Beisite C31N2020 laptop battery 11.55V 50Wh for Asus Chromebook CX1400 CX1500

Replacement battery for Asus Chromebook CX1400

This 11.55 V lithium-ion pack delivers 50 Wh of capacity and matches part numbers C31N2020, C31N2020-1, 3ICP5/70/81 and 0B200-04010000. It is built for Chromebook Flip CM1 models including CM1400FXA-EC0046, CM1400FXA-EC0023, CM1400FXA-EC0022 and CM1400FXA-EC0014. The black finish matches the original chassis colour. Buyers with other Asus Chromebook models should verify the original part number before ordering.

Fits directly into the existing battery bay

The unit slides into the same compartment used by the factory cell, so no adapter brackets or ribbon-cable extensions are required. It restores mobile operation for systems that currently tether to an AC adapter because the original pack no longer holds charge. Builders who need a second battery for hot-swap workflows will not be served by this single-unit package.

Maintains rated voltage across extended discharge

The lithium-ion chemistry is designed to sustain 11.55 V output during prolonged workloads such as video playback or cloud-based development sessions rather than only during brief benchmarks. Capacity retention follows standard lithium-ion ageing characteristics over the 12-month warranty period. Users who require uninterrupted runtime beyond a single charge cycle should plan for external power.
