Questions about this item

Does the 11.55 V 42 Wh lithium-ion cell run warmer or draw more power than the original after a full day of use?

The replacement matches the original 11.55 V and 42 Wh ratings, so heat and power draw stay the same as the factory battery under identical workloads.

What must I already own to install the C31N1845 battery in my Chromebook Flip C436FA?

You need a compatible Asus Chromebook Flip C436FA-series chassis and a small Phillips screwdriver to open the bottom case and swap the pack.

Will the 31CP4/74/84 cell work correctly alongside the original charging circuit in a C436FA-E10073 unit?

Yes, the pack uses the same 11.55 V chemistry and connector, so the existing charging controller manages it exactly like the factory unit.
