Key facts
Rated battery specificationThese are the seller-stated voltage and capacity figures for this replacement battery.
A part-number decision
This battery makes sense when your original code or exact ASUS model appears in the seller’s list. For an A412FL, verify the printed part number first before ordering.
Buy on AmazonThe useful label is underneath
Your ASUS sits open with its bottom panel off, and the old battery’s printed code becomes the more useful shopping detail.
Match the code, not the family name
This lithium-ion replacement is model C21N1818-2 and is listed under several equivalent part numbers, including C21N1818, B21N1818-2, B21N1818, C21PPJH, and 0B200-03280500. The seller also names specific VivoBook S412, F412, R424, and Y4200/Y5200F series models, rather than confirming every similar ASUS name.
The sensible choice is simple: match the code or exact listed model before ordering; resemblance is not evidence.
