Questions about this item

My Asus C423NA currently runs on the original C21N1808 battery — does this DRPROAS355P-01 replace it directly?

Yes, the DRPROAS355P-01 is listed as a direct replacement for the C21N1808 and C21PQCH batteries used in Asus Chromebook C423NA and C523NA models.

Will the 7.7 V 38 Wh lithium-polymer pack work with the existing charging circuit in my C523NA without a BIOS update?

The battery matches the original 7.7 V specification, so the laptop’s stock charging circuit recognises it immediately — no firmware change is required.

After fitting the battery, how can I confirm the 4940 mAh capacity is being reported correctly by Chrome OS?

Open the Chrome OS power menu or type “battery” in Crosh; the reported design capacity should read 4940 mAh and 38 Wh if the pack is communicating properly.
