● 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.
● Ensure any screws during the servicing of this product are not lost or misplaced, to prevent accidental
puncture or damage to the battery and other system components.
● If the battery gets stuck inside your computer as a result of swelling, do not try to release it as puncturing,
bending, or crushing a lithium-ion battery can be dangerous. In such an instance, contact Dell technical
support for assistance. See www.dell.com/contactdell.
