This Dr. Battery MPL05291P-20 unit replaces the original battery in Dell Latitude 12 E5270, 14 5000, 15 5000, 3150, 3160, E5450, E5470, E5550 and E5570 systems. It matches the 7.4V voltage and 6450 mAh capacity of the OEM packs such as 79VRK, 8V5GX, F5WW5 and G5M10. Buyers needing a different voltage or a higher capacity pack should look elsewhere.

Simple internal swap with built-in protection

Installation requires opening the laptop chassis and disconnecting the old pack before connecting the new one. The lithium polymer cell includes a smart control chip that manages charging, prevents short circuits and guards against overheating or overload. No software configuration is needed, but static precautions and correct connector alignment are essential to avoid damage.

Verify model, part number and voltage first

Before ordering, confirm your laptop model appears in the compatibility list and that the original battery part number matches one of the listed codes such as 079VRK, 0HK6DV or 451-BBLN. Check that the original battery shows 7.4V output. This pack is not suitable for Latitude models outside the listed series or for systems requiring a different voltage.
