Replacement Battery for Yoga Chromebook C630

This lithium-polymer battery replaces part numbers L18C4PG0, L18D4PG0 and 5B10R51233 in Lenovo Yoga Chromebook C630 and Chromebook C340-15 notebooks. It delivers 8.2 V and 54 Wh capacity for direct compatibility. Buyers who need a different voltage or form factor cannot use this unit.

Installation and first use

The pack fits the original battery bay and uses the factory connector; verify the part number on the old cell before fitting. The supplier recommends discharging to 5 % then completing three to four full charge cycles to reach rated capacity. Skipping this conditioning step often leaves the pack below its full 7270 mAh rating.

Sustained operation

Rated at 54 Wh, the cell maintains steady output during long work sessions without the voltage sag seen in short bursts. CE, FCC and RoHS certifications confirm consistent safety margins under continuous load. The chemistry is not designed for high-drain gaming or workstation workloads that exceed typical Chromebook power profiles.
