Who This Fits and Who It Does Not

Buyers with Latitude E5420, E5430, E5520, E5530, E6420, E6430, E6520 or E6530 models, or Inspiron 14R, 15R and 17R series such as 4420, 5420, 5520, 7520, 5720 and 7720, plus Vostro 3460 and 3560, can use this unit. Owners of other Dell lines, ultrabooks requiring thinner packs, or systems needing a different voltage or connector should look elsewhere.

Match the Original Part Number

Confirm the part number printed on your old battery — for example T54FJ, 8858X, N3X1D, M5Y0X, X57F1, KJ321, 0T54FJ, 312-1163, 312-1164, 312-1242, 312-1324, 312-1325 or 312-1311 — before ordering. Only an exact part-number match guarantees physical fit and electrical compatibility.
