Dr. Battery MPL05291P-02 Replacement Battery

This 7.4V 6450mAh lithium-polymer pack replaces original Dell Latitude batteries for models including the 12 E5270, 14 5000, 15 5000, 3150, 3160, E5450, E5470, E5550 and E5570. It suits owners of those specific laptops who need a new power source matching the original 51Wh energy rating. Buyers with other Dell series or non-listed Latitude models cannot use this unit.

Sustained Runtime and Safety Features

The built-in smart control chip manages charging and discharge to deliver longer run times per cycle while reducing power consumption during extended use. Integrated protections guard against short circuit, overheat and overload conditions so the battery remains stable under continuous load. Cell chemistry and circuitry are designed to maintain consistent voltage output throughout the discharge curve.

Compatibility Checks Before Ordering

Verify your laptop model appears in the supported list and cross-reference the original battery part numbers such as 79VRK, 8V5GX, F5WW5, G5M10, HK60W, R9XM9, TXF9M, VMKXM or WYJC2. Confirm the original battery shows 7.4V output and a capacity near 6450mAh or 51Wh. Installing this pack in an unsupported chassis or with a mismatched voltage will prevent correct operation.

Questions about this item

How much heat does the 7.4 V lithium-polymer pack generate during a full day of use?

Lithium-polymer chemistry runs cooler than older cylindrical cells, and the built-in smart chip manages charge current to limit temperature rise during extended sessions.

What must I already own to install the MPL05291P-02 in my Dell Latitude?

A compatible Dell Latitude model from the E5270, E5450, E5470, E5550, E5570, 12 5270, 14 5000, 15 5000, 3150 or 3160 series, plus a small Phillips screwdriver for the bottom case screws.

Will the 6450 mAh capacity work correctly with the original charging circuit in an E5450?

Yes, the pack matches the 7.4 V / 51 Wh specification of the original 79VRK, 8V5GX, F5WW5 and related part numbers, so the laptop’s charger recognises it without firmware changes.
