Safety First
Stop use when warning signs appear
Do not continue charging or operating a product that is smoking, swelling, sparking, leaking, severely overheated, physically damaged or producing an unusual smell. Keep people away from immediate danger and contact qualified assistance.
Do not open a battery enclosure, bypass protection, alter wiring or attempt an unapproved repair before claim review. This can increase risk and may affect evidence or coverage.
