Verify Model and Part Number Before Ordering

Confirm the exact model suffix printed on your laptop base or in the BIOS matches the supported list such as 14-ba011dx, 14-ba013dx, 14-ba015dx, 14-ba114dx, 14-ba253cl, 14-ba125cl, 14-ba175nr or 14-ba051cl.

With a 41.7Wh rating the cell provides consistent runtime rather than a brief peak followed by voltage sag. Safety certifications including CE, FCC and RoHS confirm the pack meets regulatory limits for sustained operation.
