Replacement battery for HP Chromebook 15-DE

This 3-cell lithium-ion pack replaces OEM part numbers SY03XL, L29959-005, L29913-2C1, HSTNN-DB8X and SY03060XL-PL. It fits the HP Chromebook 15-DE, 14-DA and X360 14-DA convertible models listed in the compatibility data. The unit ships new and carries CE, FCC and RoHS safety certifications.

Sustained output at 11.55 V and 60.9 Wh

Rated capacity is 5273 mAh at 11.55 volts, giving 60.9 watt-hours of energy for extended unplugged sessions. The three-cell layout delivers stable current under continuous load with low self-discharge when the notebook is idle. Built-in circuit protection guards against over-charge, over-discharge and short-circuit conditions during daily cycling.

Black hard-shell casing with OEM connector

The black enclosure matches the original chassis colour and uses the factory keyed connector for a direct, tool-free swap. No adapter cables or soldering are required; the pack seats in the existing battery bay and locks with the stock latch mechanism. It is not suited for Chromebook models outside the 15-DE, 14-DA and X360 14-DA families.

Questions about this item

Does the 3-cell 11.55 V lithium-ion pack run hot or draw extra power during all-day use?

The 60.9 Wh cell operates at the same 11.55 V and 5273 mAh as the original, so heat and power draw match the OEM design.

What must I already have in the Chromebook for this SY03XL to install and work?

Your HP Chromebook 15-DE or 14-DA series must use the original SY03XL or L29959-005 battery; the replacement fits the same internal connector and bay.

Will this 60.9 Wh replacement behave the same as the factory battery in my older 15-DE0010NR?

Yes, it replaces the OEM SY03XL directly in the 15-DE0010NR and other listed models, delivering identical voltage, capacity and circuit protection.
