This Dr. Battery MPL05308P-15 replaces the original power cell in numerous Dell Inspiron and Vostro laptops. Supported systems include 13, 14, 15 and 17 inch chassis such as the Inspiron 13 5368, 14 7460, 15 5570 and Vostro 14 5468.

Capacity And Chemistry

The lithium-polymer pack delivers 11.4V and 3400mAh, matching the OEM voltage and capacity figures. It supersedes Dell part numbers including FW8KR, P26T, P32E001, P58F, P61F, P62F, P66F001 and P69G001. The upgrade is worthwhile when the original battery no longer holds a useful charge or shows physical swelling.

Sustained Use Behaviour

An integrated smart control chip manages charging current to reduce heat during extended sessions. Built-in safeguards guard against short circuit, overheat and overload conditions while the cell chemistry maintains stable voltage through a full discharge cycle. The one-year warranty covers defects in materials and workmanship under normal operating conditions.

Questions about this item

Will the MPL05308P-15 fit my Dell Inspiron 15 5570 chassis?

This battery is listed as compatible with the Dell Inspiron 15 5570 among other models; verify your original part number matches P26T, P32E, P58F, P61F, P62F, P66F or P69G before ordering.

What is the correct way to install the battery and which step is often missed?

Power off the laptop, disconnect the AC adapter, remove the base screws, detach the old battery connector, fit the new 11.4 V pack, reconnect the cable securely, then reassemble; the step often missed is reconnecting the battery cable before closing the case.

When will the lithium-polymer pack need replacement and what signs should I watch for?

Expect service life to decline after several hundred charge cycles; replace when runtime drops noticeably, the pack swells, or the laptop shuts down unexpectedly despite a reported charge.
