CAUTION:
● Exercise caution when handling Lithium-ion batteries.
● Discharge the battery as much as possible before removing it from the system. This can be done by
disconnecting the AC adapter from the system to allow the battery to drain.
● 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 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
