Dr. Battery MPL05291P-14 replacement battery

This 7.4V lithium-polymer pack delivers 6450 mAh capacity for Dell Latitude models including the 3150, 3160, E5270, E5450, E5470, E5550 and E5570. It is built for users who need a direct replacement to restore original run-time on supported machines.

Lithium-polymer chemistry limits

The 7.4V output is fixed by the two-cell polymer design and cannot be changed to suit other voltage requirements. Capacity is rated at 6450 mAh, equivalent to roughly 51 Wh, so run-time will match the original specification rather than exceed it.

Verify model and part number before ordering

Check that your laptop appears in the supported Latitude 12, 14 or 15 5000 series list and confirm the original battery part number matches one of the listed codes such as 79VRK, 8V5GX or F5WW5. Buyers whose device uses a different voltage, connector or form factor will need a different pack.

Questions about this item

Should I pick the 6450 mAh or the 51 Wh rating when ordering?

They describe the same cell — 6450 mAh at 7.4 V equals roughly 51 Wh, so either figure identifies the correct replacement.

What run-time gain should I expect from the 6450 mAh cell in a Latitude E5470?

The 6450 mAh lithium-polymer pack restores the original 7.4 V capacity, giving you the same battery life the laptop had when it was new.

Does the 7.4 V output match the Dell 451-BBLN part requirement?

Yes — the replacement delivers 7.4 V, matching the voltage specified for the 451-BBLN and all listed original part numbers.
