***Don't continue to use a damaged battery, as doing so is a potential safety hazard. If in doubt, replace it with a new battery.***
WARNING! To avoid personal injury and damage to the product:
● Do not puncture, twist, or crack the battery.
● Do not cause an external puncture or rupture to the battery. Punctures can cause a short inside
the battery, which can result in battery thermal runaway.
● Do not handle or touch the battery enclosure with sharp objects such as tweezers or pliers, which
might puncture the battery.
● Do not compress or squeeze the battery case with tools or heavy objects stacked on top of the
case. These actions can apply undue force to the battery.
● Do not touch the connectors with any metallic surface or object, such as metal tools, screws, or
coins, which can cause shorting across the connectors
WARNING! To reduce potential safety issues, use only the user-replaceable battery provided with the
computer, a replacement battery provided by HP, or a compatible battery purchased from HP.
IMPORTANT: Removing a battery that is the sole power source for the computer can cause loss of
information. To prevent loss of information, save your work or shut down the computer through
Windows before you remove the battery.
