Questions about this item

How long will the 63 Wh rating actually run my Asus Chromebook CM34 Flip?

The 63 Wh capacity translates to roughly 5427 mAh at 11.61 V, so real-world runtime depends on your screen brightness, workload and power settings rather than the watt-hour figure alone.

Does the 11.61 V output match the original connector and charging circuit on the CX3401FBA?

Yes, this replacement is built to the same 11.61 V specification and fits the listed Asus Chromebook and ExpertBook models without adapter changes.

Will the black lithium-ion pack screw into the existing battery bay on my ExpertBook B3 B3404CVF?

The pack is designed as a direct drop-in for the C31N2205 part number and matches the mounting points used on the supported Asus series.
