Dr. Battery MPL05291P-19 replacement

This 7.4V 6450mAh lithium polymer battery replaces original Dell part numbers such as 079VRK and 451-BBLN. It fits Dell Latitude 12 E5270, 14 5000, 15 5000, 3150, 3160, E5450, E5470, E5550 and E5570 models. Buyers who need a different voltage or connector layout cannot use this unit.

Simple internal swap with screw access

Installation requires opening the laptop base and disconnecting the old pack before fitting the new one. The built-in smart control chip manages charging and provides short-circuit, overheat and overload protection. A common issue is forgetting to detach the battery cable before removing screws, which can damage the motherboard header.

Verify model, part number and voltage first

Check the service tag or original battery label for an exact match to the listed Dell part numbers. Confirm the original battery shows 7.4V output and a similar physical shape. This pack is not suitable for Latitude models outside the listed series or for systems requiring a higher watt-hour rating.
