery Information and Guidance

• Exercise caution when handling Lithium-ion batteries.
• Discharge the battery before removing it from the system.
  To discharge the battery, unplug AC adapter from the system and operate the system only on battery power.
  When the system will no longer power on when the power button is pressed, the battery is discharged.
• Do not crush, drop, mutilate, or penetrate the battery with foreign objects.
• Do not expose the battery to high temperatures, or disassemble battery packs and cells.
• Do not apply pressure to the surface of the battery.
• Do not bend the battery.
• Do not use tools of any kind to pry on or against the battery.
• If a battery gets stuck in a device as a result of swelling, do not try to free it as puncturing, bending, or crushing a battery can be dangerous.
  Contact Dell product support for assistance and further instructions.
• Using a non-Dell or incompatible battery may increase the risk of fire or explosion. Replace the battery only with a compatible battery purchased from Dell that is designed to work with your Dell computer. Do not use a battery from other computers with your computer. Always purchase genuine batteries from https://www.dell.com or otherwise directly from Dell.

What are the Recommended Guidelines for Storing a Dell Battery Over a Long Period of Time?

When storing for more than 4 days these guidelines can better preserve the life of your battery:

• Do not store batteries for long periods plugged into or attached to any power source. This includes AC adapters, and laptop security carts plugged into an outlet.
• Laptop batteries, including those stored in laptop systems, should maintain an Operational Storage Temperature of 0° to 35°C (32° to 95°F).
• Batteries may be stored in the laptop or outside of the laptop.
• Charge batteries before storing. The recommended charging time should not exceed 1 hour. Typically, this should charge the battery to between 80% and 100%. (Some discharge will take place over time. Stored batteries are expected to discharge 10-15% over a four month period, for your information).

How do I Check the Battery Health Status on a Dell laptop?

On Dell laptops, battery health status can be checked, both outside and inside the operating system environment. The battery health status indicates the current state of the battery performance and allows you to decide if the battery requires a replacement. Battery health can be checked using:

• BIOS
• Hardware diagnostics Notes:
  • Dell offers an online battery diagnostics test, to run it browse to the Online Battery Diagnostics page.
  • The test will start automatically.
  • You may be prompted to install or update the SupportAssist program, if so, follow the prompts.
• Dell utilities:
  • Dell Power Manager – supported on Dell Inspiron, Vostro, and XPS laptops running Windows 10
  • Dell Command | Power Manager – supported on select Dell Latitude and Precision mobile workstations

How Long Does a Dell Laptop Battery Last? When Should I Consider Replacing the Battery?

All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade.

For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced within 18 months. We recommend buying a new Dell laptop battery when the run time does not meet your needs.
