What this battery replaces

The Dr. Battery MPL05291P-07 is a new lithium polymer replacement for Dell Latitude 12, 14 and 15 models including the 3150, 3160, E5270, E5450, E5470, E5550 and E5570 series. It matches original part numbers such as 079VRK, 0HK6DV, 0R9XM9, 0TXF9M, 0WYJC2 and 451-BBLN. The cell delivers 7.4V and 6450 mAh capacity.

When the upgrade makes sense

Replace the original pack when runtime has dropped below your mobile workload needs or when the laptop only runs while plugged in. The 51Wh rating restores factory-level endurance for daily office tasks and travel use. A built-in smart control chip provides quicker charging, lower power consumption and longer discharge time with short-circuit, overheat and overload protections.

Check before ordering

Confirm your laptop model appears in the compatibility list and cross-reference the original battery part number printed on your existing pack. Verify the original battery voltage is 7.4V before purchasing. The physical connector and form factor must match the Dell Latitude bay exactly.

Questions about this item

Will the 7.4 V lithium-polymer pack fit the internal battery bay of a Dell Latitude 14 5000 series laptop?

Yes — the pack is built to the same physical dimensions as Dell part numbers 079VRK, 0HK6DV, 0R9XM9, 0TXF9M, 0WYJC2 and 451-BBLN used in Latitude 12, 14 and 15 5000 models.

What is the correct order to connect the battery cable when installing the replacement in a Latitude E5470?

Power off the laptop, disconnect the AC adapter, remove the base cover, unplug the old battery connector first, then plug in the new pack before refitting the cover.

How often should the 6450 mAh cell be recalibrated so the smart control chip reports remaining capacity accurately?

Run a full charge–discharge cycle once every few months to keep the smart chip reporting capacity correctly.
