Compatible HP Chromebook Models

This replacement battery fits HP Chromebook 15-de and X360 14-da devices. It matches OEM part numbers SY03XL and L29959-005 for direct compatibility. The 3-cell lithium-ion pack delivers 11.55V and 5011mAh capacity. It is a new component sourced from a USA-based supplier.

Buyers needing a direct SY03XL replacement

This unit suits owners of the listed Chromebook models whose original battery has degraded. It is not for users of other HP laptops or Chromebooks with different part numbers. Buyers requiring a higher capacity than 5011mAh should look at alternative options. The 6-month warranty covers early-life defects only.

Sustained discharge at rated voltage

The lithium-ion chemistry maintains a stable 11.55V output throughout the discharge cycle under typical workloads. Cell balancing across the 3-cell pack supports consistent runtime during extended use. Thermal behaviour remains within normal limits for this form factor. Capacity retention follows standard lithium-ion ageing characteristics over repeated cycles.
