Dell R8D7N Replacement Battery Review
Dell R8D7N replacement battery, an 11.4V 51Wh three-cell pack for the same Latitude 5400 and Precision 3540 family that also ships with the 4GVMP and 3HWPP.
Three voltages sold for one model name is exactly why we store the code on the pack as the fitment key here rather than the laptop's marketing name.
What to check before you buy
Undervolting the charge circuit with the wrong pack in this family causes early shutdown or a refusal to charge. Match the R8D7N printed on your original pack before ordering, not just the Latitude model number.
