Replacement battery for Asus Chromebook Flip C436

This 42Wh lithium-ion unit replaces part numbers C31N1845, C31N1845-1, 0B200-03570000 and 31CP4/74/84. It fits the Chromebook Flip C436FA and its many sub-models such as DS599TW, E10005 and E10275. The pack delivers 11.55V and comes in black with an extended cable for easier routing. Buyers needing a different voltage or connector will not find a match here.

Capacity and voltage define the practical limit

The 42Wh rating at 11.55V sets the total energy available for the notebook. Runtime depends entirely on the laptop's power draw, screen brightness and workload, so actual hours will vary. No higher-capacity version of this exact form factor is offered in this listing. Users who need longer unplugged time must look for a different battery design.

42Wh capacity decides fit for your workload

This single figure determines whether the cell can sustain your typical session between charges. Compare the 42Wh value against the original battery's rating printed on your existing pack. If your device shipped with a larger watt-hour cell, this unit will provide proportionally less runtime.
