● 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.
● Always purchase genuine batteries from www.dell.com or authorized Dell partners and resellers.
● Swollen batteries should not be used and should be replaced and disposed properly. For guidelines on how to
