A swollen battery does not present a safety issue. HP has worked closely with our battery cell suppliers and third-party industry experts to help minimize the potential for HP batteries to swell over time and to identify that swollen batteries are not a safety issue.
HP recommends that customers experiencing battery swelling discontinue use of the notebook until the battery can be replaced. Customers should contact HP to understand what battery replacement options are available.
If a battery is under warranty, HP will replace the battery per the terms and conditions of the HP Worldwide Limited Warranty or applicable HP Care Packs.
For batteries no longer under warranty, contact HP to purchase a genuine HP replacement battery.
