Beisite C31N2011 11.55V 57Wh replacement battery

This lithium-ion battery replaces part numbers C31N2011 and 0B200-03860000 in Asus Chromebook Flip CM5 and CX5 series devices. It supplies 11.55 volts and 57 watt-hours of capacity for compatible models including CM5500FDA and CX5500FEA variants. The pack is supplied new in black.

Black lithium-ion pack with direct-fit connectors

The battery uses the original form factor and connector layout so it seats in the existing bay without adapters or cable routing changes. Its lithium-ion chemistry matches the factory specification for charge behaviour and thermal characteristics. No additional mounting hardware is required for installation.

Capacity fixed at 57Wh for supported Chromebook

The 57Wh rating defines the energy available per charge cycle and cannot be increased by firmware or settings. Runtime will vary with screen brightness, workload and wireless activity on CM5 or CX5 hardware. Buyers needing longer unplugged time must consider external power banks instead.

Questions about this item

What voltage does the C31N2011 battery deliver, and what does that cap in practice?

The battery delivers 11.55V, which caps the maximum power the Chromebook can draw from the pack without a boost converter.

What physical fit does the C31N2011 need inside an Asus Chromebook Flip CM5 or CX5 chassis?

It matches the original C31N2011 form factor and connector, so it seats in the same battery bay without adapters or shims.

How is the C31N2011 installed, and which step do people often get wrong?

Power off, disconnect the old pack, connect the new C31N2011 connector firmly, then secure the bottom case screws; the step often missed is re-seating the connector fully before screwing the case down.
